Chlorine itch is the term used for the sensitive itchy skin you sometimes develop after swimming in a chlorinated pool or hot tub. The itch may be caused by a sensitivity or allergy to chlorine… or just plain over exposure to chlorine.
Luckily there are easy ways to reduce the effects of pool water chemicals (including chlorine) and naturally protect swimmers.
How Chlorine is Used in the United States
Pools and hot tubs in the U.S. are treated with chlorine to prevent illnesses caused by germs and bacteria found in water. Municipal water systems are also treated with chlorine, EPA guidelines allow up to 4 ppm of chlorine in drinking water (tap water).
We are lucky to have a safe water supply in the United States, but it is important to understand the undesirable effects of chlorine in our water as well.
Why You Should Protect Your Skin from Chlorine
My kids swim year round for swim team and recreation. I love that they are interested in a sport they can participate in whether they are 5 or 95. But spending several days a week in the pool can wreak havoc!
- Swimming in a chlorinated pool means exposure to known skin irritants that can cause skin to become dry and itchy.
- Research suggests that chlorine in swimming pools can increase rates of asthma, cancer, and skin/throat irritation.
- When chlorine mixes with water it forms hypochlorite, a bleaching agent that causes fabrics to fade (Ever notice how faded swimsuits get?).
Chlorine Byproducts
In addition to direct risks, chlorine reacts with organic matter to form chemicals known as trihalomethanes, commonly called “disinfection byproducts.” These dangerous byproducts (including chloroform) are released when chlorinated water reacts with organic matter from swimmers such as sweat or urine. You can read more about trihalomethanes in the EWG 2013 Tap Water Guide.
How to Naturally Protect Swimmers from Chlorine
I hate exposing my kids to dangerous substances but love the enjoyment and exercise they get from swimming. What’s a parent to do?
I’ve decided to reduce chlorine exposure as much as possible and, as Dory might say, “Just keep swimming!”
Five non-toxic ways to naturally protect swimmers from chlorine:
- Wear a swim cap and goggles.
- A tightly fitting swim cap and pair of goggles prevents the chlorinated water from further reaching the hair and eye area.
- Get wet before swimming and rinse off afterward.
- Wetting skin and hair reduces the amount of chlorine you skin and hair can absorb.
- Create a layer of hair protection.
- Spray damp hair with an All-Natural Hair Detangler and Protectant (see my easy recipe at end of post).
- Form a skin barrier.
- Apply a thin layer of natural oil (i.e. avocado, almond, jojoba, argan, or coconut oil) to skin. This light barrier further prevents the amount of chlorinated water your skin and hair can absorb. Smooth the oil on while skin is damp to protect without becoming a greasy blob.
- Use a natural balm to protect lips. My kids use my all natural Healing Dry Skin Balm on their lips, knees, elbows and other dry spots.
- Treat skin, hair and swim gear with a vitamin C solution.
- Vitamin C naturally neutralizes chlorine! I make After Swim Chlorine Neutralizing Spray. See the full recipe below.
How to Use Vitamin C to Neutralize Chlorine (Vitamin C Dechlorination)
Both ascorbic acid and sodium ascorbate (two common forms of vitamin C) will neutralize chlorine (neither form of vitamin C is considered a hazardous substance) according to the USDA.
1. Ascorbic Acid – The chemical reaction of ascorbic acid with chlorine is:
- C5H5O5CH2OH + HOCL → C5H3O5CH2OH + HCl + H2O
- Ascorbic acid + Hypochlorous acid → Dehydroascorbic acid + Hydrochloric acid+ water
2. Sodium Ascorbate – The reaction of sodium ascorbate with chlorine is:
- C5H5O5CH2ONa + HOCL → C5H3O5CH2OH + NaCl + H2O
- Sodium ascorbate + Hypochlorous acid → Dehydroascorbic acid + Sodium chloride + water
How to Make After Swim Chlorine Neutralizing Spray
- Directions: Mix 1/2 tsp sodium ascorbate with 4 ounces of distilled water. Use within 24 hours. (The solution breaks down and looses effectiveness after 24 hours.)
- Use: Generously spray After Swim Chlorine Neutralizing Spray all over immediately after swimming. The vitamin C neutralizes the chlorine.
*Tip: Add a teaspoon of sodium ascorbate to an empty 8 oz water bottle and bring it to the pool. After swimming take the bottle to the shower and fill with water, shake to combine then dump over your hair and body.
Vitamin C Shelf Life
Both ascorbic acid and sodium ascorbate are affordable and have a shelf life of at least one year in a dry form (stored in a cool, dark place). However, once it is mixed into a solution, the vitamin C degrades in a day or two. Mix just enough solution to use each day.
After Swim Chlorine Neutralizing Spray Cost
I currently use Source Naturals Vitamin C Sodium Ascorbate Crystals to make my after swim spray. It cost around $15.00 for 16 oz (approximately 189 days of After Swim Chlorine Neutralizing Spray at $0.08 a day). A similar natural product costs $11.95 for 6 ounces (about 12 days of spray).
Chlorine Removing Post Swim Routine
We follow a simple spray and shower routine to naturally protect ourselves from chlorine damage.
- After swimming spray off with After Swim Chlorine Neutralizing Spray (recipe above) then change and come home to bathe.
I also use a few simple tools to remove chlorine from our water at home:
- Carbon water filters in all of our home showers to remove chlorine.
- These screw on shower attachments cost around $30.00 and use $12.00 replaceable filters that last for up to 6 months. (We have been very happy with the results. Even my father, who is allergic to chlorine, was able to shower without developing itchy skin.)
- Bonus, the filters help keep my shower mold & mildew free and I have to do less scrubbing when cleaning!
- The shower attachments screw on with no special tools, we even take them with us when we move.
- For extra protection: Mix vitamin C into shampoo or body wash to neutralize chlorine or add a few teaspoons of vitamin C to the bathtub.
- You can also use Vitamin C tablets in your bathtub.
Protecting Swim Gear
This routine has helped reduce the amount of fading and breakdown in our swim suits:
- Rinse swim suits in a bucket of water with a teaspoon of sodium ascorbate after each use.
- Pour the whole bucketful (water, suits, and all) into the washing machine, add a scoop of non-toxic detergent, run the washer on the delicate cycle, then hang suits to dry.
- When I'm feeling lazy I toss the suits into the washer with a few teaspoons of sodium ascorbate and detergent then run the delicate cycle.
Protecting Hair From Chlorine
You can protect your hair from chlorine three ways:
- Wet hair before each swim. Wet hair can absorb less pool water.
- Apply a natural product that helps prevent chlorine absorption.
- Wear a tight swim cap.
All-Natural Hair Detangler and Protectant Recipes
- DIY Hair Detangler and Protectant with Essential Oils
- 1 Tbsp Vegetable Glycerin
- 1/2 cup Distilled Water
- 3 drops Argan Oil
- For Rosemary Mint add: 5 drops Peppermint Essential Oil and 5 drops Rosemary Essential Oil
- For Fresh and Floral add: 5 drops Rose Absolute Essential Oil and 3 drops Ylang-Ylang or Lavender Essential Oil
Combine all ingredients in a glass spray bottle. Shake to combine and shake again before applying. Use a few light sprays as a detangling spray after washing or apply generously to damp hair before swimming to protect hair.
2. Easy Hair Detangler and Protectant
Combine 1 oz of natural conditioner (use your favorite non-toxic conditioner) with 8 oz of distilled water. Combine all ingredients in a spray bottle. Shake to combine. Use a few light sprays as a detangling spray after washing or apply generously to damp hair before swimming to protect hair.
I hope these tips and tricks help you naturally protect your hair, skin, and gear so you can keep swimming!

these are great tips. Thanks for linking up to the Bloggers Brags Pinterest Party. I have pinned your post to the Bloggers Brags Broad.
Bren says
Thanks Brandi! I appreciate the support!!
Loretta says
Hi Bren! I suspect my itching is coming from chlorine. I want to try your vitamin c formula, but where do you get that stuff? Also, do you have to leave it on for a certain amount of time before showering? I usually shower at the pool. Thanks for these suggestions.
Bren says
Loretta, you can buy both ascorbic acid and sodium ascorbate (two common forms of vitamin C) on Amazon or at a local health food store. I buy mine on Amazon for convenience. There are links in the post above. Good luck!
Nana says
I love your research, the fact that you include the chemical formulae, and other very useful scientific information. Thank you for doing this for me personally. I have avoided chlorinated pools and hot tubs because of a mild allergy to chlorine and I believe you have given me exactly what I need.
Bren says
Thanks! My dad is allergic to chlorine too, no fun! The vitamin C has worked great for us. I hope it helps you too. You should definitely check out the shower filter if you have city water, it can be more chlorinated than pools!
Jenny says
Can you tell me where the best place to buy Argan oil and vegetable glycerin is? And essential oils? We just bought a house with a pool a few months ago and I want to try these things to limit our exposure to chlorine. Thank you so much for all of these tips!! I found your site off of pinterest & I’m hooked!!
Bren says
I order a lot of my products from Amazon Prime.
Lisa says
My daughter is also a swimmer but has terrible sinus problems from chlorine. Any suggestions for a natural remedy to help?? Thanks! Love your site!!
Bren says
Lisa, I would try to keep as much chlorine out of her nose as possible, those membranes are tender! I think a nose clip could help (but would be hard for a competitive swimmer to wear). Maybe a barrier cream/balm to the inside of the nose before swimming and a rinse with a nettie pot/saline immediately after getting out of the pool? My Non-Petroleum Jelly works well to coat the inside of a nose. I use it on my kiddo who is prone to bloody noses to keep her sinuses from drying out in the pool. Some people also supplement their diet with vitamin C, as they believe it helps rid their bodies of chlorine (I am not a doctor, this is not medical advice…. just one mom repeating info I have heard to another mom!) Also you may want to read up on nettle tea, it seems to help with sinus problems. Hope this helps!
Janel says
My daughter has the same problem. Have you tried to use AFTER SWIM CHLORINE NEUTRALIZING SPRAY inside the nose?
Thanks a lot! I really enjoyed reading these great tips.
Bren says
I have not used it in the nose, I would suggest saline spray first. Thanks for the lovely compliment!
Fran says
is the oil best applied to damp or dry hair? I’ve read contrasting suggestions on the internet. Not sure what is best.
Bren says
Fran, I apply it to dry hair. I would try it both ways and see what works best for your hair.
debbie says
Question,I now know dangers of chlorine pool. What about salt water pools. A lot of pools are going this way. I would like t o know because we are think of changing our chlorine pool over to salt water…I don’t want to go to tHat expense if it isn’t any better for us… thank you so much!!!!
Debbie
Bren says
Debbie, I don’t know much about salt water pools. Here are some articles that might help: Naturally Savvy and Livestrong. Hope this helps! -Bren
dbobby0515 says
Thanks so much for your blog! Ive recently joined the Y and attend water aerobics about 3-4 times a week. I hate the smell and affect of chlorine on my skin and hair! I notice your caution about using the body spray within 24 hours of mixing. What about your bonus recipes for the hair (detangling)? Do they need to be mixed on an “as used” basis? Or is there a bit of shelf life?
Again, thanks so much!
Bren says
The detangler/hair protector last for quite some time (several months). I like to mix the Vitamin c in short periods because it is more reactive.
sarahkempson says
Thank you Bren for this post (I have not been able to browse through your webpage much yet, but it seems to be very helpful). In regards to swimming (as I have grown to love the sport & exercise over the last 2-3 years), I have really sensitive skin (still in the process of trying to find out if I have an autoimmune disorder, or just certain environmental allergies). My question is, you mention the need to use the Chlorine Neutralizing Spray within 24 hours. Have you found this to be the case? For what reason? Thank you.
sarahkempson says
lol – apologies Bren, I didn’t read other posts until after I posted my question. My question was answered in the comment above by dbobby0515. Thank you. Keep up the good work!
Bren says
Glad you found your answer, Sarah! Thanks for stopping by the blog!
Ceci says
Great information! As an Arizona mom, being in the pool in the summer is given for my kids. I’ve always hated the massive chlorine exposure, but your tips & recipes will help! I’m going to give them a try! Would you mind if I “report back” later this summer with a post on my blog? I would definitely link back to this post! Thanks so much!
Bren says
Thanka Ceci! I’d love to hear back on your results!
Yaoyao Fu says
Great DIY! As an avid swimmer, chlorine really bothers me. Thanks for the creative idea! I shared it to my fb as well. 🙂
Mark says
Thanks Bren! I used a cooling pool that had an abundance of chlorine in it, much to my dismay. I started itching that night and it continued into the next day. I found your article and used the Vitamin C crystals in water and it gave me a lot of relief. I think my skin was already burned a bit from the chlorine, so it took until that evening for the itching to subside. Thanks again.
Bren says
I’m so glad it helped, Mark!
Linda says
6 grams of L-Ascorbic acid powder in a teaspoon
i bring 1 tsp of vitamin c powder in an empty water bottle to the shower, fill with hot water while I’m rinsing, dump most of it through my hair and gear, shampoo with a jr ligget shampoo bar, then dump the rest like an apple cider vinegar rinse without the stink to close my cuticle and prevent frizz. no conditioner needed. Chlroine gets deneutralized on contact so there’s no waiting around- rinse it out. Same for the shampoo bar, the jr ligget says wash and rinse. (I used to double wash, double condition, leave in, detangle, etc). I put a bit of the shea butter concoction described below in from the ears down onto damp towel dried hair.
Longest hair and fastest showers in my life.
I was doing the wait till you get home to shower again and got fungus from being wet all day – thick hair
also straight coconut oil works as a deodorant – who knew?
Got rid of all of the lotion in the house, using a 5 Tbsp shea butter mixture beat for 10 mins with 1 tsp argon oil, 1 tsp jojoba, 1 tsp coconut and 1 tsp olive
works for the hair, face, lips, feet
fantastic
the oils and whipping make shea butter spreadable, tried cocoa butter and couldn’t take the smell
hope this helps someone, swimming makes life better- friends makes life worth it
Bren says
Thanks for the great tips, Linda! It takes a village to be a swimmer. 🙁 I can’t wait to try the shea butter mixture. I agree, cocoa butter smell is too strong for me too. Have you tried mango butter? It has even less smell than shea butter. I love it!
Janie Harvet says
Can you leave the vitamin c spray on are should you bathe it off?
Bren says
You can leave it on. We generally shower afterward since we have just been in the pool.
Janie Harvey says
I shower first and after spray on the vitamin c and leave it on. I think it might be turning my hair and fingernails yellow. Have you heard of this?
Bren says
I have not heard of this, you could try using a shower filter that removes chlorine if your concern is chlorine in the shower water. They are affordable, we use them in all our showers.
Carol says
If the kids shower (shampoo, soap & water, not just a rinse) at the pool immediately after swimming, is the post-swimming spray still necessary, or just use the sodium ascorbate rinse in the shower, then shower as usual? Thanks!
Bren says
I like to use the sodium ascorbate rinse in the shower (either before or after they shower) to neutralize the chlorine because 1) the shower water also contains chlorine and 2) a shower alone never seems to get rid of all the chlorine smell in thieh hair/swim suits. Thanks for the great question!
Trinity's Aunt says
My niece was diagnosed with a reaction to chlorine. She says her skin still itches even after the use of cream prescription. Any helpful hints on what to use to help with her discomfort?
Bren says
My dad is allergic to chlorine so he tries to avoid it: no pools, etc. If bathing in chlorine treated water try adding sodium ascorbate to each bath (I use use Source Naturals Vitamin C Sodium Ascorbate Crystals) and/or use a filter on the shower head (I use these carbon water filters in all of our home showers to remove chlorine).
raymond says
Hi Bren,
You provided directions on how to make an after swim chlorine neutralizing spray using sodium ascorbate, but how much ascorbic acid would you use if one cannot find sodium ascorbate?
Bren says
I would use an equal amount. Let me know how it works for you.
Cynthia says
Do you wash the swimsuits every day they swim?
We did learn the hard way that you need to rinse out clothing that you spray with the C or it can stain it. So we make sure to rinse off the skin too just in case it leaves an issue.
‘
Bren says
Yes, I wash them almost every time they swim using cold water and a tiny big of detergent then hang to dry. It helps with fading and seems to make the suits last longer.
Terry says
1. Ascorbic Acid – The chemical reaction of ascorbic acid with chlorine is:
C5H5O5CH2OH + HOCL → C5H3O5CH2OH + HCl + H2O
Ascorbic acid + Hypochlorous acid → Dehydroascorbic acid + Hydrochloric acid+ water
Hydrochloric Acid???!!! That can’t be good. I see you use Sodium Ascorbate in your recipe, but don’t explicitly state whether or not Ascorbic Acid Should or shouldn’t be used. I would think this is a bad option with the byproduct of Hydrochloric Acid… no?
Bren says
You definitely use the one you feel comfortable with. I use Sodium Ascorbate.
Roberta Hubbard says
Thank you so much for this great article, it is just where I am at. I was just diagnosed with hyshimoto thyroid disease, and now swimming might have to go. But I want t protect my lungs from breathing the chlorine as well. Thanks for this info, just what the doctor ordered. 🙂
Bren says
I’m so glad you found it helpful, Roberta!
Secilia Marino says
Looking forward to using the vit. C spray/rinse
My questions is: about wetting skin before pool AND using oil before? In what order? Wet then oil self? oil self then wet before entering pool?
Before going in pool, I always wet hair, add a tiny bit of “leave in conditioner” and put a swim cap on. I also often cover at least my face and neck with coconut oil, sometimes my whole body when I have time.
I only rinse rinse rinse afterwards. And use conditioner on hair. When I shampooed and soaped every time, my skin and hair suffered.
I swim most days 35 min in water, and always itch, it is getting worse, I am getting older and more sensitive, or they are using more stuff in water. When water is warmer, the itch is worse.
Looking forward to making and using Vit C and investigating the shower filter.
Bren says
I would get wet and then apply the oil. A thinner oil like almond or avocado oil is easier to apply when damp.
Enrique says
Thank you so much for this information! It works incredibly well, from the first use you can already tell the difference! You saved my skin and my swimming! <3
Bren says
I’m so happy to hear that you are having great results, Enrique!
Wilfredo says
Hi-
My name is wilfredo, first of it i’ll began by saying, I have 2 kids swimming 3 times per week minimum, 1 an-half hrs every time, we belong to a swim team for the last 7 years, and I have been swimming for the last 3 years in a 25 meter pool and sometimes a 50 meters for 2 time per week each is 1 hrs, all this pools are full of chlorine, but we love the sport, i also have a whole house filtration system to remove the chlorine and fluoride.
I have tried every shampoo and nothing works,
I take a long shower after swimming for one hour , once my skin is dry, i have a very bad smell to chlorine, even the next day, I worry about my kids how bad it could be,
In the future,
The smell never goes away from swimming gear, desperately looking for a solution I came to this site! I am happy that I am about to join you guys!
Question for anyone of you?
After you guys have try this, is there more effective method to use this or mix?
Have anyone have try to mix
The (Sodium Ascorbate Powder with coconut oil or similar) or Is that a bad idea?
Your feed back is very important.
Thank you!
Bren says
Hi Wilfredo! I understand the chlorine smell issue. I would try the Sodium Ascorbate Powder mixed with water after you swim. You can mix it in a spray bottle or add a few spoonfuls to a bath so you can wash is chlorine free water. I think you will see a big reduction in chlorine smell after a few days. Good luck!
Wilfredo Villanueva says
Hello Bren!
Thank you for the reply, I am pitting 2 full spoons of sodium ascorbate on a plastic bottle when kids come out of the pool they fill in with water giving a good shake,-and pore in the head down and make sure they cover the entire body, WORKS EXCELENT, I Swim 2 days per week and I am using it.
Thank you!
Bren says
