You get out of the pool feeling great, then later you catch your reflection, and your waves look crunchy, dull, and a little angry. If that sounds familiar you aren’t alone. Wavy hair has a love-hate relationship with pool water, and I learned the hard way that a summer of daily swims can leave my curls stiff and straw-like.
The good news is? A few simple steps right after you swim can save your waves from most of the damage. Here’s your step-by-step guide to what pool water does to wavy hair and how to deal with it. What you’ll get:
- How chlorine and sun mess with your wave pattern
- A simple after pool routine that actually works
- Common mistakes that silently kill your hair.
Why Pool Water Is Rough on Wavy Hair
Wavy hair is in a bad spot. It’s drier than straight hair because the natural oils from your scalp can’t travel down the bends in each strand as easily. That alone makes your waves thirsty, so anything that siphons moisture away has a bigger impact.
And that’s just what pool water does.
What chlorine does to your strands
Chlorine keeps the pool water clean, but it’s bad for your hair. According to the American Academy of Dermatology, chlorine breaks down the natural lipids that coat and protect each individual hair strand. It can also break down the protein bonds in the hair, which leads to more breakage and split ends.
Imagine those lipids like a light raincoat for your strands. Strip it away, and water rushes in and out too fast, leaving hair dry, brittle, and frizzy.
How it affects your wave pattern
The cuticle is the outer layer of each strand and is made up of tiny overlapping scales. When your hair is healthy and moisturized, all those scales lie flat and your waves clump and curl nicely. Those scales are elevated by chlorine and friction. The result is a rough texture, frizz, and loose, stringy, or undefined waves.
The sun adds to the problem.
The UV rays from swimming outdoors put more stress on your skin. UV light also damages hair proteins, which can result in dry, brittle, dull hair, says the AAD. Lightening or colour-treated hair usually suffers the most.
Quick takeaway: Pool water dries out wavy hair, roughens up the cuticle, and weakens the strand, all of which kill your definition.
Your After-Pool Routine for Wavy Hair
The number one rule: move quickly. The longer chlorine is in your hair, the more it damages. And this is the routine I use, step by step.
Step 1: Rinse right away
First thing, head for a shower, and rinse your hair with cool or lukewarm fresh water. This takes out most of the chlorine before it settles in. A quick rinse does wonders.
Pro tip: Wet your hair with clean water before you jump in. Hair is not a good sponge, so if you already have a lot of fresh water in there, it will take up less water from the pool. The AAD also recommends putting on oil or a leave-in conditioner before swimming to create a protective shield.
Step 2: Shampoo only when you need to
You don’t need to suds up every time. Plain water may need only a quick rinse and a light swim. For longer pool days, use a gentle sulfate-free shampoo or a clarifying or swimmer’s Shampoo once or twice a week to lift out built-up chlorine.
Don’t get ahead of yourself. Shampooing daily with harsh shampoo strips out more moisture and leaves waves dry and puffy.
Step 3: Deep condition to put moisture back
This is where your waves come alive again. After shampooing, work in a rich conditioner or a deep conditioning mask and leave it on for a few minutes. Work on mid-lengths and ends, where hair is oldest and weakest.
Look for ingredients such as:
- Argan oil OR Shea butter to soften
- Glycerin for moisture attraction
- Proteins, hydrolyzed for strength (use these sparingly)
Step 4: Detangle gently
Wet hair stretches and breaks easily, so don’t hurry. Comb with wide teeth or fingers, starting at the ends and working up to the roots. Don’t rake a brush top down through soaking wet waves. That’s a quick route to breakage.
Step 5: Add a leave-in and define your waves
While your hair is damp, smooth in a leave-in conditioner or curl cream. This seals in moisture and helps your wave pattern clump back up. Scrunch up towards your scalp to encourage the curl and then leave it alone.
Step 6: Air-dry or use low heat
Go for air drying your hair if you can. If you’re in a hurry, use the diffuser on a low heat and speed setting. High heat on already stressed hair leads to more dryness and frizz.
Quick takeaway: Rinse fast, shampoo sparingly, deep condition, detangle gently, use a leave-in, and avoid high heat.
Best Practices to Protect Waves Before You Even Swim
A little prep work saves you a lot of repair work later.
- First, wet your hair with clean water so it doesn’t absorb as much chlorine.
- Dermatologists recommend using a barrier, such as a light coating of oil or leave-in conditioner.
- Use a swim cap for longer swims or lap sessions.
- Tie long waves back in a loose braid to help cut down on tangling and friction.
- And dry your ears too. To prevent swimmer’s ear, the CDC recommends tilting your head and gently drying your ears after swimming, as water can get trapped in your ears and lead to infection.
Common Mistakes to Avoid
I’ve made most of these mistakes myself, so learn from me.
- Sitting chlorine. And at worst, you walk around for hours with wet, chlorinated hair.
- Overwashing. Shampooing every time strips the natural oils your waves are craving.
- Roughly brushing soaking wet hair. Resulting in snapping, frizz.
- Skip the conditioner. Wavy hair needs its moisture replenished every time.
- Dry with a rough towel. A regular towel scrubbing lifts the cuticle. Instead, blot with a soft cotton t-shirt or microfiber towel.
- Turn the blow dryer to high. Heat + chlorine = crispy waves.
Expert Tips for Healthier Waves
Here are some extra habits that really add up over time:
- Try a vinegar rinse. Try a diluted apple cider vinegar rinse (about 1 tablespoon per cup of water) to help remove buildup and smooth the cuticle. Use it every now and then, not every day.
- Leave a leave-in in your gym bag. Quick access means you’ll actually use it.
- Prune regularly. Snip the split ends every couple of months, and that will stop the breakage from creeping up the strand.
- Rehydrate from the inside out. No food can repair external chlorine damage by itself, but drinking plenty of water and eating balanced meals can help your hair overall.
- Protect color-treated waves with extra care. The AAD says that it’s more susceptible to damage from chlorine and UV rays when it’s bleached and lightened.
When to See a Dermatologist
Most pool dryness can be fixed at home. But keep an eye on your scalp and your shedding. If you experience ongoing itching, redness, flaking, irritation, or hair loss that appears to be more severe than usual and does not improve, it is advisable to seek the advice of a board-certified dermatologist. The same goes for a dryness that won’t go away, no matter what you do. A professional can rule out scalp conditions and give you advice on your hair.
Frequently Asked Questions
1. After each swim, is it compulsory to shampoo my wavy hair?
Not always. After a short swim, a good rinse in fresh water is usually all that is needed. Shampoo for longer pool sessions or when your hair feels coated and stiff.
2. Does chlorine mess up wavy hair?
No. Chlorine dries and breaks hair over time, but if you rinse quickly, condition regularly, and get trims, your waves can stay healthy.
3. Why does my wavy hair lose its curls after the pool?
Chlorine damages the cuticle and dries out your strands, so they lose definition. Usually, moisture added back with conditioner and a leave-in brings the wave pattern back.
4. Can I just use regular Shampoo instead of swimmer’s Shampoo?
Yes, a light sulfate-free shampoo works for most swims. A clarifying or swimmer’s Shampoo only works better at removing stubborn chlorine buildup when used occasionally.
5. How to prevent frizz after swimming?
Rinse briskly, deep condition, detangle softly, and put on a leave-in when wet. Air dry or use a diffuser on low heat to lessen frizz.
6. Do you really need a swim cap for wavy hair?
Not required, but helps a great deal for long swims or laps. If a cap isn’t your beauty wheelhouse, slathering your hair in oil or leave-in before you hit the pool is a solid backup.
7. Why do I feel like my ears are blocked after swimming?
Water stuck in the ear canal can cause pain or infection. The CDC recommends that after every swim, you tilt your head and carefully dry your ears.
Keep Your Waves Happy All Season
It doesn’t have to be dry, frizzy hair after a day at the pool. The whole trick is to act fast and give your waves the moisture chlorine steals. Rinse immediately after leaving the water Shampoo when necessary. Deep condition each time. Be gentle with wet hair.
Your next easy step is to assemble a small kit with a leave-in conditioner and a soft microfiber towel and carry it wherever you swim. Develop the habit, and your waves will be rewarded with softer, bouncier, healthier-looking curls all season long.
