It's that time of year when holidays are calling, and if we're lucky enough, that will means sunshine, relaxation and the irresistible pull of the pool. A dip is a must, right? Of course it is. But while you might love the water, your hair might not feel the same way.
Chlorine, found in most swimming pools, is a powerful disinfectant - great for keeping the pool clean but not so great for your hair. It can strip away moisture, weaken strands and even alter the colour of your hair, especially if it's bleached or dyed. And if you're swimming outdoors, the combination of chlorine and strong sun can be extra damaging.
The good news is you don't have to choose between swimming and healthy hair. With a few simple prep and aftercare steps, you can enjoy the water and keep your hair looking and feeling great. Here's how to build your pool-proof routine.
Pre-Pool Hair Routine
Prep your hair with fresh water
Wetting your hair with clean, fresh water before swimming is a simple but effective way to protect it. Hair is absorbent like a sponge; if it's already saturated with clean water, it won't soak up as much chlorinated water.
Most pools encourage a pre-swim rinse for hygiene reasons, but it's also one of the easiest ways to reduce chlorine exposure. So next time you head to the pool, make a quick stop at the showers, and your hair will thank you later.
Apply a protective product
Before getting in the pool, applying a leave-in conditioner or a light oil can create a barrier that helps shield your hair from chlorine. These products coat the hair shaft, sealing the cuticle and reducing how much chlorine can penetrate and cause dryness.
If you're swimming outside, consider using Oway Sunlight Serum, which not only helps protect against sun, salt and water, but also nourishes and polishes the hair without weighing it down or feeling greasy. For coloured hair, opt for Oway Colour Protection Veil instead - this lightweight mist protects against oxidative stress while helping maintain vibrancy.
Tie it up
Wet hair is more fragile and prone to tangling, so securing it before swimming offers double the benefit of less breakage and less exposure to chlorine.
While swim caps help keep hair contained, remember they can also trap chlorinated water against your hair, especially in the heat, so be mindful if you're spending long hours swimming outdoors.
Instead of a tight braid, which can create tension (especially as hair dries and tightens), try tying your hair in a loose plait or bun secured with a silk scrunchie. This gives your hair some slack, reducing stress on the strands while still keeping it neatly out of the way.
Post-pool Hair Routine
Rinse immediately after swimming
Once you're out of the pool, rinse your hair as soon as possible. This washes away lingering chlorine before it dries into your hair and causes more damage.
The longer chlorine sits on your hair, the more it can dry it out, dull your colour and create that straw-like texture no one wants. Even if you can't shampoo right away, a thorough rinse is a crucial first step in your post-swim routine.
Use a clarifying shampoo
Clarifying shampoos are designed to remove build-up - after swimming, that means chlorine and mineral deposits. If you're swimming frequently or your hair feels coated, a weekly clarifying shampoo can help reset your hair and scalp.
If you're on holiday and swimming daily, consider using Oway Sunway After Sun Hair and Body Bath, a gentle cleanser designed to remove chlorine, salt and product residue.
Deep condition and repair
Regular swimming can strip your hair of moisture and weaken its structure. Once or twice a week, treat your hair to a deep conditioning mask. If you're travelling or spending a lot of time in the sun, Oway After Sun Hair and Body Mask is a great option.
How to use it:
After cleansing, towel off excess water and apply the mask strand by strand from lengths to ends, massaging gently for a couple of minutes. Leave it on for at least five minutes before rinsing thoroughly. For an intensive treatment, leave it on by the pool during the day or overnight. If your hair isn't coloured, follow up with a clarifying shampoo to remove any residue. For coloured hair, stick to the Sun Hair and Body Bath instead.
Colour-treated hair? Take extra care
If your hair is dyed or bleached, it needs a little extra care around the pool. Colour-treated hair is typically more porous, meaning it soaks up chlorine more easily and the results can include dullness, brassiness or even a greenish tinge in blonde hair.
Stick to sulphate-free, colour-safe shampoos and masks after swimming to help preserve your colour. Deep hydration is essential here too, to counteract both the dryness from chlorine and the fading from sun exposure.
If your colour's looking faded or uneven post-holiday, ask your stylist about restorative treatments to get things back on track.
Don’t forget UV protection
If you’ll be out in strong sun, wearing a hat is one of the easiest ways to shield your hair and scalp from UV damage. When applying sunscreen, remember to cover your parting, hairline and the tops of your ears to avoid burning.
Getting your hair back on track after your holiday
If your hair feels faded, dry or lacklustre after weeks of sun and swimming, consider booking an appointment for a gloss colour. A gloss adds shine and subtle tone, enhancing your hair’s smoothness and vibrancy in one simple treatment.
Keep your hair happy, all summer long
A little preparation goes a long way when it comes to protecting your hair from chlorine. Whether you're a regular swimmer or just heading away for a summer break, these simple steps can help keep your hair healthy, hydrated and strong.
