The first swim of the trip is pure magic. Salt on your skin, sun on your shoulders, and hair that dries into soft, tousled waves on the walk back to your towel.
By day four, it's a different story: dry ends, tangles you can't brush through, and a frizzy halo in every photo.
The good news is that gorgeous beach hair and healthy hair aren't opposites. A few small habits before you swim, a quick rinse after, and the right product for your waves will keep your hair soft from the first swim to the flight home. Here's exactly how.
Why the beach is hard on hair
Sun, salt, and chlorine all pull moisture out of your hair. Salt water dries as it evaporates, chlorine strips natural oils, and hours of strong sun leave ends brittle and color faded. Add wind and humidity, and you have the recipe for frizz.
Fine hair tangles faster, curly hair loses moisture faster, and colored or lightened hair fades fastest of all. Whatever your hair type, the same simple routine keeps it happy.
None of that means you should skip the swim. It just means your hair needs a little care before and after.
Before you swim
Wet it first.
Rinse your hair with fresh water before you get in the sea or the pool. Dry hair soaks up salt water and chlorine like a sponge, while hair that's already wet takes in much less. Most beaches and pools have a shower for exactly this.
No shower nearby? A bottle of fresh water in your beach bag does the same job. Pour it over your hair right before you go in the water.
For Before the Water: The Moroccanoil All-In-One Leave-In Conditioner.
Comb a little through damp hair from the mid-lengths to the ends. It adds a light layer of moisture and slip, so the water has less to strip and tangles come out easily afterward.
Work it through with your fingers so it's evenly spread, then twist your hair into a loose knot. By the time you reach the water, it's already done its job.
For the Ends: The Moroccanoil Treatment Hair Oil.
A few drops smoothed over your ends acts like a protective seal before you swim. A little goes a long way, so start with one pump and add more only if your hair is thick or very dry.
Skip the roots, where oil can make hair look flat by evening. Your ends are the oldest, driest part of your hair, so that's where it counts.
At the beach
Wear it up.
A loose braid or a low bun keeps your hair out of the wind and the water, and it means fewer tangles at the end of the day. Tie a silk scarf over it, or add a wide-brim hat, and your hair stays protected from the sun too.
For Wearing It Up: The Kitsch Large Claw Clips.
Twist your hair up and clip it between swims. A big claw holds thick or long hair without a single dent, and the black and tortoiseshell pair goes with every swimsuit.
Keep it gentle.
Use soft scrunchies or a claw clip instead of tight elastics, which can snag and break wet hair. Save brushing for later, when your hair has been rinsed and conditioned.
For Midday: The OGX Argan Dry Oil Spray.
A light mist over your ends at lunch puts back some of what the sun and salt take out, and the weightless formula won't flatten your waves.
Keep it in your beach bag next to your sunscreen, so reapplying both becomes one easy habit.
After the beach
Rinse right away.
Use the beach shower on your way out, or rinse as soon as you're back at your hotel. Cool, fresh water washes out the salt and chlorine and smooths the hair cuticle, so your hair looks shinier.
Heading straight to lunch? Even a quick rinse under the beach shower and a twist into a claw clip makes a huge difference by the end of the day.
For the Shower: The Moroccanoil Hydrating Conditioner.
You don't need to shampoo after every swim. A thorough rinse and a good conditioner are often enough. Leave it on for a few minutes while you wash off the sunscreen, then rinse with cool water.
For Every Few Days: The Moroccanoil Hydrating Shampoo.
When it's time for a real wash, a gentle, hydrating shampoo cleans out sunscreen and salt without stripping your hair. Follow it with the conditioner and you're set.
For Tangles: The Kitsch Flexi Flow Detangler Brush.
Brush through while the conditioner is still in, starting at the ends and working up. Knots slide out gently instead of snapping, which matters most when hair is wet.
How to get perfect beach waves
This is the fun part. With your hair rinsed and conditioned, the waves are easy, and there's no need for hot tools.
For the Waves: The Moroccanoil Hydrating Styling Cream.
Work a small amount through damp hair and scrunch it up toward your scalp. Let it air-dry in the sea breeze, or twist it into two loose braids before dinner and shake them out when you get to the table. You'll have soft, touchable waves without the crunch.
One big braid gives you loose, romantic waves. Two or three smaller braids give you tighter, beachier texture. Play with it until you find your favorite.
For Humid Nights: The Moroccanoil Frizz Shield Styling Spray.
Mist it over your waves once they're dry to keep frizz down on sticky evenings by the water.
Skip the heat.
Your hair is already working hard in the sun, so give the straightener and curling iron the week off. Air-dried waves look more natural on vacation anyway.
If you want a sleek blowout for one special dinner, go for it. Use the lowest heat setting, finish with a drop of oil, and let your hair rest the next day.
For Overnight: The Silk Pillowcase by Slip.
Silk creates less friction than cotton, so you wake up with smoother waves and fewer tangles. It folds flat into the corner of your suitcase.
Sleep with your hair in a protective hairstyle (e.g. a loose braid) on top of it, and you'll wake up with your waves already done.
For the Finishing Touch: The Sol de Janeiro Cheirosa Hair and Body Mist Set.
A spritz through your waves before dinner, and your hair smells like a warm beach holiday all night.
The upgrade for colored or damaged hair
If your hair is bleached, colored, or already a little fried before the trip, this is where to splurge. Bonding products are made to strengthen hair from the inside, which is exactly what sun, salt, and chlorine wear down. These two are the salon-brand treat in this kit, and they're worth the space in your carry-on.
For Repair: The Redken Acidic Bonding Leave-In Conditioner.
This is the leave-in to reach for if your ends already feel fragile. Redken's acidic bonding formula is made to strengthen and smooth damaged hair, so it works on strength as well as softness, and since it's a leave-in, there's nothing to rinse out. Use it in place of your regular leave-in before you swim and again after you rinse, and give your hair a little extra love every single day of the trip.
For Shine: The Olaplex No. 7 Bonding Hair Oil.
Olaplex No. 7 is the cult-favorite finishing oil, and one tiny bottle goes a long way. A drop or two on dry ends adds glassy, high shine and smooths frizz, and it doubles as your before-swim oil. It's the secret to glossy waves in every sunset photo, and the bottle is small enough to tuck into your clutch for dinner.
Once a week
If you're away for longer, give your hair a reset once a week: a gentle clarifying wash to clear out salt, chlorine, and product, then a deep conditioning mask while you get ready for dinner.
Put the mask on, clip your hair up, and read a chapter on the balcony while it works. It's a little vacation ritual all on its own.

Frequently asked questions
Does salt water damage your hair?
Yes, but you can protect it. Salt water pulls moisture from your hair as it dries, which can leave it rough and tangled. Wetting your hair with fresh water first, using a leave-in conditioner, and rinsing after you swim all help.
How do you protect your hair from chlorine?
Wet your hair with fresh water before you get in, add a leave-in conditioner or a little oil, and rinse as soon as you get out. A swim cap gives the most protection if you're doing laps.
Should you put oil in your hair before swimming?
Yes. A few drops of hair oil on your ends before you swim creates a light barrier against salt and chlorine. Focus on the ends, which are the driest part of your hair.
How do you get beach waves without heat?
Scrunch a styling cream into damp hair and let it air-dry, or twist your hair into loose braids while it dries and shake them out later. Both give soft waves without a curling iron.
Should you wash your hair every day on vacation?
No. Rinsing with fresh water and conditioning after each swim is usually enough. Shampoo every few days, and do a deeper clarifying wash once a week if you're swimming a lot.
Pack the leave-in, the oil, and a claw clip, and let the sea do the rest. Go get that salty, sun-kissed mermaid hair, babe.
