Keratin and the Ocean Don’t Mix: How to Protect Your Hair This Summer
Keratin treatments are a game-changer for anyone struggling with frizz, especially during hot and humid months. They dramatically reduce styling time, add shine, and keep unruly hair smooth for weeks. But before you book your seaside getaway, there’s one thing you should know: saltwater can undo all the benefits of your treatment.
Here’s what every keratin-treated beauty needs to know before hitting the beach or pool.
Why Salt Water and Chlorine Spell Trouble for Keratin-Treated Hair
Saltwater contains sodium chloride, which can penetrate the hair cuticle and break down the keratin coating applied during your treatment. This leads to:
-
Loss of smoothness and shine
-
Increased dryness and frizz
-
Shortened lifespan of your keratin treatment
Unfortunately, chlorine — commonly found in pools — has a similar effect. It strips hair of moisture and weakens the keratin bond, leaving your strands vulnerable and rough.
What to Do If You Still Want to Swim
Let’s be honest: it’s summer, and sometimes skipping the water just isn’t realistic. If you do decide to swim:
-
Pre-wet your hair with clean water first. Saturated hair absorbs less salt or chlorine.
-
Apply a leave-in conditioner or hair oil to form a protective barrier.
-
Wear a swim cap when possible — not glamorous, but highly effective.
-
Rinse your hair immediately after swimming and follow with a gentle, sulfate-free wash.
These measures won’t guarantee 100% protection, but they will significantly slow down the damage.
Post-Treatment Tips: The First 72 Hours Matter Most
The first three days after your keratin treatment are critical:
-
Avoid washing your hair entirely — even water exposure can weaken the treatment.
-
Keep your hair loose. No ponytails, buns, or clips — tension can create dents or frizz.
-
Avoid humidity and sweating as much as possible.
Once the three-day window has passed, you can go back to your usual care routine — just make sure your products are sulfate-free to maintain results for as long as possible.
Keratin treatments and summer vacations can go hand-in-hand — but only if you’re mindful. Avoid saltwater and chlorine whenever possible, and prep your hair if you do take a dip. With a little extra care, you can enjoy smooth, frizz-free hair all season long.
