Summer Hair Care: Protection From Sun, Salt & Chlorine
5 min read · Life stages · Anna Schulenburg
Summer hair care is above all protective care: UV radiation, salt water and chlorinated water each stress hair in their own way — they dry it out, bleach its color and roughen the cuticle. The good news: with three simple habits — water before swimming, rinsing afterwards, protection on top — your hair comes through the hot season supple and shiny.
What does the sun do to your hair?
UV radiation creates reactive oxygen species in the hair that attack keratin: the sulfur bonds that give hair its stability get oxidized, the shaft is weakened — hair becomes drier, more brittle and more prone to split ends. At the same time, UV light bleaches both natural melanin and artificial color pigments. That's why color-treated hair fades so quickly in summer — for cool blonde and brunette shades, color-protecting care like the Colour-Enhance™ line is worth it, refreshing color brilliance and visually offsetting brassiness.
A stubborn myth: "Only skin needs sun protection." No — UV damage to hair is measurable. The difference: skin regenerates, but a hair length once damaged doesn't. Prevention is everything here.
Why does blonde hair turn green in the pool?
Surprise: it's not the chlorine itself, it's copper. Copper ions — from algaecides or water pipes — get oxidized by the chlorine and bind to the keratin. This copper-keratin complex shimmers greenish, and it shows most where no dark pigments cover it: in blonde, bleached or porous hair.
The most effective prevention is simple: saturate your hair with clean water before jumping into the pool. A fully soaked hair shaft takes up noticeably less pool water — and with it, less copper. If the green tinge is already there, clarifying shampoos or a trip to the salon will help.
Your summer routine in three steps
Step 1 — Saturate and protect before swimming. Wet your hair through with clean water in the shower and work in a leave-in with UV filter. For beach days: a hat or scarf is the most reliable UV protection there is.
Step 2 — Rinse right afterwards. Don't let salt or pool water dry into your hair — rinse it out with clean water as soon as possible and wash mildly in the evening, so residue never gets a chance to settle in.
Step 3 — Restore moisture and seal. After sunny days, schedule a moisture mask and seal the lengths with a few drops of REJUVENIQE® Oil Intensive — that smooths the roughened cuticle and brings the shine back. How much care your hair really needs after the summer is something the free hair analysis will tell you.
Quick questions
Does hair really need its own UV protection? Yes. UV radiation weakens hair structure and bleaches color. A leave-in with UV filter helps day to day — for hours in the sun, nothing beats a hat.
Which is worse — salt water or chlorinated water? Both strip moisture and roughen the cuticle; pool water adds the copper risk for light hair. The counter-strategy is identical: saturate before, rinse after.
My hair is straw-like after vacation — now what? First wash out residue mildly, then rebuild moisture consistently: masks, leave-in, minimal heat. You'll find the right recovery routine in the guide to dry hair.
Does it help to wash hair less often in summer? After sweat, salt and sunscreen residue, washing is perfectly fine — what matters is mild and lukewarm, not infrequent.
