Summer Hair & Scalp Care for Sensitive Skin: The Rahu Care Routine

Summer is hard on scalps. Sun, chlorine, salt water and sweat all reach the same spot, and if yours is already sensitive or reactive, a few pool days can undo months of careful care. Here is the Rahu Care routine for getting through summer without losing that balance.

Why summer is harder on your scalp than you think

UV exposure oxidises the proteins in your hair shaft, so strands come out drier and more prone to breakage. Chlorine and salt water strip natural oils and throw off your scalp's pH and microbiome, the same balance every Rahu Care formula is built to protect. Add sweat, sunscreen residue and washing more often than usual, and the scalp barrier that normally keeps eczema, psoriasis and general sensitivity calm gets worn down right when you're outside enjoying it the least.

Protect before you swim or sunbathe

Apply PRE-WASH Scalp & Hair Oil to your scalp and lengths 15 to 20 minutes before swimming or a day in direct sun. It sits on the hair as a light barrier, so less chlorine, salt and UV reach the scalp underneath. Same pre-wash step we recommend before any harsh treatment, just moved earlier in the day for pool season.

Wash less

Daily washing "because sweat" is usually the opposite of what a reactive scalp needs in summer. Between washes, PREBIOTIC Dry Shampoo lifts oil and sweat without disturbing the scalp's microbiome the way a daily sulfate wash can. It draws on the same prebiotic base as our shampoo bars, so it's doing real scalp-care work, not just covering things up.

Match your bar to the buildup you actually have

Not every summer scalp needs the same shampoo.

• DETOX Clarifying Shampoo. Activated charcoal and black clay lift chlorine, sunscreen and product buildup after a pool or beach day.
• SCALP Skincare Shampoo. Rosemary extract, salicylic acid and sea kelp bioferment calm the itching and flaking that sun and salt water tend to trigger on sensitive scalps.
• SIGNATURE Prebiotic Shampoo. Your everyday gentle cleanse for the days in between.

Bring moisture back

Sun-dried hair usually needs detangling and moisture more than volume this time of year. Follow with TANGLE Conditioner on rougher, sun-worn lengths, or NOURISH Conditioner if your hair runs fine. While the conditioner sits, a few minutes with the GUA SHA Scalp Comb helps distribute the product and gives your scalp some actual circulation, a bit of rahu on a day that hasn't offered much.

Built for a suitcase, not just a shower

Every Rahu Care bar travels the way liquids can't: no 100ml limit, no bottle to leak in a beach bag. Pack them in the Corduroy Signature Bag and the whole routine fits in one washable pouch.

A simple summer routine

1. Before sun or swimming: PRE-WASH Scalp & Hair Oil on scalp and lengths.
2. After swimming or a sweaty day: DETOX Clarifying Shampoo, or SCALP Skincare Shampoo if your scalp is reactive.
3. Between washes: PREBIOTIC Dry Shampoo instead of a second daily wash.
4. After washing: TANGLE or NOURISH Conditioner, worked in with the GUA SHA comb.
