HAIRMED: How to prepare your hair for the sun?

Published: 4-Jun-2026

The Deep Hydration Ritual with R4 to protect and strengthen hair before exposure to sun, sea, and heat

Sun, salt water, chlorine, and frequent washing can alter the balance of the hair fiber, making hair drier, duller, and more fragile. To address this need, HAIRMED created the Deep Hydration Treatment, a ritual designed to help hair maintain elasticity, softness, and protection throughout the summer season.

R4: The hydrating and protective treatment before summer

At the heart of the routine is R4 Hydrating and Protective Reconstructing Fluid, a professional treatment developed to restore the hair fiber’s natural ability to retain water and maintain proper hydration levels for up to three weeks.

Its formula stands out thanks to the combined action of:

  • Hydrolysed collagen, which deeply hydrates, regulates moisture levels, and protects against dryness, restoring elasticity and softness.
  • Hydrolysed keratin, which bonds to the hair structure to repair damage and strengthen the fiber.
  • Natural prebiotics from beetroot and oligosaccharides, which help preserve the balance of the skin and hair microbiome, keeping hair healthy, shiny, and silky.
  • Crosslink Technology, which anchors keratin and collagen to the hair fiber, ensuring deep, long-lasting hydration for up to four weeks.

The treatment is enriched with date-derived melanin, wasabi, and the SOD enzyme, antioxidant ingredients that help protect hair from sun exposure, oxidative stress, and environmental aggressors.

The treatment is particularly recommended during the pre-summer period, when the hair fiber needs to be prepared and strengthened before exposure to the sun, sea, and heat.

The HAIRMED deep hydration ritual

For a complete treatment, HAIRMED recommends using R4 as part of the Deep Hydration Ritual, together with:

- B9 — Hydrating Eudermic Bath

A gentle shampoo formulated with cleansing agents derived from coconut-based plant sources. It is ideal for cleansing the hair while respecting the scalp’s natural balance, even with frequent washing.

- N6 — Hydrating Mask and Co-Wash

An intensive conditioner to be used after shampooing or, when needed, as an alternative cleansing method using the co-wash technique. Rich in hydrolyzed keratin, plant extracts, and prebiotics, the N6 mask nourishes and protects the hair fiber, leaving hair soft, shiny, and elastic—even after a day in intense sunlight.

For HAIRMED, preparing hair for summer means adopting a preventive approach to hair care: protecting and strengthening the hair fiber before sun exposure and other external aggressors compromise its balance and well-being.
