Summer hair‑care guide to keep dyed blonde hair vibrant

Experts explain that summer exposure to UV radiation, chlorine and sea salt accelerates colour loss in dyed hair. UV light breaks down pigment molecules, chlorine acts as an oxidising agent and salt dries the cuticle, making the hair more porous and prone to fading.

To protect colour, they recommend not dyeing hair immediately before a beach or pool trip; allow at least a week for the cuticle to close. Use shampoos and conditioners with UV filters and antioxidants, reapply protective sprays throughout the day, and shield hair with hats when sunlight is intense. Before swimming, rinse hair with fresh water to reduce chlorine and salt absorption, and consider a professional diagnosis of hair health to choose suitable hydrating and strengthening products. The advice is backed by Spanish experts from Secretos del Agua and hair‑care specialist Viktoria Petrova of the Method Molecular.

Following these steps can help dyed blonde hair retain its brightness throughout the summer months.
