Chlorine and colour-treated hair: what to know

Chlorine keeps our water safe — but it isn't doing your hair colour any favours.

Why chlorine is in your shower water

Chlorine is commonly used to disinfect tap water across the UK. It's effective and safe to bathe in, but repeated exposure in the shower can leave hair and skin feeling dry, tight or stripped.

What it means for colour-treated hair

Freshly coloured hair is an investment. Chlorine exposure may contribute to dullness and faster-looking colour fade — which means more frequent salon visits to keep your colour looking its best. If your colour seems to lose its vibrancy sooner than it should, your daily shower could be a contributing factor.

Protecting your colour between appointments

• Wash with cooler water — very hot water can open the hair cuticle and accelerate fade.
• Use colour-safe products — your stylist can recommend the right ones for your hair.
• Filter your shower water — reducing chlorine and mineral exposure at the source helps protect your colour every single day, without adding a step to your routine.

The Purified Beauty Shower Filter was created by a professional hairstylist after seeing how water quality affected clients' colour over time. It's designed to help reduce chlorine, heavy metals and hard water minerals before they reach your hair — see how it works.
