How to Make Your Hair Colour Last: 7 Expert Tips

A fresh colour is an investment. These small habits protect it.

• Wait 72 hours before your first wash after colour.
• Wash 2–3 times a week, not daily.
• Sulphate-free shampoo, always.
• Rinse in cool water.
• Weekly bond treatment (K18 is our pick).
• Heat protect before every hot tool.
• Book toner refreshes on time — 6–8 weeks.

Why the first 72 hours matter most

In the first three days after colour, the cuticle is still settling. Wash too early and you rinse toner straight out; use hot water and you open the cuticle before the pigment has locked in. Skipping shampoo for 72 hours is the single biggest thing you can do to add weeks of longevity to your colour — and it costs nothing. When you do wash, use lukewarm water and a sulphate-free formula designed for coloured hair.

Sun, salt and chlorine

Melbourne summers, coastal weekends and daily pool laps are the fastest way to strip fresh colour. UV oxidises pigment; chlorine binds to lightened hair and turns blonde brassy; salt water dries the cuticle. Before you swim, wet your hair with fresh water — saturated hair absorbs less of everything else. Wear a hat on beach days, and rinse thoroughly the minute you're out of the pool.

The bond-treatment habit

A weekly at-home bond treatment — K18, Olaplex or similar — quietly does more for colour longevity than any shampoo. Bond builders repair the internal structure of the hair, which means colour molecules have somewhere to sit and hold. Clients who use a bond treatment weekly consistently stretch their colour appointments by 2–3 weeks compared to those who don't.

Small changes that compound

None of these tips are dramatic on their own. Together, they add up to a colour that still looks salon-fresh at eight weeks instead of four — which saves you money, protects your hair, and means every appointment starts from a stronger base.
