How to repair chemically damaged hair

Key Takeaways

• Hair damage is common but treatable: Styling, colouring, and chemical treatments can stress hair, but the right care can restore its health.
• Strengthen with conditioner: Use a nourishing daily conditioner to keep hair cuticles smooth and strong, protecting the vulnerable core.
• Be strategic with chemical treatments: Allow hair breaks between treatments and opt for root touch-ups to minimize overall damage.
• Repair proteins with targeted treatments: For bleached or chemically straightened hair, choose products that specifically repair protein bonds.
• Replenish lipids with oils: Combat frizz and dullness in chemically processed hair by using products with oils to restore lost lipids and boost shine.
• Ensure daily nourishment: Consistently nourish chemically damaged hair to comfort, reduce frizz, and enhance its natural shine.

1 Choose the right conditioner.

When hair cuticles (our hair’s protective armour) are damaged, the core becomes vulnerable. Trust a daily conditioner to keep them smooth and strong, like our Intensive Repair Conditioner .

2 Be tactical with chemical treatments.

We love our highlights, so be smart with chemical treatments. Give your hair a break between each one: if you usually treat it every eight weeks, try waiting 10 weeks. For a colour refresh, touch up roots instead of the whole lot.

3 Find the best treatments.

For bleached hair, look for treatments that specifically repair proteins (hair is mostly made of them) to fix damaged bleached hair.

4 Try a hair mask.

Chemical straightening breaks down hair's protein bonds to reform them into a new shape. If you love the smooth, sleek look, reinforce those proteins with our Intensive Repair Deep Treatment Mask .

5 Look out for oils.

When hair is chemically processed, lipids (the protective layer keeping cuticles smooth and hair shiny) are removed, leading to frizz and dullness. To decrease static and boost shine, choose products with oils to replenish lost lipids.

6 Top up nourishment.

To comfort and nourish chemically damaged hair, ensure daily nourishment. Our Advanced Hair Series Regenerative Nourishment Serum-in-oil helps replicate healthy hair qualities, reducing frizz and boosting shine.
