Treat overprocessed hair to a proper rescue mission. Biolage Bond Therapy Intensive Treatment 150ml is a deep, concentrated treatment made especially for hair that's been pushed to its limits by bleach, colour or heat styling. It's the intensive step that goes deeper than your everyday conditioner, rebuilding strength from the inside out and leaving damaged lengths feeling dramatically softer and smoother.

The magic comes from citric acid, a repairing agent that reinforces the weakened bonds inside the hair to improve strength and resilience. Working alongside it, coconut oil smooths and softens the surface for that silky, healthy-looking finish. Together they leave hair feeling up to 14x smoother*, so it's the perfect weekly boost for hair that needs a little extra TLC.

What it does for damaged hair

Overprocessing breaks down the internal bonds that keep hair strong, which is what leaves it feeling brittle, rough and prone to snapping. This intensive bond treatment targets that damage at its source, reinforcing those bonds while deeply nourishing the hair. Used regularly as part of the Bond Therapy system, it helps reduce future breakage and keeps bleached or colour-damaged hair feeling stronger, softer and far healthier-looking.

How to use it

After shampooing, apply the Biolage Bond Therapy Intensive Treatment generously from mid-lengths to ends, focusing on the most damaged areas. Comb through to distribute evenly, leave it on for five to ten minutes to let the formula work deep into the hair, then rinse thoroughly. Use it once or twice a week alongside the matching Bond Therapy shampoo and conditioner for the full repair routine. You'll find the rest of the range in our professional shampoo collection.

Who it's for

This one's for anyone with seriously damaged, bleached or overprocessed hair that needs a deep, strengthening boost. It suits all hair types, and like every Biolage formula it's vegan with no animal-derived ingredients and certified cruelty-free under the Leaping Bunny programme. We've spent years helping clients in Codsall nurse over-bleached and colour-damaged hair back to health, and a weekly intensive treatment like this is one of the most effective ways to keep that repair going at home.
