Bleach gives gorgeous results — but it's the harshest thing most of us do to our hair. If yours has gone dry, straw-like or snappy after lightening, here's how to nurse it back.
Why bleach damages hair
Bleach works by opening the cuticle and breaking down pigment — but in the process it also weakens the internal bonds that give hair its strength and elasticity. The result is hair that's more porous, drier and far more fragile, because the protective cuticle no longer lies flat (Scientific American). Over-bleached hair can become so weak it stretches and snaps when wet.
How to repair bleached hair
- Press pause on bleach (and heat). Repair can't begin while you keep lightening.
- Use bond-building and protein products to rebuild internal strength.
- Balance protein with moisture — masks and leave-ins keep it flexible, not brittle.
- Be very gentle when wet, when bleached hair is weakest: no rough towelling, detangle with a wide-tooth comb from the ends up.
- Trim the worst ends. Frayed, split ends won't recover and cause more breakage.
- Protect from heat and sun with a heat protectant and, where you can, a hat in strong sun.
The salon fix: reconstruction
For bleached, brittle hair, a hair reconstruction treatment is the most effective repair — it rebuilds the internal structure and restores strength and softness, and is often done as a short course. For dryness and dullness, hair botox deeply hydrates and smooths. Many clients do reconstruction first, then a smoothing treatment once the hair is stronger.

A note on more colour or smoothing
If you're dreaming of a keratin or smoothing treatment on bleached hair, get the hair strong first — we'll always assess condition and may recommend reconstruction beforehand so the smoothing treatment helps rather than stresses fragile hair.
