Bleach Breakage Tips

Learn how to keep highlights bright without snapping your strands, and stay for the one habit that makes all the difference. We'll also share quick prep steps and after-care tricks that keep colour vibrant.

Patch test wait

A patch test should sit for at least 48 hours before you color. This waiting period lets any skin reaction show up, so you can avoid irritation before the big day.

Patch & Strand Tests

Never skip either test. A patch test checks skin reaction, while a strand test shows how your hair lifts and feels. Both are essential to predict colour lift and prevent unexpected breakage.

Space & Bond Builders

Give your hair 6 to 8 weeks between lightening, touch up only new growth, and ask for a bond-building treatment to protect the protein. Bond builders help reconnect the sulphur bridges that bleach weakens, reducing brittleness.

Prep Before Bleach

Two weeks before, ease off heat tools, use a moisturizing conditioner each wash, and get a light trim. Do the patch test 48 hours prior, and keep a thin layer of natural scalp oil the day before to act as a buffer.

Aftercare First 8 Weeks

After bleaching, condition every wash, apply a mask weekly, detangle wet hair with a wide-tooth comb, keep heat tools below 165 °C, and sleep in a loose braid. These steps keep the cuticle sealed and prevent snap-backs when hair is wet.

The one habit to protect highlights

The one habit that keeps bleached hair from breaking is adding a bond-building treatment right after color, because it helps repair the damaged protein bonds. Think of it as a helmet that cushions the shaft while you style.
