Relaxer vs Texturiser: What's the Difference?

Relaxers and texturisers both change the natural curl pattern of the hair, but they give different results. Here is how they compare and what to consider before you use one at home.

What does a relaxer do?

A relaxer is a chemical treatment that straightens the hair by breaking down the bonds that create curl. The result lasts until new hair grows in, when the new growth is usually retouched.

What does a texturiser do?

A texturiser uses similar chemistry but is left on for a shorter time, so it loosens the curl pattern rather than fully straightening it. It suits people who want looser, more manageable curls or waves.

Lye or no-lye?

Lye relaxers use sodium hydroxide. No-lye relaxers use a different active ingredient, such as guanidine hydroxide. Each kit lists what it contains and the strength (for example mild, regular or super).

Safety tips

• Always read and follow the instructions and timings in the kit.
• Do the strand test the manufacturer recommends before you start.
• Do not apply to a broken, irritated or sensitive scalp.
• Use the neutralising shampoo supplied, and condition afterwards.
