How to use it

  1. Apply a small amount to clean, damp hair, working from ends up to roots.
  2. Use more for longer or thicker hair.
  3. Style as usual: air-dry, blow-dry, or diffuse.

Put it on before heat, in the order its label gives. A leave-in or a styler isn’t a heat protectant unless its maker says so. Air-dry or diffuse: what changes .

What changes your choice

OLAPLEX calls it a styling serum but says it has no holding properties.

OLAPLEX notes ingredients are subject to change and to check the packaging.

What the maker doesn’t say

The maker doesn’t say how much a “small amount” is.

OLAPLEX’s US page doesn’t print the bottle size in its text; the product address ends in “90ml”.
