The Curl Week

The top of the weight scale, used the way it is meant to be

Top weight in this box

Tops out at 4 of 5

A routine states the heaviest thing in it rather than a single per-application number, because the products in it are used on different days and in a set order. That order is under “How to use” below.

What is in this routine

Bought separately$112.00
As a routine$92.00

Built for curly, coily and coarse hair, which is the one place in this catalog where the heavy end of the scale is the right answer rather than a warning. Nothing in here is trying to be light.

Wash with CL-01, mask with CN-03 for ten minutes, then CN-04 and SR-05 onto soaking-wet hair in sections and dry without touching it. The order matters more than the products do.

Highest weight in the box: 4.

How to use

  • CL-01 on the scalp, rinse.
  • CN-03 on squeezed-out hair, five to fifteen minutes, rinse.
  • CN-04 then SR-05 on soaking-wet hair, in sections.
  • Dry without disturbing it. Do not rake through once dry.

Cautions

  • Not for fine or thin hair. At a top weight of 4 this box is the wrong shape for that problem — The Fine Hair Week is the right one.
  • Contains shea butter, coconut oil and hydrolysed rice protein.
