Editorial Policy

Product facts

Sizes, named ingredients, directions and the number of applications per bottle come from the brand's product details and labels. A phrase such as formaldehyde-free is the brand's own wording, repeated as stated.

Brand facts

Trademark numbers and dates come from the U.S. trademark register, read on the date shown beside each. Facts about the group behind the brand come from its own pages.

Hair and safety

General points about hair smoothing products are quoted exactly from the U.S. Food and Drug Administration, with a link and the date read.

Prices

We update prices on a schedule. Our last price update was on 10 October 2026. The cost per 100 g and per application is arithmetic on that price.

Reviews

Buyers write the reviews and they appear as written, with the size the buyer chose. A review is one head of hair and one result.
