Clayton used a small brush to paint on the solution, which contained cysteamine hydrochloride (HCL), an active ingredient that breaks down the hair’s bonds but minimises the potential for overprocessing so that you can forget about brittle brow hairs post-treatment. “Traditionally, brow lamination solutions were made from glycolic acid, which is very strong and has an eggy smell,” explained Clayton. “This [version] is a softer formula and breaks down the disulfide bonds in the hair very gently.” To comb it through, Clayton actually used a dental brush. “A brush like this is ultra-soft and kinder on the hair than using something tough or wiry, so it doesn’t stretch the hair,” she said. This is key to avoiding overly laminated hair strands that appear pasted to the skin.
