The formula you chose

DEEP RECONSTRUCT HAIR MASK

Deeply conditions and smooths hair

Deeply conditions and strengthens the look of hair.

The texture

A rich weekly rinse-off hair mask led by Cantharellus Cibarius (Chanterelle) Extract, a conditioning botanical, with humectant Sodium PCA and Brassicyl Isoleucinate Esylate, a rapeseed-derived conditioning agent. A layered base of coconut, avocado, evening primrose, and sweet almond oils smooths the appearance of the cuticle across a longer weekly wear window, composed for dry and chemically treated hair.

The study behind it

Hydrolyzed Keratin is a hair protein studied in cosmetics for forming a smoothing film on the fibre and helping it hold its strength, so this weekly mask restores the look of stronger, smoother, less damaged hair.1

  1. 1 Fan J, et al. Molecules, 2025 (PMID 40076404).

How to use it

  1. After shampooing, apply a generous amount to wet hair from mid-lengths to ends, working through with a wide-tooth comb to distribute evenly.
  2. Leave for 10 to 20 minutes, then rinse thoroughly.
  3. Use once weekly.
