Overview
A shower routine for damaged hair is where this cream mask belongs: it goes on after shampoo and coats weak strands with a peptide complex, collagen and hyaluronic acid to reinforce them and soften the feel.
Peptide bond repair aimed at breakage and split ends is the reason to reach for it, backed by a short free-from list that suits sensitive scalps. The brand frames it as part of a shampoo, mask and oil trio, so results alone are not promised the same way.
Who it's for
Hair weakened by heat, color or dryness is the target, used a couple of times a week after washing. Those with healthy hair who only want slip for detangling will get little from the bond repair angle.
Pros and cons
- Peptide complex targets damaged keratin
- Collagen and hyaluronic acid for moisture
- Free from sulfates, parabens and phthalates
- Not tested on animals
- Leave-on time not listed
- Brand pushes the full trio for results
- Small tube for long or thick hair
Performance notes
Results depend on how much product reaches the damaged lengths and how often it is used, since the peptide binds to weak keratin rather than coating it once. Hair that is heavily bleached will need repeated sessions for a visible change in breakage.
