What this product is
Written from the ingredient list. Where it describes how a formula behaves, that is inferred from what the ingredients are and where they sit in the list, not measured.
Overview
Peptide-132 Ultra Perfect Hair Bonding Treatment is a treatments from COSRX, aimed at wavy hair, curly hair and medium hair. On the evidence of its ingredient list, the formula works on moisture, frizz control and shine. The ingredients doing most of that work are Glycerin, Dimethicone and Cetyl Ethylhexanoate. The list runs to 77 ingredients, 34 of which carry a role we recognise for hair.
How it feels on hair
By the balance of its ingredients the formula reads as neither especially rich nor especially light. It contains Dimethicone, Dimethiconol and Amodimethicone. Silicones smooth the cuticle and cut frizz on contact; they are also what a clarifying wash is for, because they do not rinse out with a mild shampoo. The formula leans to moisture rather than protein.
Protein
There is a small amount of protein in the list: Arginine, Soluble Collagen and Hydrolyzed Vegetable Protein.
On the scalp
For the scalp itself the formula carries Caffeine, Panthenol and Niacinamide. On an oily scalp the richer ingredients here can read as greasy at the roots.
Build-up and porosity
Several ingredients here stay on the hair between washes — Dimethicone, Dimethiconol and Amodimethicone — so on low-porosity or fine hair this is a formula that will want a clarifying wash from time to time.
Where it goes
It is a treatment step: after shampooing, left on, then rinsed out.
What it is not for
Nothing in this formula is aimed at oil control, volume / lightweight, curl definition and color protection — not a fault, just the shape of what is in the bottle, and the reason one product rarely covers a whole routine. No ingredient here is one we recognise as supporting hair growth. Reducing breakage and growing hair are different things, and this formula's evidence is for the first.
In short
Working for it
- No sulfate detergents
