Six peptides, keratin, and silk: the actives inside this leave-in conditioner

Hydrolyzed Keratin

Fills weak spots along each strand so hair looks smoother and less prone to breakage.

Silk Protein (Sericin)

Wraps each strand in light-reflecting shine and softens texture without adding weight.

6-Peptide Complex

Copper peptide (GHK-Cu), Hexapeptide-11, Acetyl Tetrapeptide-2, Myristoyl Pentapeptide-17, and Matrixyl 3000 help strands look stronger over weeks.

Strands that have been through a lot need more than a regular conditioner

Flat irons, bleach, color, tight ponytails, a hard brush through wet hair. Every one of them leaves a mark, and it all shows up at the ends: split, frayed, frizzy, and quicker to snap than they used to be.

Strand Strengthening is a leave-in conditioner for damaged hair. Keratin and silk protein smooth the look of frizz from the first use, while six peptides help strands look stronger over 4 to 8 weeks, from mid-lengths to ends.

Smooth on day one. Stronger-looking by week eight.

Hydrolyzed keratin, the same protein your hair is made of, fills weak spots along each strand so it looks smoother and less prone to breakage. Silk protein (sericin) wraps it in light-reflecting shine without adding weight.

Layered underneath, the 6-peptide complex works at the strand level to visibly reinforce hair, helping improve the appearance of frizz and breakage over time.

Soft enough to notice. Light enough to forget.

A silky lotion that melts into damp hair and lets a comb glide through without a fight. It takes seconds, needs no rinsing, and fits into whatever routine already works for you, whether you air-dry or blow-dry.

Once it dries, hair feels soft and looks polished, with its movement intact. Strands stay light, never greasy or weighed down, so the difference shows in how your hair moves as much as how it looks.

Is this multi-peptide leave-in conditioner right for your hair?

How to use and store

After washing, towel-dry until damp. Work 1 to 3 pumps through mid-lengths and ends, comb through, and do not rinse. Style as usual. Use after every wash. Store at room temperature, away from direct sunlight.

    I noticed fewer hairs in my brush after three weeks. My ends feel stronger and look less frayed. It doesn't weigh my hair down or leave it greasy. I use it after washing, and I'll keep going.
