Keratin Hair Mask , Smoothing and Nourishing Frizz-Control Weekly Ritual

For hair that tangles, frizzes, or turns flat between washes, this keratin leave-in mask is the step that makes every other part of the routine work better.

A blend of keratin and collagen forms the foundation of this formula. Keratin rebuilds the hair's natural protein structure where damage has left it rough and porous; collagen adds the kind of weightless body that neither ingredient achieves alone. Because it stays in the hair rather than rinsing out, the benefits accumulate rather than resetting each time. Humidity resistance, improved elasticity, and reduced static are all part of the ongoing effect.

The Ritual

Apply to clean, towel-dried hair from mid-lengths to ends, avoiding the roots if your scalp runs oily. Style as normal. No rinse required. A small amount goes further than expected, so start light and build from there.

Manageable, Shinier Hair That Holds Its Shape

Within the first week, frizz becomes far easier to control and hair holds a style for noticeably longer. After two weeks of daily use, the texture shift is the kind that makes people ask if you've changed your shampoo or found a new stylist. The answer is quieter than that, but the result is the same.
