Overview

HASK makes this Smooth Keratin deep conditioner as a restorative treatment for frizzy, unruly hair. Keratin helps repair damage and static, applied to clean, wet hair and rinsed after a short wait.

Smoother, shinier hair with less breakage is what a weekly session aims for. Each use needs a wait in the shower before rinsing.

Who it's for

Weekly treatment nights for damaged or frizzy hair suit these packets. People wanting an everyday conditioner should use a standard formula.

Performance notes

Keratin proteins fill weak spots along damaged strands, which reduces breakage and frizz. A longer leave-on time lets the treatment absorb before rinsing, and jojoba adds slip for smoother hair.
