"I love it. My hair is still like the day I did the ketarine :)" - Egui

Why You’ll love it

Adds a light, polished shine that makes colour and cut stand out.

Description

Alfaparf Keratin Therapy Lisse Design Keratin Serum is a smoothing leave-in serum that tames frizz fast.

This lightweight, silky formula coats each strand with keratin and precious oils, helping hair look smoother and more polished without weighing it down. It glides through damp or dry hair, leaving a soft, satin-like finish with a subtle, salon-clean scent.

Perfect for frizzy, unruly, or chemically straightened hair, it helps keep lengths sleek between keratin treatments. Use it before blow-drying for smoother styling, or on dry hair to calm puffiness and flyaways.

Hair feels easier to brush, less rough to the touch, and more controlled from root to tip, so your styling feels quicker, calmer, and more predictable every day.

Directions

How To Use Alfaparf Keratin Therapy Lisse Design Keratin Serum

Apply 1–2 pumps to clean, towel-dried hair.
Distribute evenly through mid-lengths and ends.
Do not rinse; style with a hairdryer or let air-dry.
Use a small amount on dry hair to smooth frizz and add shine.
Adjust quantity based on hair length and thickness.
