Salon keratin treatments run $300–$400 a visit, and most still leave you breathing in fumes for hours. This is the treatment for people who want smooth, glossy, humidity-proof results without either trade-off.

Formulated with keratin, collagen, and argan oil, it's gentle enough for fine and medium hair — including color-treated strands — while still cutting frizz and taming flyaways in 90% humidity. No harsh chemical smell, no eye irritation. Results last up to 12 weeks with the right aftercare.

Best for: fine to medium hair, including color-treated hair. Coarse or very curly hair will get more out of our Forte Treatment.

Step 1: Wash hair with a clarifying shampoo to remove buildup and prep for treatment.
Step 2: Towel-dry hair and apply the KERAGEN Keratin Smoothing Treatment evenly, focusing on mid-lengths and ends.
Step 3: Blow-dry hair completely to activate the treatment and prepare for heat sealing.
Step 4: Use a flat iron to seal in the keratin, ensuring long-lasting smoothness and shine.

Keratin, Collagen, Panthenol (Vitamin B5), Argan Oil, Jojoba Oil
