What Is Keratin
It's a protein that's naturally in your hair.

How It Works: A stylist applies a keratin hair-straightening product to your hair and then uses the heat of a flat iron to seal it in. The process takes about 90 minutes or longer, depending on your hair's length. Salon keratin products include Keratin Complex Smoothing Therapy by Coppola, Global Keratin Complex, the La-Brasiliana treatment, Brazilian Keratin Treatment, the Brazilian Blowout, and Brazilian Hair Straightening.

Farewell, Frizz: You can forget about frizzy hair after treatment. “You could walk out in moist or light rain and your hair wont change,” Borday says.

Usage: Wash hair with shampoo (2) Dry the water with towel, (No need dry with dryer) Apply hair mask on hair, don't touch scalp, constantly massage hair for 2-5 minutes (3) Finally, rinse hair completely.
