“A keratin treatment is a chemical procedure done in a salon, or at home, that can make hair look straighter and smoother,” says Patterson. “It can last 4–6 months, adds intense shine, and reduces frizz.” In order to get these outcomes, a protein system is utilized to the hair and left to course of, then sealed with a blow dryer or flat iron in skinny sections. 

“I like to explain a keratin treatment similarly to a gel manicure that is cured and hardened under a curing light,” says Patterson. “The product becomes set and cured, and remains that way until it gradually fades off in about four to six months.”
