Benefits and outcomes

Keratin users claim that their hair is smoother and simpler to manage as a result of using it.

Methods and applications

Look for the phrase “keratin hydro lysates” in the ingredients list to identify these goods. In 2013, researchers determined that keratin’s active components were a viable ingredient for people who sought stronger hair.
