CURLYSHYLL Keratin Booster 150ml is a targeted protein booster that adds keratin to your existing routine.

Keratin is what hair is structurally made of, and damage depletes it. A booster is designed to be mixed into or layered with your treatment rather than replacing it, so you can increase protein when hair needs it and ease off when it doesn't. That flexibility matters, because protein overload leaves hair stiff and brittle.

What are the features and benefits of CURLYSHYLL Keratin Booster 150ml?

• Adds targeted keratin protein to your existing treatment
• Lets you increase or reduce protein as hair needs change
• Rebuilds structure in weakened, damaged hair
• Pairs with the Collagen Booster for a fuller protein approach
