Hydrolyzed protein

Protein broken into smaller pieces so it can sit on or interact with the hair surface, supporting strength, feel, and temporary damage management.

Hydrolyzed proteins are used when a formula wants temporary strength, body, or damage support. They can help weak hair feel more substantial.

They are not the same as a bond builder, and they are not always ideal for every routine. Hair that becomes stiff may need more softness and less repeated protein.
