Hair serum with Silk and Keratin.
Hydrolyzed silk protein has the ability to feed hair with new keratin protein and thus strengthen weakened hair. It penetrates the hair shaft so that the hair is moisturized and strengthened from within.
Also, since silk protein is the strongest natural fiber known, when the protein penetrates the hair, it creates a protective barrier around each hair that protects the hair from further damage.
Like no other protein, hydrolyzed silk protein improves hair shine, adds elasticity to hair to prevent breakage, and helps hair retain moisture for longer periods of time.
