Hair consists mainly of keratin-related proteins. Keratin functions both as an internal structural protein in the cortex that helps determine the hair's inner core and its strength, and as an external protective protein within the cuticle. When hair is damaged by sun, chemical or physical environmental factors, keratin in the hair decreases. Lyonsey Keratin Shampoo, with its rich keratin content, helps restore lost or lost keratin and prevents the existing keratin from being lost. In general, IT SOFTENS THE HAIR, PROVIDES DENSITY, PREVENTS LOSS AND BREAKAGE. How to Use: Apply to wet hair by massaging for 1-2 minutes. After it foams, rinse with plenty of warm water.
