Shampoo

Massage into wet hair, lather, and rinse thoroughly.

The Four Reasons Professional Volume Boost line is your tool for fine, thin, and flat hair, as well as for anyone who desires more volume. Professional Volume Boost Shampoo contains Hydrolyzed Protein, which adds fullness and airiness to the hair. Panthenol makes the hair soft and moisturizes without weighing it down. The shampoo leaves the hair smooth and shiny. When Panthenol and Hydrolyzed Pea Protein are used together in hair care products, they enhance hair thickness, volume, and moisture. Panthenol's moisturizing, strengthening, and conditioning properties complement the film-forming, moisture-retaining, and antioxidant benefits of Hydrolyzed Pea Protein. The protein content of Hydrolyzed Pea Protein helps strengthen hair structure, while Panthenol's vitamin content ensures long-lasting moisture and improves hair elasticity.
