One product. One part of a larger approach.
Hair appearance is commonly discussed as a single concern. In reality, how hair looks and feels depends on several factors, from scalp condition to fiber strength. SYNERGY45 was built as a multi-product cosmetic system so that different products can address different aspects of scalp condition and hair appearance.

It is
Its cosmetic job is to condition the scalp and support the appearance of fuller-looking, stronger-looking hair and the look of hair root volume. It uses a light alginate gel base and six actives chosen for their cosmetic roles.
It is not
A drug. It does not treat, prevent, or reverse hair loss. It does not block hormones, stimulate follicles, or affect the structure or function of the body. Those are drug claims and are outside the scope of this product.
