Healthier Hair in 4 minutes¹
¹healthy hair - We define healthy hair as hair that exhibits a combination of strength, elasticity, manageability, softness, smoothness, vibrancy, shine and is frizz free' but note that we’re not providing data as substantiation against each of the descriptors where we make healthy hair claims. This also doesn't describe 'healthiest'.
