Abstract

Hair medulla is a porous structure at the center of the hair, of which little is known, particularly its functions. We have shown that the structure of medulla can be altered by applying and penetrating into the hair, a formulation comprised of a combination of specific components. Such a chemical treatment renders glossiness to the hair making it aesthetically attractive. We call this process “Hair Medulla Care” [1]. We investigated further by assessing the extent of penetrating power of substances in relation to their chemical properties. The results showed that the penetrating power of cationic components enhanced, especially. This finding can be applied to basic hair dyes enabling them to penetrate deeply into the hair, creating deeper and vivid colors. It is hence applicable to a variety of hair care cosmetics including but not limited to hair coloring.
