So-called "Ethnic" treatments are addressed to two types of population. Firstly phototype V and VI populations who are mixed-race and colored, and secondly phototype III and IV populations who are Asian. Although apart from pigmentation the structural differences between these two types of skin (and skin in general) are not marked, the requirements of the two types are different.
1) Colored and mixed-race skin has been known to be dry and irritated. They require intense moisturization. Desquamation is 2.5 times higher than that of Caucasian skin, which leads to the skin having a gray, dusty appearance. Body treatments are as important as face treatments. Another consideration might be the preference of using makeup or not.. Finally, in spite of the risks that they run, the use of depigmenting products is still unavoidable.
Black hair is typically tight-curled, thin, has an oval cross-section and dry. Sebum only flows with difficulty along the fibers, which are not rectilinear.The hair is therefore dry, porous and breaks easily.
