Since long I have been thinking of writing about the part ethnicity plays in hair types. In my last post I discussed the anatomy of hair. So it is quite natural that I write about different factors affecting the hair especially head hair.
Caucasoid hair
Asian hair
African hair
Reason behind ethnic hair differences
• Different hair shaft types which are produced by the hair follicles. Large, straight hair follicles with a circular cross section results in thick, straight hair shafts. Curly, flat hair follicles create curly elliptical or ribbon shaped cross section hair fibers.
• The shape of the hair follicle acts as a mold for the creation of the hair fiber or shaft. Different the shape of the mold, different is the shape of the hair. The newly produced cells take the shape of the hair follicle root sheaths as soon as they are attached to it.
• The difference in the fiber characteristics might be result of difference in the chemical composition of hair in different ethnic groups, but while some studies have pointed to a difference in chemical composition this theory still needs to be proved by conclusive studies.
Whatever are the reasons for differences in the hair, it is of importance for all to take specialized care of their hair by good nutrition or supplements and only by special hair care products.
