ELSEWHERE IN THE WORLD

It is quite obvious that no particular ethnic group has any advantages when it comes to hair. On the other hand, each group can be associated with a certain type of hair, easily identifiable by its colour and form, but also by something less obvious to the naked eye - the way it grows.

Classifying hair into no more than three ethnic types - African hair, Asianhair, or Caucasian hair - might seem an exaggerated simplification. But it is true that Japanese hair is not the same as Indonesian hair and, even more obvious, Scottish hair has no resemblance to Swedish hair or Sicilian hair. However, these are only small differences in comparison with the similarities that each ethnic group has in general terms. Whether it is a question of the hair's density, speed of growth or the implantation of the hair follicle in the scalp, we can consider that each of the ethnic types mentioned above has its own identity.


  Asian hair

For example, Asian hair holds the speed record for growth with 1.3 cm a month. On the other hand, it has lower density than any of the other ethnic groups. The way its follicle is implanted causes the hair to grow straight, perpendicular to the scalp.

  African hair

African hair, generally black hair, is the slowest growing of all, at less than 0.9 cm a month. On the other hand it is slightly more dense than Asian hair and grows almost parallel to the scalp, twisting around itself as it grows.

  Caucasian hair

As far as rate of growth is concerned, Caucasian hair comes between the other two at 1.2 cm a month, but it has the highest density of all. It grows at an oblique angle to the scalp and is slightly curved.
