There is no
part of human body that is not mind captivating and today interest is on human
hair. In Kenya demand for human hair extensions by ladies just hit the roof. Dreadlocks
are also selling like blue chip shares in a stock exchange market according to local press, but
that aside.

Human hair
grows about 13cm per year, but that varies with race. This means it grows about
0.35mm per day. According to a 2005 study by the researchers of International
Journal of Dermatology, hair growth varies with human race, though. For Asians,
hair grows about 15cm per year (6 inches); Caucasians have theirs grow at the
rate of 13cm and Africans’ at 10cm per year. Research showed that there was no
significant difference in the rates of growth in male participants compared to
their female counterparts.

Researchers
have the notion the dietary changes and seasons determine hair growth as well. For
example, hair is said to grow quicker in summer due to escalated levels of Ultraviolet
radiation exposure, shifts in hormones and eating of more vegetables and fruits.
A
trichologist (hair and scalp dermatologist) from New York, Elizabeth
Cunnane-Phillips says that increments in hair growth per given season is too
marginal to notice.
