Hair grow average

> Why does my cleint's hair grow the average 1/2 inch on> one side but on the other side it barely grows at all?Hi,There can be many reasons for this happening. Sometimes the hair shaft can be damaged from a fall or accident to the head or scalp.Sometimes this is the result of a genetic pattern related to their hair growth.Also, sometimes there is damage done from chemical processing that damages just one part of the hair and not all of it.Last but not least, sometimes prescription drugs or physical diseases can cause hair not to grow evenly.Hope that helps.Best wishes,Karen
