Can I use Body hair instead of my scalp hair for a hair transplant?

Body hair can be used but each body hair part has different characteristics that you must be aware of, particularly growth cycle.  Beard hair is similar to scalp hair in its growth cycle with a long Anagen phase and a short telogen phase. It is, however, more curly and course possibly than your scalp hair.  Arm, chest, and leg hair has a very short Anagen phase and a long telogen phase which means that much of the hair will not grow longer than 6-8 months and ‘sleep’ for 5-6 months so its value will be less in terms of length. These hairs are also finer and often do not have the appearance of normal scalp hair when they grow out. ?Pubic hair of course looks like pubic hair but works well as does underarm hair with its sweat glands.
