Chest hair as a source for hair transplant hair

How many chest hair grafts does the average male have that can be obtained from their chest and what is the survival rate?

Chest hair can be used for hair transplant as a donor source; however, it is not the best hair because (1) it has a short anagen cycle and a long telogen cycle, which means that only about half of the hairs will be growing at any one time, (2) the hair is finer than scalp hair most of the time, (3) chest hair grows as single hairs so a graft requires two or three grafts put together for a reasonable graft value. If the surgeon charges per graft extracted, that makes chest hair three times the cost of scalp or beard hair.  The hair usually falls out within days or weeks after the start of the telogen cycle.
