Hair is the fastest growing tissue in the body, second only to bone marrow.
35 metres of hair fibre is produced every day on the average adult scalp.
The average scalp has 100,000 hairs. Redheads have the least at 80,000 brown and black haired persons have about 100,000; and blondes have the most at 120,000.
90% of scalp hairs are growing and 10% are resting.
It is normal to lose 100 hairs per day from the scalp.
