Do grey hairs grow faster?
Although there many myths surrounding grey hair, this answer seems to be yes!
Dr Van Neste examined 3343 hairs from 24 women. Grey hairs not only seemed to grow faster, but were also thicker than standard pigmented hair. Thicker hairs were thought to be due to the more developed central layer of the hair known as the medulla.
