Q: What happens to hair diameter when you age?

A: From infancy to puberty, hair gets progressively thicker. From adulthood to old age the hair becomes thinner again and this is exacerbated by the effects of DTH in susceptible persons. The later process is called androgenetic alopecia (common baldness) and is characterized by miniaturization – the progressive decrease in hair diameter and lengths as a result of DHT.

However, even without the effects of DHT, hair gradually thins over time in many people.

Q: What color hair is the thickest? I thought it was brown, followed by red then blonde? But I am also reading that red is the thickest but redheads have the fewest hairs.

A: In very general terms, the darker the hair, the thicker it is and the lower the density (hairs per area). For example, Asians have the darkest hair, the highest hair diameter and the lowest density. Scandinavian blonds have very high hair density and the fine (diameter) hair. But there are many exceptions, African Americans have black hair, but it is usually very fine and of low density. I have seen red heads in all categories.
