Does thick hair become thinner after puberty?

Yes, thick hair can become thinner after puberty. During puberty, the body undergoes significant hormonal changes that can affect hair growth. The increase in testosterone levels in both boys and girls can lead to a change in hair texture, with thick hair becoming thinner and finer. This is because the increased testosterone can cause the hair follicles to shrink and produce thinner hair shafts. Additionally, the increased production of sebum, the natural oil produced by the scalp, can also contribute to hair thinning as it can clog the hair follicles and prevent new hair from growing.
