The final type of notable human hair is the vellus hair that covers our bodies.

最后一种值得一提的人类发覆盖我们身体的毳。

We don't know if these hairs serve any purpose themselves, but the follicles vellus hair grows from are essential banks of stem cells that repair damaged skin after injury.

我们知道毳有任何用途，但从长出毳的囊重要的干细胞库，能修复受伤的皮肤。

This results in the loss of so called 'terminal' adult hair and the production of much finer 'vellus' hairs – like those on the heads of babies.

这会导致所谓的“终末”成人发脱落，并长出更细的“毫”——就像婴儿头上的发一样。
