Question: Can your hair grow if its dead?

Why does hair grow if it’s dead?

Once the heart stops pumping oxygen round the body in the blood, the energy supply dries up, and so does the cell division that drives hair growth.

Can dead hair cells fully grow back?

To date, research shows that mammalian cochlear hair cells do not regenerate, either spontaneously or after damage. However, lower vertebrates (fishes, amphibians, reptiles, and birds) can spontaneously regrow hair cells, under normal conditions and/or after damage. Hair cell regeneration allows birds to hear again.

What happens if hair cells are damaged?

In humans and other mammals, any damage that results in hair cell death can lead to irreparable hearing loss due to the inability of mature mammalian hair cells to regenerate [10]. In contrast, the hair cells of many non-mammalian vertebrates, such as birds and amphibians, have a significant regenerative capacity [11].
