White hairs often regrow in alopecia areata patches.

Intense pulsed light treatment mainly damages pigmented hair parts but spares stem cells, allowing hair to regrow.

Putting thymidine dinucleotide on newborn mice's skin can delay and reduce skin cancer.

The conclusion is that Pigmented Epithelioid Melanocytoma can start from hair follicle stem cells or from a mole on the skin.

Reflectance spectroscopy can noninvasively track hair growth stages by measuring skin reflectance and melanin changes.

Good nutrition may help prevent premature hair graying.

Eating a balanced diet with the right vitamins and minerals is important for healthy hair, but too many supplements can be harmful.

The Hair Implanter Pen increases speed and is gentle on grafts, with users mastering it after a few tries.
