LGR5 is a common marker of hair follicle stem cells in different animals and is important for hair growth and regeneration.

Hair loss in Androgenetic alopecia (AGA) is due to altered cell sensitivity to hormones, not increased hormone levels. Hair growth periods shorten over time, causing hair to become thinner and shorter. This is linked to miscommunication between cell pathways in hair follicles. There's also a change in gene expression related to blood vessels and cell growth in balding hair follicles. The exact molecular causes of AGA are still unclear.

Certain natural products may help stimulate hair growth by affecting stem cell activity in the scalp.

Tiny particles from stem cells help activate hair growth cells and encourage hair growth in mice without being toxic.
