Hair loss because of stem cells?
Last February 2016, a study of Science that published about when people get age, the hair follicle stem cells in the scalp gather mutations and the follicles themselves will shrink.
When women ages with 22 -10 years old had more mutations and their follicles are smaller than those younger women.
Last February 2016, If they can meddle with that factor, or remove that factor from the stem cell, they can shorten those dormant stages and rather inducing those cells to keep separating and stimulating for hair development.
In the meantime, a group researchers found that the hair follicle stem cells go temporarily inactive.
However, deleting the genes for the Foxc1 protein can maintain to avoid a strategic distance from such dormant.
