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.

The study maps goat hair follicle cells, revealing key genes and pathways involved in hair growth and cell death.

Different types of inactive melanocyte stem cells exist with unique characteristics and potential to develop into other cells.

Skin healing from blisters can delay hair growth as stem cells focus on repairing skin over developing hair.

The hydrogels help harvest cells while preserving their mechanical memory, which could improve wound healing.
