High-resolution MRI can distinguish between tertiary androgenetic alopecia and severe alopecia areata by measuring scalp and tissue thickness and hair follicle depth.

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.

Thymosin β4 helps improve skin healing and reduce scarring.

Large-scale fibronectin nanofibers help heal wounds and repair tissue in a skin model of a mouse.
