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.

New treatments for hair growth and psoriasis may be possible, and gene differences could affect baldness and the severity of skin conditions.

Balding scalps show different gene expressions affecting hair growth compared to non-balding scalps.

R-spondin2 may help treat hair loss, gene differences could explain baldness, a peptide's regulation is linked to psoriasis, B-defensin gene copies may affect a skin condition's risk and severity, and potential markers and targets for alopecia areata were identified.

Cells that move well may improve hair loss treatments by entering hair follicles.

New genes found linked to balding, may help develop future treatments.

Hair follicle stem cells help maintain skin health and could improve skin replacement therapies.

Proteins like aPKC and PDGF-AA, substances like adenosine and ATP, and adipose-derived stem cells all play important roles in hair growth and health, and could potentially be used to treat hair loss and skin conditions.

Communication between blood vessel and hair follicle cells decreases with age, affecting hair growth and blood vessel formation.
