This study reports that some patients with androgenetic alopecia may also exhibit clinical and histological features of inflammation and fibrosis, similar to those found in lichen planopilaris.
In this animal study, the researchers found that biodegradable extracellular matrix scaffolds accelerated wound healing and enhanced hairfollicle neogenesis in mice, suggesting a role for immune systems in tissue regeneration.

This study demonstrated that a bio-3D printed artificial skin scaffold, seeded with adipose-derived mesenchymal stem cells, showed promising wound healing properties by enhancing cell recruitment, migration, and gene expression related to tissue regeneration.

This research found that a biodegradable fibrous membrane incorporating fibroblast-derived ECM accelerated wound healing and improved neovascularization in a mouse model.
This research suggests that plucked hairfollicles may serve as a reliable surrogate tissue for tumor biopsies in drug development, based on a mouse model linking hair and tumor pharmacodynamic responses.
Hairfollicles are mostly dormant but can be reactivated with treatments like minoxidil, finasteride, and microneedling. A new drug, PP405, shows promise for hair regrowth but may not be available until 2027-2028.
PP405 is ineffective for miniaturized, fibrosed hairfollicles in androgenetic alopecia. AMP303 may activate hairfollicle stem cells, but minoxidil and finasteride are still the main treatments.
DHT is not the only cause of male pattern hair loss; genetic sensitivity, inflammation, and fibrosis also contribute. GHK-Cu, a copper peptide, is being explored as an alternative treatment to finasteride and minoxidil, showing potential in improving follicle health.
High sugar diets may worsen hair loss by increasing 5α-reductase activity and androgen levels, especially in women with PCOS. A low sugar diet might reduce scalp DHT levels, similar to finasteride, but genetics also significantly influence hair loss.
