epidermis hair follicle development epithelium mesenchyme hair follicle induction

TLDR The epidermis is crucial for hair growth.

The document discussed the critical role of interactions between the epithelium and mesenchyme in hair follicle development, emphasizing that both components must respond appropriately for growth to proceed. While much research had focused on the inductive properties of mesenchymal cells, this commentary highlighted the importance of the epidermis in hair follicle induction.

community Compressed part of research of theory of androgenic/anabolitic balance. AGA h-responders analytic. Theory of physio-metabolitic method of anti AGA treatment

in Research 865 upvotes 10 months ago

The treatment for androgenetic alopecia involves using finasteride and minoxidil with intense exercise and cold exposure to boost metabolism and reduce androgenic effects, potentially leading to hair regrowth. This approach may activate biological pathways for improved hair and overall health.

community If You Have DUPA, PLEASE READ THIS: Everyone Should Be Scalp Biopsied

in Research 830 upvotes 1 year ago

Scalp biopsies are crucial for diagnosing hair loss conditions like Diffuse Unpatterned Alopecia (DUPA) and retrograde hair loss, as treatments like finasteride and dutasteride may not be effective if other conditions are present. Combining PPAR-GAMMA agonists with retinoids could improve treatments for conditions like Lichen Planopilaris.
