thyroid hormone receptors TRα1 TRβ keratinocyte proliferation hair follicles anagen phase alopecia re-epithelialization thyroid hormones hair growth skin repair

TLDR Thyroid hormone receptors are essential for hair growth and wound healing.

The study demonstrated that mice lacking thyroid hormone receptors (TRα1 and TRβ) exhibited impaired hair growth and delayed wound healing. These mice showed reduced keratinocyte proliferation in hair follicles, fewer anagen phases, and developed alopecia after repeated depilation. Additionally, they experienced slower re-epithelialization and reduced keratinocyte proliferation during wound healing. The findings indicated that thyroid hormones, through their receptors, played a crucial role in hair growth and skin repair, suggesting potential therapeutic targets for skin-related conditions.

community Diffuse hair loss and scalp biopsies

in Research 692 upvotes 3 months 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.

community Why does finasteride stop working?

in Finasteride/Dutasteride 26 upvotes 1 month ago

Finasteride may seem less effective over time due to increased DHT sensitivity or aging, but it still suppresses DHT. Switching to dutasteride offers stronger DHT suppression but may increase estrogen levels.
