Did you mean Epidermal Proliferation?

Glossary Epidermal Proliferation

rapid cell division in skin's outermost layer

Epidermal proliferation refers to the process by which cells in the outermost layer of the skin, known as the epidermis, rapidly divide and multiply. This process is crucial for skin regeneration and repair, helping to replace dead or damaged cells and maintain the skin's protective barrier. In conditions like psoriasis, this proliferation can become excessive, leading to thickened, scaly patches of skin.

community Everything you ever wanted to know about Pelage Pharma's PP405: how it works and what to expect

126 upvotes 3 months ago

PP405 may encourage earlier hair growth and slightly increase visible hair count but does not reverse hair follicle miniaturization in male pattern baldness. It does not address damage to the dermal papilla or broken Wnt signaling.

community Comprehensive Microneedling Guide

292 upvotes 4 years ago

Microneedling for hair restoration involves daily use of a 0.3 mm device and weekly use of a 0.5 mm device. Combining microneedling with Minoxidil can enhance hair growth.

community So we have 20k dollars human like machines available but no new effective treatment for hairloss since finasteride :)

in Chat 237 upvotes 1 year ago

There have been no new effective hair loss treatments since finasteride, despite technological advancements. Current treatments include finasteride, minoxidil, and RU58841, with ongoing challenges and potential future solutions in research.
