substance P hair growth organ culture method hair follicles proliferation

TLDR Substance P helps hair grow longer and faster.

The study investigated the role of substance P (SP) on human hair growth using an organ culture method. It was found that SP prolonged the duration of hair growth and increased the rate of linear hair growth. This suggested that SP might play a significant role in the physiology of hair follicles by promoting their proliferation. The findings provided insights into the potential of SP as a therapeutic target for hair growth regulation.

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.
