compound follicle structures folliculitis decalvans terminal anagen follicles vellus follicles telogen follicles

TLDR Compound follicles in folliculitis decalvans mainly have active hair follicles.

The study investigates compound follicle structures (CFS) in folliculitis decalvans (FD) and finds that these structures are primarily composed of terminal anagen follicles, rather than vellus or retained telogen follicles. This finding may contribute to a better understanding of the disease mechanism in FD.

in Research/Science 74 upvotes 1 year ago

Peptides like TB500, KPV, GHK-CU, and BPC-157 are overhyped for hair growth with limited proven effectiveness in humans. Combining peptides with delivery methods like iontophoresis and sonophoresis shows promise, but many claims remain unproven.

community Don't use PP405 from everychem. it is likely fake.

in Research/Science 64 upvotes 8 months ago

PP405 from Everychem is likely fake and potentially harmful, with concerns about its stability and the risk of using the wrong MPC inhibitor, which could damage hair follicles. The real PP405 was studied under strict conditions, and DIY attempts are discouraged due to unknown formulation and quality control.
