Did you mean Fibroblast Activity?

GlossaryFibroblast Activity

production of collagen and extracellular matrix by connective tissue cells

Fibroblast activity refers to the behavior and function of fibroblasts, which are specialized cells in connective tissue that produce collagen and other extracellular matrix components. These cells play a crucial role in wound healing, tissue repair, and maintaining the structural integrity of tissues. Enhanced fibroblast activity can lead to improved skin health and hair growth, while impaired activity may contribute to conditions like scarring or alopecia.

community REVOLUTION in AUGUST: New possibilities according to Dr. Muñoz (pinacidil, cromakalim, diazoxide and nicorandil)

in Technology 13 upvotes 10 months ago

Dr. Muñoz's discovery suggests that targeting potassium channels in fibroblasts could reactivate hair growth, offering new treatment possibilities for alopecia. Potential strategies include using minoxidil, diazoxide, and other potassium channel openers, as well as bioelectric devices and direct growth factor applications.

community Topical Finasteride Doesn't Directly Reduce 5ar Enzyme on Scalp

in Finasteride/Dutasteride 72 upvotes 3 years ago

Topical Finasteride doesn't directly reduce 5ar enzyme on scalp and has the same mechanism as oral, needing to go through the liver. Users debate the accuracy of this information and discuss various studies and experiences.

community Looks like a real cure to the root of baldness (DHT-induced senescence) was proven earlier this year

in Research/Science 739 upvotes 3 years ago

A study that outlines the full model for androgenic alopecia (AGA) which links DHT to cellular senescence in dermal papilla cells, and suggests black chokeberry as a source of cyanidin 3-O-arabinoside polyphenol with potential anti-oxidant properties that could reverse this process. The post encourages reaching out to experts in anti-aging and longevity to research treatments involving the polyphenol.

community Reducing Fibrosis in Hair Loss: Topical Pirfenidone

in Research/Science 58 upvotes 4 months ago

Topical pirfenidone is highlighted as an effective anti-inflammatory and anti-fibrotic treatment for hair loss, particularly in addressing perifollicular fibrosis, which may enhance the effectiveness of standard treatments like finasteride and minoxidil. The user also uses calcipotriol, MCT oil, ciclopirox shampoo, and benzoyl peroxide shampoo as part of their regimen.
