Immunohistochemical Analysis of Tissue Remodeling During the Anagen-Catagen Transition of the Human Hair Follicle

July 1997 in “ British Journal of Dermatology ”

S Commo, Bruno Bernard

anagen phase catagen phase human hair follicles tissue remodeling inner root sheath hair follicle homeostasis monoclonal antibodies

TLDR The inner root sheath is vital for hair follicle stability during growth changes.

The study investigated the transition from the anagen (growth) phase to the catagen (involution) phase in human hair follicles, focusing on tissue remodeling. Using monoclonal antibodies, researchers tracked changes in key hair follicle compartments. They found that the inner root sheath was an early target during the catagen phase, indicating its crucial role in maintaining hair follicle homeostasis.

The treatment for androgenetic alopecia involves using finasteride and minoxidil with intense exercise and cold exposure to boost metabolism and reduce androgenic effects, potentially leading to hair regrowth. This approach may activate biological pathways for improved hair and overall health.

community Weed/THC effects on hair growth/hair loss, and vitality of organ-culture human follicle studies (research review)

in Research/Science 5 upvotes 1 year ago

Cannabis and THC may have mixed effects on hair, with some studies suggesting potential negative impacts on hair growth in isolated hair follicles, but these results are hard to apply to living humans. Treatments like minoxidil and finasteride are commonly used for hair loss, and the effects of cannabis might be neutral or vary based on individual factors.

community Finally, some real breakthroughs. A comparison of the two leading baldness treatments: PP405 versus ABS-201

in Technology 105 upvotes 2 months ago

PP405 and ABS-201 are promising treatments for male pattern baldness. PP405 shows rapid hair growth in human trials, while ABS-201 shows significant regrowth in animal studies but is still in early human trials.

Hair loss treatments discussed include Dutasteride with Ketoconazole, tissue engineering strategies, and androgenetic alopecia therapies. Massage doubles follicular retention, improving treatment effectiveness.

community The Real Cause Of Androgenetic Alopecia

in Research/Science 673 upvotes 1 year ago

Androgenetic alopecia is caused by DHT affecting hair growth. Finasteride and minoxidil are used to manage hair loss by blocking DHT and promoting hair growth.
