Understanding Hair Follicle Biology
Why Hair Follicles Stop Growing
Hair loss, particularly androgenetic alopecia (male and female pattern baldness), involves multiple biological failures happening simultaneously. Your hair follicles exist in a delicate ecosystem that requires constant signaling, growth factor support, and blood supply to thrive.
In androgenetic alopecia, several things go wrong at once. First, DHT sensitivity causes genetically predisposed follicles to shrink - a process called miniaturization. The hair gets thinner and shorter with each growth cycle. Second, growth factor deficiency means the follicles aren't getting the molecular signals they need to stay active. Third, inflammation and oxidative stress damage the hair follicle stem cells that are supposed to regenerate new hair.
"Your hair follicles are receiving fewer growth signals and more damage signals."
Peptide therapy addresses this from multiple angles - some provide direct growth factor signaling, others reduce inflammation, some stimulate new blood vessel formation, and others enhance the follicle's own repair mechanisms. Different peptides attack the problem in different ways.
