    GlossaryHair Growth (Hair Elongation)

    process where hair strands develop from follicles in the skin

    Hair growth refers to the process by which hair strands develop from hair follicles located in the skin. This process involves three main phases: anagen (growth phase), catagen (transitional phase), and telogen (resting phase). During the anagen phase, cells in the hair bulb divide rapidly, adding to the hair shaft and causing it to lengthen. Factors such as genetics, hormones, and overall health can influence the rate and quality of hair growth.

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

      in Research/Science  4 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.
