    GlossaryCatagen Phase (catagen follicles)

    hair growth stops and follicles shrink, lasting about 2-3 weeks

    The Catagen Phase, also known as the Transitional Phase, is a short period in the hair growth cycle that lasts about 2-3 weeks. During this phase, hair growth stops, and the hair follicle shrinks and detaches from the dermal papilla, effectively transitioning the hair from the growth phase (Anagen) to the resting phase (Telogen). This phase is crucial for the renewal of hair follicles and the overall hair growth process.

      Hair follicles can be dormant and potentially revived with treatments like finasteride and minoxidil, but irreversible loss occurs if certain structures are destroyed. Early intervention is more effective, and additional methods like microneedling may help.

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

      in Research/Science  4 upvotes 7 months 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.
