    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.

      community Do hair follicles dies or are dormant ?

      in Finasteride/Dutasteride  92 upvotes 2 months ago
      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.
