    GlossaryCatagen Phase (CAT)

    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 Is it true that most hair loss treatments fall into one of two categories? If not, what am I missing?

      in Treatment  4 upvotes 8 months ago
      Hair loss treatments are generally categorized as anti-androgens, like finasteride and RU58841, which prevent hair loss by targeting DHT, and growth stimulators, such as minoxidil, rosemary oil, microneedling, and LLLT, which promote hair growth by increasing blood flow and growth factors. The user is seeking to confirm these categories and understand if there are other treatments or mechanisms of action.
