    TLDR Rosemary-based gel with metformin may effectively treat hair loss like minoxidil.
    The study investigates a rosemary-based nanoemulgel loaded with metformin for managing androgenetic alopecia (AGA), using a formulation optimized for effective drug delivery and minimal side effects. Tested on 50 Wistar albino rats, the metformin-loaded nanoemulgel showed promising hair growth effects comparable to minoxidil, with histopathological examination confirming hair follicle growth and skin tolerability. The nanoemulsion achieved a uniform particle size, high entrapment efficiency, and maintained metformin's chemical integrity, suggesting improved drug delivery. This formulation could be a safer, effective alternative to minoxidil, leveraging the synergistic effects of rosemary oil and metformin for alopecia treatment.

      community Rosemary oil's potency as a dht blocker

      in Research/Science  65 upvotes 1 year ago
      Rosemary extract showed high inhibitory activity against DHT, similar to finasteride and dutasteride, but the conversation includes skepticism about its effectiveness in humans since the study was done on mice and rosemary oil is often considered ineffective based on personal experiences. Some suggest trying rosemary oil alongside other treatments, while others emphasize the difference between the extract used in the study and the oil.
