    TLDR Low-molecular weight hyaluronate can make damaged hair stronger.
    The study found that low-molecular weight hyaluronate (low-MW HA) significantly improved the mechanical properties of over-bleached hair by enhancing tensile strength and elastic modulus by nearly 16%. Low-MW HA penetrated deep into the hair cortex, forming additional intermolecular hydrogen bonds within hair keratin, and improved water bonding, which contributed to the enhanced mechanical properties. This highlights the potential of low-MW HA in hair damage repair and its application in hair care products.

      The conversation discusses using estradiol mesotherapy to replicate hormone replacement therapy results while minimizing systemic exposure. It also covers the use of Spironolactone cream, which reportedly has no systemic side effects, and the potential risks of using bicalutamide and Spironolactone in men.

      community Topical Finasteride strength discussion

      in Research/Science  65 upvotes 1 year ago
      The conversation discusses the effectiveness of different concentrations and dosages of topical finasteride on scalp and serum DHT levels, comparing it to oral finasteride and noting the side effects seem to be fewer at lower dosages. Participants shared experiences and referenced a chart indicating similar scalp DHT reduction with 0.025% topical finasteride as with 1mg oral finasteride, but with fewer side effects.
