    TLDR Botanical extracts can protect and repair bleached hair.
    The study investigated the effects of three botanical extracts on chemically damaged hair, specifically hair that had been bleached. The research demonstrated that these botanical actives improved the mechanical properties of the hair, reduced fiber permeability, and increased the crystalline material within the fibers. The botanical treatments, which included proteins and peptides, sulfated polysaccharides, or a combination of polysaccharides, were effective in protecting and repairing hair fibers. This suggested that such botanical extracts could be beneficial in hair cosmetics aimed at repairing and preventing damage from treatments like bleaching and perming.

      community Redensyl for Hair Loss — What It Can and Can’t Do

      in Treatment 2 weeks ago
      Redensyl is a plant-based treatment that may support hair regrowth by reactivating dormant follicles and improving hair density, especially in early-stage thinning. It is not a miracle cure and results vary; it is less proven than Minoxidil or Finasteride and may cause scalp irritation.

      community Nice product I discovered, thought I would share.

      A product that makes hair look thicker and healthier without promoting regrowth. Discussions include treatments like minoxidil, finasteride, red light therapy, and a serum with caffeine and peptides, with mixed effectiveness opinions.

      community Surprisingly thorough study on He-Shou-Wu/Fo Ti

      in Research/Science  14 upvotes 2 years ago
      He Shou Wu (Fo Ti) extract was found to prolong the hair growth phase, inhibit 5-alpha-reductase (like finasteride), reduce androgen receptors, and increase growth factors, potentially outperforming minoxidil in recovering hair follicle size after DHT exposure. Two compounds, emodin and TSG, are identified as responsible for these effects and warrant further investigation.

      community This serum outperformed Minoxidil in a recent study. Please debunk

      A topical solution called "Multi-Peptide Serum for Hair Density" by The Ordinary Company, which contains several ingredients that are used in alternatives to Minoxidil and was found to have better results than 5% Minoxidil in a study. People who have tried it shared their experiences with the serum as well.
