    GlossaryHair Diameter (hair caliber)

    width of an individual hair strand, measured in micrometers

    Hair Diameter, also known as hair shaft diameter or hair thickness, refers to the width of an individual strand of hair. It is typically measured in micrometers (µm) and can vary significantly among individuals and even among different hairs on the same person. This measurement is important for understanding hair texture, strength, and overall health, and it can influence how hair responds to styling and treatment products.

      community Topical Dutasteride Seems to Work

      in Research/Science  22 upvotes 3 months ago
      Topical dutasteride, particularly at 0.05%, shows greater hair density improvement than oral finasteride over 24 weeks, though hair thickness gains are similar. Some users report side effects with topical treatments, but others find them effective for maintaining hair without significant systemic absorption.

      in Minoxidil  73 upvotes 4 years ago
      Oral minoxidil treatment increased hair density and shaft caliber in AGA patients. Side effects included hypertrichosis and lower extremity edema, with younger patients experiencing fewer side effects.

      community Occipitalis Muscle Tension Theory

      in Treatment  7 upvotes 1 week ago
      Scalp tension from the occipitalis muscle is theorized to contribute to hair loss, but most believe DHT and genetics are the main causes. Treatments like finasteride and minoxidil are considered more effective than addressing scalp tension.

      community Peppermint oil for Hair Thickness

      in Research/Science  2 upvotes 2 months ago
      Peppermint oil may increase hair thickness more effectively than minoxidil, but its effects are mostly studied in animals. Users report mixed results, with some seeing no regrowth and others noting slight improvements when combined with other treatments.
