Hair Weathering And Hair Capacitance Mapping: A Pilot Study

    TLDR Hair capacitance mapping effectively measures hair surface moisture changes.
    The study introduced a new method called hair capacitance mapping (HCM) to assess hair surface damage and hydration. Conducted on both intact and weathered hair locks, the research involved soaking samples in 10% solutions of regular shampoos or tap water. The HCM method, utilizing the SkinChip® device, revealed that hair surface moisture increased for less than 30 minutes after soaking. It also detected a moisture gradient from the base to the tip of hair shafts, with weathered hairs losing moisture more rapidly than intact ones. The study concluded that HCM was a promising technique for evaluating the dynamics of hair surface moisture.

      community if hair follicle miniaturization happens slowly and gradually over a few hair cycles then wouldn't that mean that to regain maximum or top thickness from treatment you would at least need 5-10 years?

      Hair regrowth from treatments like finasteride, dutasteride, and minoxidil can take several years, with most visible results appearing within 1-2 years and potential improvements continuing up to 10 years. Consistency and patience are crucial for achieving maximum hair thickness, as hair miniaturization and regrowth are gradual processes.

      Hair fibers can effectively cover thinning hair when used with minoxidil and hairspray but require daily application and can be inconvenient in certain conditions. Some users prefer treatments like finasteride, dutasteride, microneedling, or wigs due to the maintenance and limitations of hair fibers.
