    Glossary Hair Miniaturization

    hair follicles shrink, producing thinner and shorter hair strands

    Hair miniaturization is a process where hair follicles shrink over time, producing thinner, shorter, and less pigmented hair strands. This phenomenon is commonly associated with androgenetic alopecia (pattern baldness) and can eventually lead to the follicles becoming dormant and ceasing to produce hair altogether.
