TLDR Mineral deposits form in hair follicles after skin injury, faster in rats given DHT.
The study investigated the mineralization of hair follicle tissue in hyperealeaemic rats following skin injury. It was found that mineral deposits, indicated by increased calcium and phosphorus, began forming in hair follicle tissue 6-12 hours after a mild crush injury in rats dosed with dihydrotachysterol (DHT), and 24-48 hours in non-dosed rats. X-ray diffraction showed a diffuse apatite pattern. Additionally, a rise in calcium content was observed within 3 hours of injury, likely due to calcium binding rather than mineral deposition, and was not related to DHT dosing.
