In this randomized, controlled trial, the researchers observed that sub-lingual minoxidil at doses of 1.35 mg and 4.05 mg, but not 0.45 mg, significantly increased hair fibre diameter in men with male androgenetic alopecia over 24 weeks, suggesting a dose-dependent reversal of follicle miniaturization.

March 2023 in “Biology” This study identified 2574 differentially expressed genes in the hair follicles of Wan strain Angora rabbits, suggesting that these genes may influence wool fiber diameter and quality.
March 2024 in “International journal of molecular sciences” In this study on Angora rabbits, researchers identified genetic factors influencing wool fiber diameter by analyzing hair follicle proteins, highlighting keratin family members and other proteins as key contributors to fiber differences between coarse and fine wool.
