research Smad7-Induced β-Catenin Degradation Alters Epidermal Appendage Development 147 citations , September 2006 in “Developmental Cell” Too much Smad7 changes skin and hair development by breaking down a protein called β-catenin, leading to more oil glands and fewer hair follicles.
research Sinapic acid and glabridin synergistically mitigate androgenetic alopecia by modulating ferroptosis through stabilization of β-catenin against ubiquitin-dependent degradation. July 2025 in “PubMed” Sinapic acid and glabridin together help hair growth in androgenetic alopecia.
research Retinoids in scarless skin regeneration: from molecular mechanisms to therapeutic strategies September 2025 in “Frontiers in Cell and Developmental Biology” Retinoic acid may help heal skin without scars by reducing fibrosis and supporting skin regeneration.
research The Role of Smads in Skin Development 59 citations , March 2008 in “The journal of investigative dermatology/Journal of investigative dermatology” Smad-4 and Smad-7 are key in hair follicle development, with other Smads being less important.
research Terminalia chebula retz. Fruit Extract Promotes Murine Hair Growth by Suppressing 5α-Reductase and Accelerating the Degradation of Dihydrotestosterone October 2025 in “Biomedicines” Terminalia chebula fruit extract helps hair growth by reducing DHT and boosting hair cell activity.
