research Dermal Wnt/β-Catenin Activation Tunably Controls Hair Follicle Initiation
Activating Wnt in skin cells controls the number of hair follicles by directing cell movement and fate.
research The De Novo DNA Methyltransferase DNMT3A Is Required for Epidermal Homeostasis
DNMT3A is crucial for healthy skin and hair growth.
research Mature Adipocytes Inhibit the Antimicrobial Function of Dermal Adipogenic Stem Cells: An Explanation for Impaired Cutaneous Defense in Obesity
Obesity can weaken the skin's ability to fight infections because fat cells stop and reduce the infection-fighting properties of nearby stem cells.
research Beyond Goosebumps: Interactions Between the Hair Follicle, the Arrector Pili Muscle, and the Sympathetic Nerve During Development and Hair Follicle Regeneration
Arrector pili muscle regulates hair follicle stem cells, DNA methylation needed for hair cycling, and Wnt/B-catenin signaling starts hair growth.

community Diffuse hair loss and scalp biopsies
Scalp biopsies are crucial for diagnosing hair loss conditions like Diffuse Unpatterned Alopecia (DUPA) and retrograde hair loss, as treatments like finasteride and dutasteride may not be effective if other conditions are present. Combining PPAR-GAMMA agonists with retinoids could improve treatments for conditions like Lichen Planopilaris.
