research Facial Follicular Spicules: A Rare Cutaneous Presentation of Trichodysplasia Spinulosa
Trichodysplasia spinulosa can occur after a heart transplant due to immunosuppressive drugs.
research The role of activins and follistatins in skin and hair follicle development and function
Activins and follistatins, part of the TGFβ family, are crucial for hair follicle development and skin health, affecting growth, repair, and the hair cycle.
research Biomechanics of hair fibre growth: A multi-scale modeling approach
The model shows that factors like follicle shape and stiffness are key for hair growth and anchoring.
research Hair Follicle Culture
Hair follicle culture helps study hair growth but has limitations in modeling the full hair cycle.
research Inducing hair follicle neogenesis by defined extracellular factors
Certain factors can start hair growth in adult skin by making cells communicate and form new hair follicles.
research 1322 A non-cell autonomous dermal hedgehog signaling mechanism for follicular neoplasia and induction
Mutations in the SHH pathway in certain skin cells can cause skin tumors and abnormal hair growth.
research 5a Trichoepithelioma
Trichoepithelioma and desmoplastic trichoepithelioma have distinct features that can be identified using reflectance confocal microscopy.
research The mineralization of hair follicle tissue
Hair follicle tissue can induce mineral formation, likely due to a potent nucleator.

research Hair Follicle Miniaturization in a Woolly Hair Nevus
The boy with woolly hair nevus had thinner hair and abnormal hair follicles, which improved with treatment but worsened when treatment stopped.
research The enhancement of dermal papilla cell aggregation by extracellular matrix proteins through effects on cell–substratum adhesivity and cell motility
Skin cell clumping for hair growth is improved by a protein called fibronectin, which helps cells stick and move better.
research Hair-follicle dermal papilla and sheath fibroblasts provide a supportive microenvironment for human skin regeneration
Certain cells around hair follicles help improve skin regeneration for potential use in skin grafts.
research Trichofolliculoma with swelling of the upper lip and oral vestibule
A benign hair follicle tumor caused upper lip swelling, was removed, and did not return.
research Unusual dermoscopic features in a patient with alopecia areata
Alopecia areata can show unusual red-dotted vessels and dithranol treatment may mask typical patterns.
