research Proliferating trichilemmal cyst with histological malignant transformation: Identification of hair sheath keratins in the tumor.
A hair cyst can become cancerous, showing specific keratins from the hair sheath.
research Methotrexate
Long-term use of minoxidil may cause hair follicles to transform into noticeable terminal hairs, leading to trichostasis spinulosa.
research 862 Defining the molecular signature of the hair follicle dermal sheath and its functional requirement for hair cycle progression during catagen
The hair follicle dermal sheath is essential for hair shedding and needs to communicate with the outer root sheath for normal hair growth cycles.
research The Art of Mixing Follicular Units and Follicular Groupings in Hair Restoration Surgery
Mixing different sizes of hair follicles during hair restoration surgery can give excellent results, save time, and cause less damage.
research Structural interspecies variability of mammals' hairs
