research Analysis of DNA in Hair Fibers
Small amounts of DNA can be found in the hair shaft, especially near the root, but it decreases with hair treatments and washing.
research A Case of Acquired Trichorrhexis Nodosa After Applying New Hair Spray
New hair spray caused a hair shaft disorder.
research Early and Late Matrix Progenitors Form the Terminally Differentiated Cell Layers of the Hair Follicle
Early and late matrix progenitors in hair follicles create different cell layers, with early ones forming the companion layer and later ones forming the inner root sheath and hair shaft.
research Expression Pattern of mTOR Subunits Raptor and Rictor in Mouse Hair Follicle Cycle
Raptor and Rictor have stable expression in hair cycles, with Raptor marking stem cells and Rictor involved in hair shaft formation.
research WNT Signaling in the Control of Hair Growth and Structure
