180-210 / 1000+ resultsresearch X-rays studies of the structure of hair, wool, and related fibres. II. - The molecular structure and elastic properties of hair keratin
Stretched hair has a similar structure to natural silk, showing hair's elasticity involves reversible changes within its molecules.
research Epithelial skirt and bulge of human facial vellus hair follicles and and associated Merkel cell-nerve complex
Merkel cells are abundant in facial vellus hair follicles, especially during the anagen phase.
research The three-dimensional microvascular and collagen fibrillar arrangements around rat vibrissa hairs as revealed by scanning electron microscopy
The lower part of rat vibrissa hair gets more blood and is well-protected for growth.
research Morphology and Properties of Hair
Hair is made of strong keratin fibers that protect against the environment.
research Identification of Ectodysplasin Target Genes Reveals the Involvement of Chemokines in Hair Development
Chemokine signaling is important for hair development.

Epidermal growth factor (EGF) boosts hair follicle growth and speeds up hair cycle transition.
research In-Situ Tensile Testing of Hair Fibers in An Environmental Scanning Electron Microscope (ESEM)
Hair fibers break by cuticle cell slipping, shape changing, cuticle fraying, and surface cracking when stretched under specific conditions.
research Human hair follicles are an extrarenal source and a nonhematopoietic target of erythropoietin
Human hair follicles produce and respond to erythropoietin, helping protect against stress.
