Hair has many useful biologic functions, including protection from the elements and dispersion of sweat-gland products (e.g., pheromones). It also has psychosocial importance in our society, and patients with hair loss (alopecia) (Table 1) or excessive hair growth often suffer tremendously.

AbstractFour cases of hair follicle nevi are described. Hair follicle nevus is an extremely rare hamartoma occurring on the face, which has had no clear histopathologic definition until now. A short review of the clinicopathologic features of this disease is presented.

Embryology of the hair follicle
Early Human Development, 1991A study of hair follicle development has enabled us to differentiate four stages by relating them to corresponding gestation ages. Stage I of the hair bud is characterized by an epiblastic proliferation penetrating the subjacent mesenchyma at the extremity of which mesenchymal cells accumulate.

A case of a 5-year-old child with a rare nevus of a hair follicle is reported. Histologically it was characterized by many hair follicles within the dermis at the same level of maturation. This nevus must be differentiated from other hamartomas of hair follicles and from Becker's nevus.

Melatonin and the hair follicle
Journal of Pineal Research, 2007Abstract:âMelatonin, the chief secretory product of the pineal gland, has long been known to modulate hair growth, pigmentation and/or molting in many species, presumably as a key neuroendocrine regulator that couples coat phenotype and function to photoperiodâdependent environmental and reproductive changes.

It is fashionable to refer to man as a naked ape, meaning a hairless ape. This witty designation, however, is completely wrong, since we are certainly not hairless and we are not apes. We are abundantly supplied with hairs, but most of them are barely visible to the naked eye. Quantitatively, we probably have as many hairs in our skin as furry animals.

Hair follicle predetermination
Journal of Cell Science, 2001Recent genetic and molecular studies of hair follicle (HF) biology have provided substantial insight; however, the molecular data, including expression patterns, cannot be properly appreciated without an understanding of the basic cellular rearrangements and interactions that underpin HF cyclic transformations.

Hair Follicle Regeneration by Transplantation of a Bioengineered Hair Follicle Germ
2016Hair follicle morphogenesis is first induced by epithelial-mesenchymal interactions in the developing embryo. In the hair follicle, various stem-cell populations are maintained in specialized niches to promote repetitive hair follicle-morphogenesis, which is observed in the variable lower region of the hair follicle as a postnatal hair cycle.
