The cyclical phases of growth (anagen), regression (catagen), quiescence (telogen), and shedding (exogen) in the life of a hair; one of the collection or mass of filaments growing from the skin of an animal, and forming a covering for a part of the head or for any part or the whole of the body. The developmental process by which a hair placode forms. An hair follicle placode is a thickening of the ectoderm that will give rise to the hair follicle bud. The process whose specific outcome is the progression of the ectoderm over time, from its formation to the mature structure. In animal embryos, the ectoderm is the outer germ layer of the embryo, formed during gastrulation. A multicellular organismal process involved in the periodic casting off and regeneration of an outer covering of cuticle, feathers, hair, horns, skin. A multicellular organismal process involved in the cyclical phases of growth (anagen), regression (catagen), quiescence (telogen), and shedding (exogen) in the life of a hair; one of the collection or mass of filaments growing from the skin of an animal, and forming a covering for a part of the head or for any part or the whole of the body. The process by which the anatomical structures of the hair follicle are generated and organized. Any process that activates or increases the frequency, rate or extent of hair follicle development. Any process that stops, prevents or reduces the frequency, rate or extent of hair follicle development. The process whose specific outcome is the progression of the epidermis over time, from its formation to the mature structure. The epidermis is the outer epithelial layer of a plant or animal, it may be a single layer that produces an extracellular material (e.g. the cuticle of arthropods) or a complex stratified squamous epithelium, as in the case of many vertebrate species. A developmental process, independent of morphogenetic (shape) change, that is required for a hair follicle to attain its fully functional state. The process whose specific outcome is the progression of a tissue over time, from its formation to the mature structure. The process whose specific outcome is the progression of the hair follicle over time, from its formation to the mature structure. A hair follicle is a tube-like opening in the epidermis where the hair shaft develops and into which the sebaceous glands open. Any process that modulates the frequency, rate or extent of hair follicle development.
