The initial growth phase during which the hair follicle actively produces hair.
A transition stage between the anagen and telogen phases of hair growth
The main body of the hair shaft.
The scale structure covering the exterior of the hair.
A translucent piece of tissue surrounding the hair's shaft near the root. It contains the richest source of DNA associated with hair.
A molecule with a high molecule mass.
Fibers derived from either natrual or synthetic polymers; the fibers are typically made by forcing the polymeric material through the holes of a spinneret.
A cellular column running through the center of the hair.
DNA present in small structures (mitochondria) outside the nucleus of a cell. Mitochondria supply energy to the cell. This form of DNA is inherited maternally (from the mother).
Two or more atoms held together by chemical bonds.
The basic unit of structure from which a polymer is constructed.
Fibers derived entirely from animal or plant sources.
DNA present within the nucleus of a cell. This form of DNA is inherited from both parents.
A substance composed of a large number of atoms. These atoms are usually arranged in repeating units or monomers.
The final growth phase in which hair natrually falls out of the skin.
