The genes important for this interaction are slowly being elucidated.Genes important for hair follicle development also play a role in hair follicle cycling.The hair follicle bulge possesses stem cells important for the continual regeneration of the follicle during cycling.Hair pigmentation depends on melanocyte stem cells and differentiated cells in the follicle. Many genes important for melanocyte behavior and hair pigmentation have been defined.
