== Hair matrix cell activator ==
* Hair matrix cell activator is a substance that acts at the matrix cells in the hair follicle preventing their degradation.
'''What causes hair loss?'''
* Stem cells are interspersed within the basal layer of the outer root sheath and in an area called the bulge.
* Stem cells migrate to hair matrix where they start to divide and differentiate.* Growth and differentiation of the matrix cells are , under the influence of substances produced by cells of the dermal papilla.* Perifollicular matrix cells undergo slow degradation which prevents follicle stimulation.* Hair follicle activation is required for hair growth and thus inhibition of follicle activation eventually leads to hair loss. '''How does hair cell matrix activator treat hair loss?'''* Hair cell matrix activator slows down and inhibits degradation of the perifollicular matrix.* This leads to an increase in hair follicle matrix cells that differentiate from progenitor stem cells.* Matrix activator allows activation of hair matrix cells and therefore follicle stimulation leading to hair growth.
