from procede patent:
"0016] The enzyme utilized in the preferred embodiment is papain. It is believed that the effect of eliminating the hair-loss inducing connective fatty tissue is achieved by the monoethanolamine salts through the elimination of disulfuric bonds present in the keratin amino-acid cystine. Keratin is the essential component of hair, consequently, of the hair follicle root. Cystine is broken down by the monoethanolamine salts into cysteine, which is the reduced state of keratin. After the damaging cells are removed, through a process of oxidation, the disulfuric bonds are reestablished, returning the hair keratin to its original state. The detergent characteristics of monoethanolamine help carry the removed cells safely away from the follicle which in turn stimulates growth of the follicle. The papain enzyme imparts elasticity over the keratin and skin tissues to ease the elimination of pathogenic cells. "
[0017] Having re-activated the previously dormant hair follicles, and provided said follicles are located in areas where blood circulation is sufficient to deliver required nutrients, hair growth is immediately stimulated and anagenic hair can be seen to develop within a matter of hours after treatment."
