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. "
it seems that it is needed to
- firsty break cystine into cysteine.
- This allows to remove connective fatty tissue cells away from the follicle;
(these 2 steps are achieved with the first procede serum apllication, lasting 1 hour)
- Finally, through a process of oxidation, cystine is formed again, thus returning keratin to its original state.(this is achieved by the second procede serum application, lasting half an hour).
