Papain Hair Growth Patent

I was inspired by the recent papain thread to do some research and stumbled across this:

Some quotes:

This invention relates generally to a kit that includes two separate products that are sequentially administered to a human scalp and the kits' method of use to promote hair growth in humans. One of the products of the kit comprises of monoethanolamine salts of thioglycolic, salicyclic, lactic, and glycolic acids in combination with an enzyme. The other product is an oxidizing agent.

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 accumulations 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.

then why am i loading up in antioxidants if these guys us oxidation to regrow hair?
