Two phase Nair

Nair is a thioglycolate that dissolves sulfide bridges at hair If you use it on sensitive skin though it causes a rash

I think that a version of nair where a first fluid is an emulsion with metal ions like Zn that just attach to hair rather than skin then a second fluid that is catalyzed to be active thioglycolate is possible

if it works then Gilette could have a new product
