Can you explain what you mean? How do they relate?
The short version the proponents say that sebum blocks the follicle from being able to breathe or emerge. The carbonic acid supposedly removes the sebum plugs in a way that normal shampoo cant.
Im told that cosmetologists are presently being taught that the trick of these products is actually the stimulation the bald spot receives when “rubbing the product in for 15 minutes” or whatever that product directs.
I suppose a person could test it themselves. Its free to stimulate your own scalp by rubbing for 15 minutes a day. If it doesnt seem to work then try the plug removal shampoo. If that doesnt work then Id guess that neither are true.
You shouldnt believe anything I say, I shave my head bald these days. (Work related)
Ha ha ha...
