I am not against it. Studies show that they seem to be good carriers for derma-rolling. More so, eh, it seems like a lot of work for you but you are motivated. I don't know that stacking ten oils is better than using one; and I understand the notion of "couldn't hurt so throw it in there" but often the converse is true and things might work at cross-purposes.
The real reason for my sigh, apart from lack of sleep is that Janey wants something better for you guys. Baldness is such a grind to fight that I wish XY's had some more tools in their arsenals. Here's a really good article about Rosemary Oil. Half of what I think I know comes from Perfecthairheath.com. The site is actually called Perfect Hair Forever which is not very creative plus there's show called that, some cartoon so if you don't use the actual address in google, you get pages and pages about what appears to be a dreadful adult cartoon. Let's us know how it works out for you--oh yeah--I forgot. With so many oils, you will struggle to know which might be causing improvements but that's true of any stack. I would love to see some guys doing single shot, RU, CB, A-tradiol and so forth but most seem to use two to three similar treatments and there's not much photographic evidence:
A study claims that rosemary oil is as effective as minoxidil for hair loss. The catch: they only tested 2% minoxidil. So, does rosemary really regrow hair?
