The inversion method is a relatively new hair growth technique that’s said to help hair grow by 1-2 inches per month. It’s a very interesting technique that continues to gain a lot of popularity in the beauty arena. Sadly, there is very limited research done on the technique. This basically means there is no way of telling if it really works or not. That hasn’t stopped some people from trying it out, though, and from the online testimonials, we get a really good impression that maybe it does work.
