True, I started as I began thinning and luckily caught it early enough. It hasn't solved the pre-existing thinning completely, but it's prevented any further loss and resurrected enough follicles that were on the verge of death that if you were to look at me on the street, you wouldn't say I'm thinning/balding.

The problem with doing anything after "full" balding has progressed is that the follicles have just completely died off, which is way more difficult to solve than preserving or stimulating existing growth
