@LouisSarkozy - Here is the diy misture I'm using: I use a 60ml plastic applicator bottle w/ squirt tip screw top. Into this I add 5ml of the following. (all these are the liquid alcohol versions of the extracts) dong quai, sophora, polygonum multiflorum, rosemary leaf extract, red clover herb, korean red ginseng, The Ordinary (I will drop this one when used up). I also add 1ml of the following essential oils: rosemary essential oil, peppermint essential oil. Essential oils can be irritating in higher %. Not sure if this mixture is doing anything, but, they have citations which have merit for hair growth. Especially polygonum mulitlorum for wnt / b-catenin. I don't think they can hurt, so, I will continue to use this mixture 2x daily. I believe the active topicals for me currently are needling / minoxidil / clobetasol / tretinoin.
