From what I've read is that it supposedly works both internally and topically. I'm thinking of trying some of the hair oil. There are some reasonably priced brands out there. You can also get it in powder form but I don't know how well it dissolves.
I'm experimenting with my own concoction. The carrier oils used are virgin olive, avocado, jojoba, grapeseed and castor. The essential oils are cedarwood, thyme, eucalyptus, rosemary, lemon and lavender.
Look all I know is this the only thing that has ever given me any action. I'm gonna stick with it for at least a year and see what happens. Maybe it only grows baby hairs or maybe over time they will start growing healthy and at a normal rate, only time will tell.
Still looking up for me. The hairs I initially shed are starting to come back and I don't have to strain so much too see the freshly sprouting hairs on the temples. I'm still a little astonished that anything is growing there and I look at them obsessively. I'm optimistic about it and can't wait...
