As per alcoholic concerns -- I read throught the patents a while back...I'm sciency, I grew up with origami and dinosaurs.
The alcohol is used as an organic solvent during sonication. That is when the stuff is being shaken by sound waves, yielding the appropriately small sized phospholipid liposomes (essentially tiny fat balls) that carry active ingredients past the skin barrier to the fat/lipid layer underneath where they can work their microcirculatory boosting magic. Before anyone jumps on that - it's not frkn magic - it's science! magic is not real.
but!! after sonication the organic solvent -- most likely ethanol -- is evaporated off because it's not needed. liposomes don't need a vehicle to pass through the skin barrier - that's the whole point. Beyond the soothing feeling of knowing that your microcirculation is getting jacked, you should feel not much at all.
it will not contain alcohol! your head will not feel irritated. You will feel great as the wind blows through your flowing locks.
please dont pile on me - there's a lot fo aggresive hairloss sufferers on here!
