Review: 5/5 stars - I have a widows peak that was thinning, and it was an insecurity of mine when I put my hair up. Started applying for 1-2 months, and already see results!! It is working a bit too well and making my peach fuzzies on my forehead a bit thicker…. But I’ll take that over thinning hair
Review: Runs out fast/roller does not dispense the product - $26 and the roller does not work. First one I got worked but product ran out quick and I only used on front hair line area. Second one ran out quick or stopped working no way to tell . Got a new one today brand new and barely any comes out if any. Would love this item in a spray or dropper so I know how much product I’m actually putting on my scalp this feels like I’m being cheated or scammed
