I've been using this product for about a year now, and can honestly say it's the only 'beauty' product I couldn't live without. I use it daily without fail and am so impressed by it. My hair has been thinning for a few years, and it got quite bad about 18 months or so ago. I was starting to get extremely conscious of the amount of head which was showing and how thin my hair was at the front and along the parting and crown in particular. This product gives me a confidence in my hair which I haven't had for years. I use quite a bit of it - one tub does just a couple of weeks (no way near 3 months!) - but I lift my hair up in sections and sprinkle it on, and give my head quite a good covering. This means that if the wind blows my hair up or I want to tie my hair back (which I haven't been able to do comfortably for years), I don't have to worry about it. I struggled a bit with getting the very front of my hair to look right to start with, but now use one of the rootz colours brushed on lightly first before giving a really light sprinkle of the fibres and it looks pretty natural, even under harsh lights. I love the fact that it's a natural product and the fact that it's vegan/not tested on animals is really important for me. I would recommend this to anyone who feels they want to add a bit of volume to their hair, but more so to anyone who is conscious of overall thinning/patches of head etc. showing - it will transform the way you feel about your hair!
