I've been using Revivogen for just over one month and whilst I don't want to get over confident it appears to be working very well. I have short hairs coming up in all my thin areas and they are not fine hairs. I have not experienced any shedding as described by so many people in discussion forums. My hair loss has decreased dramatically and if this continues I will be continuing with this product. So far it has done everything the makers of this product have stated. It is early days yet and I will report back again to let you know my progress.
