Nothing For The Hundreds in Money Spent
I have been taking this expensive product for one year now and have noticed zero hair growth and even a bit of thinning. I still maintain my hairline from when I was in my 20s (I’m 51 at present), but the top of the head has thinned. I have taken this product as directed (religiously) for one year and I can say with great certainty I have wasted hundreds of dollars! Snake oil.
I don't Know How It Works on me
Well, my hairs have certainly thickened after using this for 1.5 months but I am also losing them at a faster rate now. My hair density is waning. It could be that Propidren is not amusing me so I am just going to switch.
