GREAT PRODUCT
I started to use this product  about 2 yrs ago. It has made a great difference in helping to stop my hair loss. My hair grows fast and this accelerated it. I was surprised at the end of three months that it was slowly beginning to get thicker.  I have very fine hair and any loss is noticeable. I cannot say it help to darken my hair, must say it has stopped falling out, except for normal shedding and looks healthy again. I am a avid user of this product and tell my friends about it. . It does take about 2 to 3 months to see a difference.
