well I can definitely say that it doesn`t make you Loose any existing hair or fluff! so in that respect it`s nice to know it`s at least Safe to use.
the very fine hairs around my hairline seem to have grown a little, but I guess they kinda were doing that anyway. I still really need at least another month to test this though, as 2 months should equal about 1 inch hair growth, I do have the advantage that I also dye my hair and that makes measurement much easier as it grows out.
I`ll update again soon. xx
