Oh dear ,just caught sight of DF in it. Really how many people are fooled by these things. Its so playing on people's insecurities. I'm sure they make money by people just not returning them even if they don't work ,a bit like the No No.So cynical.Just because its expensive doesnt mean it works. ... My hubby and sons both have male pattern baldness but they don't care ,just keep their hair groomed. my hair is thinning since menopause but I wouldn't go for any thing like this .Again grooming can do a lot. I'd rather go for a wig if it got really bad.
