No lo he usado pero tengo malas referencias del producto. Me han dicho que no ayuda mucho en el crecimiento de tu cabello.

It was hard to believe something like this might work, but it really does. I had some problems to find it in my neighborhood ( not every pharmacy has one) , but recently had my luck with rite aid, it's around $21 plus tax, I saw it couple times at groupon for cheaper, but they didn't have color I need( dark brown). It's a little expensive product, but works wonders for thin hair, makes it visually much fuller. Just make sure you are washing your hair in the end of the day and don't go to bed with a fiber in your head, it's almost impossible to get rid of the fiber from pillow cases.
