@turkay1-- I don't think vitamin E can reverse male pattern balding. So if you've lost hair, I don't think vitamin E is going to make it come back. But vitamin E may help slow down hair loss.
As far as I know, male pattern hair loss is genetic. There are some medications that help with it, but it's a difficult thing to prevent and reverse.
I personally have reduced my hair loss with vitamin E and biotin supplements. These strengthen hair roots and reduce hair fall. I think my hair loss has reduce to about one third of what it was before the supplements. I have no idea how long it's going to keep working for, but I'm really happy with the results so far.
