Will your hair you shed while using Rogaine grow back?

[Dinko9]

Dr. Baxa i've been using rogaine/regaine now for 2 weeks and my hair has really started to thin out on top after using it. Before i started using rogaine my hair was already thin on top, but now it really started to thin out. I'm considering it stop using the product and maybe move on to something else. I was wondering what other hair loss products/shampoos etc you would recommend i use..I'm considering using nisim, is it any good? I'm only 21 and this is a realy blow to my self esteem, its kinda depressing looking in the mirror every day any seeing a young guy with a receding hairline!
