I recommend salon shampoo.

My current hair salon sells this. I stocked up on it during a promotion last year and have been using it ever since, and it's really good. My daughter is practically threatening me, saying she won't use any other shampoo.

It seems like my hair falls out less, is shiny, and gets nourished.

However, the price is a bit steep unless there is a promotion. Still, I highly recommend it.
