For me, I have used all kinds of shampoos and even went to the salon and the recommended a nexxus brand claiming it would work. Before then I was using pantene for women of color and it was working fine for me Knowing the other shampoos I was using messed up my hair. The Lady at the salon told me don't us pantene. After I used the whole bottle of nexxus it messed my hair up soooo bad I went back to pantene. It went to work and I saw the huge difference it made. I'm Hispanic and black so I have a mix of both types of hair which is really hard to deal with let alone finding the right shampoo to work with it. Pantene is doing good for me too. I was thinking the person that made this little article could have been allergic to some of the products and maybe should figure out what it is that shes allergic to.
