I use it, and currently use Strength Cure. It was recommended to me by my stylist when I said my hair felt dry and frizzy.
It really helped that issue. She also said to use the deep conditioner in place of regular conditioner until it felt better. It has worked.
I was using the more expensive Nanoworks, but find the less expensive Strength Cure works better for me now. For awhile, the Nanoworks was really good for me.
My stylist said as our hair becomes more gray, the texture changes and it can feel frizzy like that. Yuck!
I got a sample of Pantene and tried it over the weekend. My hair feels FRIED from it.
I had great, strong, hair. The more gray it gets, the worse it feels. So, if you think you've got hair you can use a 99 cent shampoo on now, it may not be like that later.
