I use the smoothing Shea Butter shampoo and the ever straight brazilian keratin therapy. it works great it makes my hair feel extremely soft and I have thick hair with 2 textures straight and curly. the shampoo isn't drying and it doesn't feel crispy crunchy after I wash it out. The hydrating keratin mask makes my blow dry and flat iron less time consuming and it leaves my hair feeling nourished, shiny and healthy. It's a great buy and I suggest trying it out.
