Frederic Fekkai Salon Technician Shampoo and Conditioner For Dry, Damaged, Color-Treated Hair is the very best conditioner I have used so far. It is expensive but it's worth every penny.
I have tried so many shampoos and conditioners from drugstore to high end and this has been the best for my hair type. I have highlighted blonde hair, it's thick, dry, damaged... and the top is SO dry sometimes it's almost crispy! Plus I blow dry and use a flat iron or curling iron everyday.
Since I've been using this Frederic Fekkai Technician Shampoo and Conditioner it's looking a lot better. It's softer, more moisturized, shiny and overall looks so much healthier. These products have really changed the life of my hair.
