    Flaking scalp resolved completely!

    I purchased this duo after an unsuccessful trial with a common dandruff shampoo. My hair felt like a bristle brush. Necessaire left it shiny, soft and free of flaking after first shampoo. I’m so impressed with your products!!!

    THE best fragrance free shampoo

    Seriously, I have tried probably 20 other brands and they didn’t come close. I pair it with the fragrance free conditioner.
