Do I have to use these products together? Can I use them independently?

For best results, both products should be used together. However, you can use them independently based on your needs. The Scalp Remedy Shampoo & Conditioner duo is a daily care duo to nourish and balance the scalp. The Exfoliating Scalp Scrub is used weekly to remove build-up on the scalp. These products provide both preventative and restorative benefits.
