This is not an ad. This is a real, grown-ass man. I have been dealing with moderate to severe seborrheic dermatitis (dandruff) that often causes flaking and inflammation on my face and head. I have used the toner only 1 time but I wash and condition my hair with the complimentary shampoo and conditioner every day. (I was earlier instructed by a dermatologist to wash every day to reduce build up.) I have no problems right now, not even itching! I have used steroid shampoos, and various other methods and nothing has worked this well for this long. I cannot recommend this enough. Whether it's the toner, or the shampoo and conditioner, buy this product if you're suffering. Truly thankful.
