This is a great shampoo for people with oily hair. My daughter developed oily hair in the past few months. I tried several different shampoos, but they all left her hair looking greasy after just a short while. Her hair would look oily most of the day even though it was washed well at least 1 time each day. She was also getting a but of buildup on her scalp and behind her ears. On top of that she tends to have dandruff, which is something else we want to prevent.
I bought this product. It really works for her. She needed to wash her hair every day, but at least this shampoo keeps it looking clean for most of the time between washes. It has helped with the buildup, and it has also helped reduce her dandruff.
