Head & Shoulders Moisture Care Co Wash [SEP] I received a sample of Head & Shoulders Moisture Care co wash for free from BzzAgent. I used the co-wash today. It left my hair feeling smooth while washing The scent is pleasant while washing hair. My hair type is wavy, frizzy, fine to medium strands, to lower back. The sample I received was very small so I could not wash all of my hair with it. My problem with it is all of the harsh chemicals it contains.
