Review title is GOOD BUT NOT ALWAYS GREAT [SEP] I loved this shampoo and conditioner for the first several weeks that I purchased it again.<br />However, after continued use it seemed to have a build up on my hair weighing it down<br />and causing frizz on the thinner front of my hair. My hairdresser confirmed that overuse<br />will build up the oil from the Argan Oil Shampoo and Conditioner. I have decided to use<br />it occasionally instead of every time I wash my hair. I will use Matrix Biolage advance Full<br />density shampoo and conditioner in between using the Argon shampoo and conditioner.
