Great shampoo with lots of buildup

I bought this shampoo in my endless search for the shampoo for oily hair. I have fine hair and a lot of hair, with a dry scalp that gets fat quickly. With this shampoo, I have a bit of a love/hate relationship. He does his job well, after washing my hair really feels squeaky clean so he does what he promises. However, what is often a disadvantage of these types of shampoos is that they can strip/dry out your scalp quite a bit and so does it to me. It gives me flakes and unfortunately my hair gets fat again just as quickly as with other shampoos. If you suffer a lot of buildup, this is really great, but I wouldn't use it every time myself. Once in a while, I still use it with a lot of buildup. Furthermore, great shampoo, foams enormously well, smells nice.
