The Alberto VO5 treatment conditioner is simply worthless and useless. The conditioner tends to leave your hair feeling heavy and greasy.
I have tried different products by VO5 and I havent really been happy with any of them. Their shampoo may clean, but their conditioner makes you want to wash your hair again.
I am not sure exactly what ingredient that makes your hair feel lousy, but I do know it is in the VO5 conditioners.
I have had the same effect after using different VO5 conditioners whether I blow dry my hair afterwards or just let it dry naturally.
I would stay away from this brand of hair conditioner and pay a little bit more for a better brand.
