Right now I'm using the expensive Loreal Professional series but it makes my hair dull and oily.
Any advice?
Is pricey really better?

i have always been a fan of fructise garnier, its about 6 dollars depending on where you go.

Vive shampoo cleans my hair like no other but the conditioner is awful.

Head and shoulders, been using it all my life and now my whole family uses it, great shampoo even if you don't have dandruff.

suave is a very good brand to get and its not to cheap and works wonders. pantene is amazing to but it can get a little on the pricy side. hope i helped

No pricy is not always better.
If you want a shampoo that makes your hair less oily and is "anti residue" get the neutrogena anti residue shampoo. This product is literally squeaky clean. But i definetly reccomend a conditioner because the shampoo doesn't leave your hair soft. Try a pantene conditioner of treatment, there products are amazing.

They are quite cheap something like $5.00 canadian. Just go to your local drug store or whereever you get your shampoo and check it out.

I would definatly reccommend suave, aussie, or pantene brands. try them out and see what works best.
