My hair is thick and wavy so I look dirty if I don't shampoo it everyday, since my scalp is oily.

You might want to look into shampoo bars. Sometimes when the scalp is over shampooed, the stripping caused by shampoo causes the scalp to over-compensate with oil production.

see here for the sciencey stuff:

Shampoo bars can mediate the over-production b/c they are not (usually) detergent-based and so do not over-clean.

Thanks for the recommendation. This is actually the first time I have heard of shampoo bars. Will definitely check it out.

You're welcome. Please post your results.

I tried no poo and using a shampoo bar and it made my scalp itch. Im sure its great for some but not for me.

Will do! Thanks!
