oooh I have a similar question too.. I'm looking to purchase some no-wash shampoo. The kind you can just massage into your scalp but don't have to wash off. I guess the correct term is leave-in shampoo as stated above? lol. Yea.. the reason is because after a day of not washing, my scalp gets really oily and gross, but the strands are still stiff and dry, so I don't want to wash my hair allover just to clean the scalp part.
