As my hair gets longer, and I keep bleaching it, I am worried about it getting damaged and dry. I purchased some olive oil sheen spray. My hair was somewhat dry even after a good conditioning. I sprayed a liberal amount on last night, and slept with a bandana on overnight. My hair is nice, soft & manageable. It's not overly greasy. More like after a couple of days of not washing where your hair has it's nice natural oils (and is easier to comb and style). I was skeptical that it would leave my hair greasy, especially since this product is aimed at a black/African American market (and found amongst the other black styling supplies). It was about $4 for the aerosol can.

I'm looking forward to trying some other products by this company.
