Hi Stephanie! If you have dark hair I'd be a little concerned that this product might make you grey. It's quite powdery and can be difficult to control the "sprinkling" of the application... unless you're very careful to only apply to the under-sections of your hair.

Maybe go for a spray product. I don't find them quite as oil-absorbing but they're also not as bad with turning your hair a different colour.

Everyone raves about Klorane and Batiste - both are pretty inexpensive.

You might also consider Bumble + Bumble's tinted hair powder. It comes in all different shades to match your hair colour. http://www.bumbleandbumble.com/product/spp.tmpl?CATEGORY_ID=CAT72&PRODUCT_ID=179
Again, it's not quite as oil-absorbing in my experience - and I didn't like not being able to touch my hair (if you touch your roots, you'll get some of the tinted powder on you), but the grey won't be a problem.

Hope this helps!
