So I have a mohawk that I want to add dreads to. would you still recommend 5-7 packs? Or could I get away with 1 or 2?

Depends on the mohawk and how you want your finished style to look. That said, we do offer a 30 day money back guarantee on unopened products. You can buy more than you think you need, and then send back anything you don't use. Its a pretty sweet deal.
