I have a high quality, professionally made wig on eBay that can be worn as is as a wash and go style or can be flat ironed straight and curled or roller set: http://m.ebay.com/itm/321941831398?_mwBanner=1
Wear it as a protective style with it sewn down on to a braid base for two - three weeks at a time or remove it nightly.
Are you familiar with 'Megatek'? Apply Megatek to your freshly washed scalp while wearing a braid base and repeat every few days for at least an hour or apply it often as if you were 'greasing your scalp' before you sew the wig down. You will see a increase in growth.
I have a thick layer of Megatek on my scalp between my braid base right now. I put it on before my pre-dawn workouts and wash it off in the shower after the workout.
