Well I might be the worst on here. I kept mines in for four months but I never washed it. Never washed it not one time. My hair grew so much I didn't know what to do with it. It did not dread it did not matt up. But it smelled horrible. OH well I thought that was what you were suppose to do. Next time i got a weave I washed it and my hair dreaded up and matted something horrible. No more weaves. I also did that with braids keep them in four months or more and never wash them. Yeah I hated being in the wind. I will never ever do that again. Never. now 6 weeks are less for braids, but I am not feeling the braids or any thing like that right now.
