The 1st time, was just a trial run. I found out some areas would still need at least a light leave-in. The second time I used it, the hold was still going strong for nearly 4 days. I would like to wear a wash n go longer... but I have a very oily scalp, and roots that will start matting past 4 days. I usually wash every 3-4 days to avoid the scalp buildup and tangles/matting issues.
