On you tube Naptural85 has a tutorial about making your wash & go last 5 days. She takes a spritz bottle full of water & spritzed the area above her head. She lets the mist from the water spritz fall on her hair. Then she puts a plastic cap on her head, covers that with a satin scarf covering the rim of the plastic cap so she won't have breakage, & goes to bed. She does this every night & her wngs last 5 days.
