To avoid the ‘irons and hot curlers’ routine every morning, try this technique: braid your washed and blow-dried hair in the night and sleep with them braided. When you undo the braids next morning, your hair will be wavy and have volume. This is by far one of the best do-it-yourself techniques to add more fullness and body to fine hair together with natural waves! For the waves to last longer, put Velcro curlers in them while they cool down after blow drying.
