My hair now does this without the flatiron! - Waves in 15 minutes! Section hair into big sections then braid each in a loose braid. Run a flatiron over each braid, let them cool down, spray hairspray and undo the braids.
If you swish with hydrogen peroxide everyday you will have the same results plus excellent gum tissue! Recommend swishing with peroxide for minutes morning and night. It kills bacteria that causes decay, gingivitis, periodontal disease. Worth a shot!
