I just dip mines is boilng hot water and carefully towel dry while they are hanging strait down away from you body cause it will burn u! If i want a loose wavy look..i put about 5 or 6 big loose briads in the hot water...dip and unravel the loose briads..makes a very nice wavy texture...the good this about kankelon is..if you wanna curl it one week and wear it strait the next all u have to do is just redip them in the hot water...and it straitens right back out..u can rock a few styles!
