Use a tail comb to pick out the hair to cover the exposed fish line, then comb your hair neatly. How to solve the knotting problem? Spray water or wig conditioner & detangler(DIY a detangler ,prepare a spray bottle and put some conditioner in it, then fill it up with water),use a wide tooth comb to comb from the bottom up,cut the knotted area with scissors. If the entire extension is knotted, you can use boiling water to fix it, but the extension will straighten. Braid to ponytail or make a bun to avoid the static if wearing all the day,after smoothing the hair ,use some argan rich oil to maintain the hair. How to restyle the hair? The material is heat resistance fiber ,so you can iron it at 150-180 degrees or 300-350 degrees Fahrenheit. Unlike your own hair ,synthetic fiber only sets after it cools,so use hair clips to keep the curl until it is cools ,then release ! (or use foam hair rollers) If you want to achieve the same curl as your hair, you need to control the cooling time. The longer the time stays, the more curled it becomes.
