Shedding or tangling can be caused when the hair is too dry. Please make sure to wash and deep condition your hair regularly just like with your natural hair. Also make use of heat protectants when styling as well your hair so it doesn't dry out.
When going to bed, make sure to cover your hair in a silk bonnet to prevent tangling. You should also comb your straight hair starting from the tips to the roots using a wide tooth comb.
We do not recommend combing curly hair. It is preferable to work your hands through the curly hair or use a special brush to brush it out.
