All lace units and weaves from Sisdore have no to minimal tangle/shedding. To prevent tangle/shedding problem, please make sure to wash the unit at least once a week! The main reason for hair tangle/shedding is because the hair is too dry. When you wash the hair(after conditioner and spray the nutrient water) when the hair is almost air dry, use one or two drops of hair care oil on the hair surface especially the ends. This will keep the hair soft and and luster! ① Do not wash the hair with hot water！ ②Do not comb the curly /deep wave hair with tight teeth brush,it will ruin the hair original shape and make it fizzy and feels like tangle!
