A: Shedding: A few strands initial shedding of new hair is normal. We always suggest customer seal weft before installing and brushing it with wide-tooth comb. Excessive shedding will cause by weft cutting or dryness. Please always seal the ends if you cut weft for installation and keep it moisturized. B: Tangle: Usually, our hair will not tangle because it is cuticle intact human hair. However, dryness, oil & dirt build-up, salt water or not combing out daily will lead to tangle and shedding. Please follow hair care instruction and use good shampoo & conditioner to wash hair twice a week.
