For the best results, try this quick quality check. Brush the hair; if strands fall off the weft(the seam at the top strip of hair), the quality is poor. This can happen with inexpensive hair. But if that is all you can afford, try sealing the top of the weft with a hair glue or using clear nail polish to secure the track. Either one will minimize the shedding. But to eliminate all of that invest in good quality hair it is re-usable and will lat longer.
