A little shedding is normal, although we recommend sealing the weft and cut areas. Tangles only occur when hair is extremely dry, not maintained and not brushed and moisturized often. We use machine weft to minimize shedding. You may see a few strands here and there during detangling or styling, but nothing alarming or excessive. The most effective way to prevent shedding is to seal the wefts, as mentioned earlier.
