Ugeat hair extensions can be used for a long time and will never cause damage with good care. However, it's worth noting that they should be refitted after they've started to grow out to avoid pulling on your natural hair and damaging it. Q: Can i use the purple shampoo wash the hair? Hi girl, we do not recommend that you use the purple shampoo to bleach the color. Although our hair is 100% human hair, it will damage the hair, if you insist to do so, please pick up a strand to test and apply to the full head. Q: How many packs do I need to buy? Usually 150-200g is better for a full head look. If you just want to highlight with your hair or see the color, 25-50g is suggested. Q: How long will my Ugeat hair last? The lifespan hair extensions is determind by how well they are cared.What products are used on them,and how often they are worn.Usually the lifespan of hair extensions is 3 months.Depending on the general care they received.
