The 2pcs set: you will receive 2x8 inches (20cm) with 4 clips each piece FAQ Q1: Can they be straightened, curled? A:Treat the hair as it is your own hair. Use a flat iron/straightener, but as with your own hair, never use hot tools too often. Q2: Can I dye or bleach the hair? A:yes. The hair can be colored. As a general rule it is easier to darken the hair than to lighter the hair. We highly recommend having your hairdresser dye the extensions, coloring them yourself always poses a high risk of not coming out the shade you want. If you can not get to a salon, use a good quality hair dye and test a small sample first please. Q3: Can I wash the hair? A:you can wash them as you would your own. Shampoo and conditioner. Because the hair is not attached to your scalp, it is not getting the oils it should be. We also recommend using a hair treatment on them every few weeks. Q4: Can I blow-dry the hair? A:The extensions can be blow-dryed on low setting, but it is not recommended to do it too often. It is best to let your hair extensions dry naturally after washing them. Q5: Why are my hair getting tangled? A:Your hair can tangle due to dryness, oil, dirt build-up and not combing (wide tooth comb) out your hair daily. Make sure to wash and condition your hair at least once a week, comb the hair daily and use hydrating drops. Q6: How long does it last? A:This hair can last for a very long time depending on how you maintain it. Treat it like your own hair and take very good care of it for it last longer. The seller reminder: 1.
