Q1: How many bundles do I need for one head? A1: 8-18 inch, 3 bundles is recommended; 20-30 inch, 4 bundles is better. Q2: Why my hair getting tangled or shedding? A2: 1) Your hair can get tangled due to dryness, oil & dirt build-up, and not combing (wide-tooth comb) out the hair daily. Please wash & condition your hair at least once a week, then let the hair air dry. Use hydrating drops or your hair stylist for more help. 2) Usually the hair won’t shed, you can check it before installed. If you cut the weft many times when installed, it will shed easily from the place you cut, you’d better put some glue in the cut edge. Q3: Can the hair be dyed, straightened, curled? A3: As it’s 100% human hair, it can be dyed and usually it’s easier to darken the hair than lighten. Use a flat iron/straighter or tongs, pls don’t exceed 150C, and pls don’t do it too frequently, or the hair will easily get dry and tangled. Q4: How long does the hair last? A4: This is 100% human hair, it can last for a long time depending on how you maintain it. Treat it like your own hair and take good care of it, usually it can last 8 months to one year. Q5: What kind of hair care products should I use? A5: Use good quality shampoo and conditioner, conditioning is very important to keep your hair soft and manageable. You can also use products like gel and hair spray to keep the curl in place, but make sure to wash your hair and not leave it within these products for a long time.
