Treat the hair extensions with extra care will extend the life span of it. Have hair extensions professionally applied by a trained stylist experienced in hair extensions The best temperature for using a flat or curling iron is from 260 degrees Fahrenheit to 350 degrees Fahrenheit. Once beyond 350 degrees Fahrenheit, the hair will get dry, split easily, even worse the hair will get fire. The more you use heat on it, the shorter the life span of your hair. We recommend you always try them on a lock of hair first to ensure they will not damage your extensions. Do not flat iron or apply excessive heat to the bond itself, as it was installed with heat. You can but it is not recommended that you perm, tint, bleach or cellophane the extensions since they have already been bleached or colored during the production process. If you perm, tint, bleach or cellophane the hair, you will do it at your own risk. Make sure your extensions are untangled before you shampoo them.

Also stay away from ones that contain sulfur and alcohol as it breaks down the hair extensions faster than desired It is not recommended that swimming, diving, Sauna or Sunbathing with hair extensions. Salt water, chlorine water, heat, and sunlight do great harm to hair. However do comb out tangles, braid hair into one braid at back of neck before any of these activities and always follow with appropriate shampooing and conditioning as needed after any of these activities Never fall sleep on wet hair. Make sure the hair and bonds are dry before bedtime to avoid matting. When you sleep, we highly recommend that you braid, wrap or ponytail your hair together to prevent tangling. This will save time that would be spent untangling the hair the next morning. Use a satin pillow to also prevent tangling. How to Wear Divide your hair into two sections Make the Preparation rows.
