When cutting, we recommend making pieces with a 4" minimum width to maintain the integrity of the weft. Lifespan: Average 6-12 months. KOVI hair can last many months if cared for properly. To increase longevity we recommend trimming the hair every 3-4 months to keep the ends healthy. Refresh the color/tone as needed to maintain vibrancy. Coloring KOVI hair: Many stylists tone and color KOVI hair. Semi or Demi-permanent color is recommended. Permanent dye, bleach, lighteners, and perms are highly discouraged as they can damage the cuticle. KOVI recommends always doing a test strand to make sure you are happy with your results prior to applying color to all of your hair. Hair Care Tips: hair care page.
