25 inches of 4 inch thick, virgin, wavy brown hair. Washed 1-2 times weekly, no blow dryer, only air dried. No products, hair dyes, curling irons or flat irons have been used on this beautiful hair. I take daily vitamins and am a non-smoker. Hair will be cut by a family member, who is a licensed hairstylist. I have been growing my hair since I last sold it, 4+ years ago.
