My daughter has a virgin natural auburn hair colour. It's a thick, healthy, slight natural wave, soft and smooth texture never been permed, dyed/bleached or coloured and no split-ends. She washes her hair every other day with shampoo and conditioner, and no other chemical treatment. She doesn't smoke, but she socially drinks sometimes. Total hair portion she wishes to sell is 16 inches in length, the thickness of her hair is about 1 1/2 thick.
