Hi there! My hair is a shiny, very dark deep shade of brown (almost black) with a wavy to curly texture. I have a very thick head of hair, and the individual strands themselves are very thick as well. I am always complimented on my hair. People often tell me I have "mermaid hair," due to its' thick waves and long length. It is 5.25 inches in circumference when in a ponytail. It is washed, at most, once every 10 days and has never been processed, dyed, blown out, permed, relaxed, or subjected to any other salon treatment. I wash my hair with Suave shampoo and conditioner. I allow my hair to dry naturally; I do not blow dry it. I have never been a smoker. I have a 1 year old baby that is breast fed, so I have not drank alcohol for more than 2 years. I have taken prenatal multivitamins, calcium, and DHA supplements regularly for years and follow a healthy diet, eating mostly organic foods. 13 inches will be cut and is available for sale. Thank you!
