This listing is for 15-16" of my hair. I don't smoke and I don't do drugs. I eat healthy. My hair is shiny, strong, and full. I don't dye or blow dry my hair. It sits in a pony tail every day and is only combed/brushed once a day to try and prevent breakage.
It's got just a little bit of a curl/wave to it, but will blow dry flat with no real issue. It does have some natural highlights from being out in the sun off and on, but has never been chemically treated.
