Virgin dark blond straight and thick hair

My hair has never been treated or coloured and I don’t use a hot air dryer or other heat equipment. I very rarely use shampoo, so this hair is about as virgin as it comes. Because I have my hair tied in a bun most of the time it has not been exposed to so much wear and tear. I take B-vitamins every day, so my hair is strong and I almost never have split ends. I have some waves, as seen in the image, but it is quite straight.

The hair has been cut (see photo). Ends were not trimmed prior, so take into account that some might have to be taken off the end. All the money will go to fund clean water projects though charity: water. The buyer can be mentioned in the donation if this is desired.
