My friend Natalie came in this last week for a haircut. She has extremely thick hair. I shaped the perimeter and gave her some layers.
Her ponytail is about 5x's thicker than the typical ponytail. Her hair is in perfect condition. She has virgin hair!!! Pretty amazing!!! She said it would take about two days to color her hair due to it's thickness lol, and after blowdrying and flat ironing it I believe her!
