My hair has never been dyed, curled, or straightened. Rarely blow dried, last time was a maybe a year ago. Washed every 3 days or so with Hask brand of shampoo and conditioner, occasionally Renpure Advanced shampoo and conditioner. In summer, small waves in the hair begin to appear and It’ll get highlighted streaks when exposed to sun frequently. The texture of hair is very soft and shiny. Some days the hair can have a lot of natural volume. Individual hair thickness is I believe average. Very minimal damage. I stay away from processed foods, my diet is healthy overall. I do not smoke.
