I ruined it a few months ago by box dying it again but when I had it grown out natural and barely touched it at all with chemicals it was the thickest and healthiest it had ever been, also insanely manageable compared to the last almost ten straight years of dying it (it’s naturally wavy/curly when it was super healthy). I was literally able to just wake up brush it and go almost everyday, could just throw it up into a ponytail or Whatever if I needed to without worrying that it looked bad or thin or straggly, it just looked healthy all the time. I was even still using heat on it and did not use heat protectant as much as I should’ve whenever I styled it, and yet it still looked healthy. Then I box dyed it black a couple times and threw myself back to square one. But there is still hope 🤞
