Double processing your leave out; color & relaxer will possible change the texture of your hair and cause breakage.
Before these gray hair hit me, my leave out was quite long, about 10" and I could have the nicest, smoothest waves to blend w/ my curly weave. I didn't even do a full strength relaxer, just texlaxed w/ a super mild one.
Once I started dyeing my grays in my leave out, it broke off to about 3-4 inches around the edges and about 6" in my U. I can't wear my hair in a bun or ponytail anymore w/o having to use a scarf to hold my edges down because my leave-out doesn't go into a ponytail all the way over the tracks anymore.
Even when I texturize, my hair is nowhere near as soft and smooth as it used to be.
But, I can't rock these gray hair!
