Have you tried getting a lace frontal and maybe researching a good aliexpress (cheapest option) on YouTube? You don't have to any leave out and if you have a good stylist, it will look like its growing from your scalp. I bought one along with some bundles back in June and love it, it gave my hair a rest from all the damage that was done from flat ironing it. I like looking at Doll Face Barbie reviews and bought from a store that he suggested. It was inexpensive and the hair was great.
And for kinky hair, yeah it won't last, no matter how much they rave about the quality. Just get something inexpensive, again aliexpress, and maybe have someone create a unit for you or make clip ins, that way you can take better care of it because it's not on your head!!!
Maybe your hair is the kind of hair that grows when you leave it alone. Mines do. I just keep it simple and it grows like weeds.
