i dont wanna spend a whole bunch of money for dye,can i just use food coloring?my hair is brownish red and is pretty dark in the winter,what color would go good with my hair if i was streaking my bangs with something bright?

I just got a trim on my bangs and they are too short. All i need is for them to grow about a half an inch to an inch for them to be the right length so i can push them to th side. My school starts in 3 or 4 weeks so i reallyyy need them to grow for school pictures!! Is there a shampoo or creme or vitamin or food i can eat to make them grow faster?

My hair used to be really curly and pretty, and healthy when I was younger, and I started straightening it about 3 years ago, and ever since then, my hair hasn’t been cooperating when i want it to be wavy.
like some of it is wavy, but my bangs are just straight and poofy kind of.
I want pretty wavy hair that looks healthy, even though its not.
im not cutting it, so you might as well just leave that out if youre considering that.
what are some good products to have silky wavy hair?
