I need help with my hair pleaaase!!!?

I have the same exact hair, same length. Get it trimmed every few months so it can grow faster and more healthy. I use Paul Mitchell's Silky Serum, and it works pretty well. I put my hair in a bun overnight for some nice curls in the morning, and in the morning put hairspray on it. I tried the herbal essence dangerously straight and it didnt work for me. My fav hat protectant is chi heat protectant. Hope this helps!
