Dry hair/scalp?!

Ma
I hope someone else is having this issue! My hair is sooo dry, and my dandruff is terrible! I have no idea what to use! No Heads & Shoulders! It's a nightmare on my hair! I'm mixed black and white, so I already have a hard time balancing it out, but now it's making me miserable. All I can do is put my hair up every day and I'm sick of it!
