Change in hair type

Laura

This might be a little random, but my hair has totally changed and I don't know what to do with it! Or what's left of it but that's another matter. I've always had straight, fine hair. It's still fine but now is very frizzy. I have to be careful with products bc they easily weigh my hair down. Do y'all have any products you like? Do I use a straightener? Help!
