I need hair help!

So, last summer I was swimming a lot and did not realize how badly damaged my hair was by the pool until the damage was done, I lost half or more of my hair, it was brittle, dry, tangled, and just all over screwed. I wanted to buy a wig, cried for a bit. It's growing back, slowly. But, I need help, still. I can't do much with it, I cut it short, but it's still damaged. What can a salon do for me and what would be the cost? For a cut, and to make it healthier again.

Having ugly hair brings me down and makes me feel bad. Pretty hair makes me feel confident and pretty, just help plz thanks:)
