Is there a good protein treatment to help get my protein moisture balance back?

I've been using a deep conditioner that's too heavy for my hair and weighs down my fine curls and makes my hair flat. I THINK it's because my protein moisture balance is off so I was wondering if there are any protein treatments to help with this? Preferably diy or under $20

Which products are you using?
For me a whole raw egg works. Cracked in a bowl, beaten and left on hair for 15 minutes. Just disinfect whatever it touches because of salmonella.
