i really recommend protein in your regimen. i hair is very thick, coarse, and kinky, so even when i relax with a super it doesn't really go full straight. Protein has helped me strengthen my hair against flimsiness that comes from damage or bad weather. For the past year or so i've been wearing weaves as a protective style but you can opt for many other ways like buns, bantu knots, braids, etc. Include protein it really helps make the hair less resistant to breakage, you can start weekly protein treatments along with weekly moisture treatments to try getting your hair back in a good state. moisturize and seal daily if you have your hair out, just spritz your hair with a moisturizing conditioner mix with water, and then seal with an oil afterwards.
I know exactly how you feel i live in MD and the weather can be a real downer at times, but when you establish a regimen that works for you will be able to overcome it!
