My hair was perfectly fine until I used a different shampoo once and ever since my hairs been dry and I can't get it back to how it was in the first photo. I shampoo 3-4 times a week depending on how active I am as I sweat a lot. What is causing this and what can I do?

In the 1st photo my ends are super dry and flick up, its been like that ever since I used a different shampoo than my usual one and it dried out my hair like crazy, I used argan oil a bunch and it helped somewhat but not fully. In the other photos is how my hair usually was, what can I do to hydrate the ends and get my hair back to normal? I can provide further info on my hair routine if needed.
