Help!

What do you use or found that works best for hair loss and breakage? I was diagnosed with pcos in March, my hair was at the bottom of the list to figure out how to manage. I swear it’s a rats nest literally seconds after I brush it. I braid it when going to sleep I don’t wear high buns or pony’s or anything really. I RARELY put heat on it. I typically wash my hair every 3-4 days, throughout summer and constant sweating I’ve falling into the habit of washing it everyday, I’m currently trying to retrain it and starting with every other day. I’m so tired of losing so much hair and it constantly being tangled. Please leave me some affordable hair care products. (Shampoo, conditioner, leave in , oil, literally anything 🙏🏼) I will take all the tips and tricks I can get!
