Hi this is my first post!

I'm a combo 3a/3b and have been on the no-poo dry cut method for about 11 years. Suddenly, like in the last month, my hair is super dry, tangled, and frizzy.
My hair's pretty long now - mid back dry - and it's super windy where I live so that probably makes it worse, but I'm also 53 and having hormone stuff going on.
The deep conditioners aren't doing it, I'm using really high quality products, and my diet is great. I don't know what else to do!
Have any of you had this sudden change in texture, and what do you do about it?
