Okay, I had a few confusing moments reading your post
. apparently you are having issues with the products you're using in addition to brushing. Personally, I am a DIY person. It is easier to eliminate 'chemical' product issues. Try some basic things as co-washing with VO5, or Suave. I am not sure of your relationship to Texturizing(sorry if I am confused, it is afterall Saturday evening
). Start off neutral...Co-wash with the above mentioned conditioners. Condition with Eggs..Mayo...Honey...EVOO. Go 'natural' for a while, for me it's the best thing. Even Avocado or Bananas. These will not hurt your hair, but you will most likely benefit. ACV, and Aloe Vera is always beneficial for restoring the pH your hair needs.
Good Luck. Hope this helps
