Sorry I meant a Deep treatment. Somethign to put some moisture into your hair.
I'm sure you do know your hair. YOu might have gotten ahold of a product that is bad for it or maybe you just need more moisture because of the winter weather.I have to use a heavier conditioner now and Dt more often.
I got ahold of a product with that dimethicone in it and didn't know it and that caused me some upset for a bit. I'm not totally opposed to anything used on hair just for the sake of saying something is always wrong for hair but that stuff just is bad for MY Hair. It's ok say in a styler but in shampoo or conditioner that's a no no for me.

I sure hope you figure out what's going on with your hair soon. I can feel for you.
Low porosity, medium texture.

If it smells good put it in your hair, if it tastes good spit it out!
