does the shampoo you're using have dimethicone or proteins in it? both of those will pull my hair out and make me dry and frizzy. Protein if too much is in there and the other if it's in my shampoo.
Usually frizzy when wet is buildup of some sort. Hard water, protein or cone.
Some can shampoo daily with no problem some can't.
Is your hair better after you shampoo it? Oh and do you use a DT weekly?
Low porosity, medium texture.

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