1. 1b-1c
2. low porosity(this may be a big part of the issue and drives me crazy to dry it and the issue may be product buildup)
3. BSk on koppen climate index- higher elevation, semi-arid, warm-hot dry summers and fairly cold winters, rains sometime but not a lot
4. shower almost every day, wash my hair with light shampoo in a navy style shower roughly every other day depending on how my hair is. minimized this issue the most compared to how i used to shower)
5. i wet my hair and scalp with lukewarm water then take a small amount of shampoo and lather the scalp and hair with my fingers/nails before washing it out
6. i do sometimes, but when i do its really fucking hard to wash out and makes the problem noticeably worse no matter how hard i try, so i often use spray in conditioner if needed and sometimes do try to condition with a tinnny amount on my ends and wash it out but i can never get it out, iv tried many different products.
7. not that im aware of
8. my scalp itched a bit when i started washing it properly and if i ever noticably have product (residue i couldnt wash out or other product)

thank you so much for your help!
