no one asked for this but i can't help but share.
i got this a couple years ago: https://www.amazon.com/gp/product/B000JI9JYQ/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
it's amazing and and i actually don't mind brushing my hair now. i think i have a sensitive scalp in general but i also have a history of daily headache so it doesn't take much to trigger severe pain.
check out youtube videos of it in use and see if you think it's a good match for sensory issues related to brushing hair, it's perfect for me.
PS if you drop it, the "bristles" will break, so you should actually use the protective cover it comes with. ask me how i know :/
