Well these things don’t happen overnight so I think OP is doing the right thing to keep her DD from being teased for her hair.
On shampooing, might not work depending on how bad the sensory issues are but have you tried something like this:https://www.amazon.com/Massager-Updated-Shampoo-Massage-Silicon/dp/B07CWQ5CZ4
My kid has mild sensory issues but will use it to help spread shampoo over her scalp. I think it helps get hair cleaner; I have started using one myself! Also my DD loves “fancy “ things and is very motivated by fancy shampoo, soap etc. I let her use my nice stuff pretty regularly!
Also can emphasize showers can be very fast. Just shampoo and soap and out in 3 minutes. Leave in conditioner has come a long way since I was little!
