Is this normal? Wet/shampoo hair spiked up under camera flash.

your hair looks thin when wet, and normal when dry.

looking at your hair wet is always tough as your hair is clumped together. People's density varies greatly from person to person regardless of MPB. Monitor it when dry and see if anything changes. It's all you can do. Unless you want to go to a derm to make sure then get on meds if necessary.
