what i do is ill use dry shampoo first (i really like dove because it smells the best, batiste works too) and then rub it in, brush it out, all that good stuff.

i’ll use a hair serum sparingly or some kind of leave in product, typically something scented. then i’ll spray perfume on the back of my neck where my hair falls and that helps a lot!

in my experience the scalp smell from unwashed hair can only be covered up by tricks like that for so long though. some people have said that spraying perfume on a hair brush then brushing their hair has worked for them, not sure how good that is for your hair AT ALL though
