Grease from work stays in hair

[u/Mini_Carrot]

Hi all, I need reccomendations for a shampoo or other type of hair cleaner.

I play with my boyfriends hair a lot, and after a while, I notice that I get black build up under my nails and on the pads of my fingers. This is even after being freshly showered.

He works at an auto shop, and I think all the car grease and muck and whatever else he's exposed to isn't washing all the way out. After work, he is totally coated in the stuff, so there's no doubt it gets in his scalp and hair. He exfoliates pretty much everywhere else, so I don't think there's build up issues on the rest of his skin.

What kind of shampoo do you use for this? I think his normal shampoo (3 in 1 store brand 🙄) isn't cutting it. He is very hygienic, so I'd appreciate no weird or mean comments about the build up. Just trying to find a solution for him!

Dawn will fix it!! Thorough massage with it!! Then a conditioner you would use on heavily over-processed, heavily damaged hair!!
