Make sure you’re not going to bed with wet hair.
I’ve had this issue. I love the osmo volume shampoo & conditioner (Amazon or TikTok shop is cheapest) I get two good hair days and the third I can spray with dry shampoo. Before this I had to wash every other day 🤦🏼♀️ I agree with washing twice with shampoo too and only condition the very ends
Green People shampoo and conditioner. I wash once a week and rinse with water once weekly in-between washes.
I use glycolic acid or salicylic acid on my scalp leave for 10 minutes a rinse and wash hair as normal. They both love oil to the absorb and break down oil as well as them being chemical exfoliants the get rid of any build up and dead skin which increases oil production. Doing this I've definitely noticed that my hair doesn't get as oily as quick. Don't use these anymore then once a week as it can hurt ur scalp with over use as scalp is more sensitive. However dont use if u have any super dry patches or cuts or open wounds on head. Also when ur done in shower or bath and hair is dry use dry shampoo on it before bed and just leave it don't brush out till morning, ur oil produces most oil at night so putting dry shampoo on it before it gets oily stops it from getting as oily in first place and use a little dry shampoo before bed every night to increase longevity of grease free hair. Make sure u wash ur hair twice in the shower first wash gets rid of a bit of grime n dirt second wash actually cleans ur scalp x
