I'm sorry to have to say, but the idea of "hair training" is a myth.

The oil glands (which are known as sebaceous glands, and produce an oil called "sebum") are controlled by genetics, hormones, and stress. Sebaceous glands don't have any sort of "sensor" to tell them when to produce more/less oil, so washing or not washing won't make a difference.

Thank you. I have extra oily hair so if I skip washing it even a single day it starts to look like I'm using pomade, and whenever I tell people this they always insist I should just wash it once a week and my head will "adjust."

I am the exact same, friend. My hair becomes a big oil slick after only a day without washing and it's really obvious. Which is part of why this particular myth bothers me so much.

First, as teens, we had uninformed randos without oily skin telling us to heal our acne problems by putting nonsense like toothpaste and silly putty on our faces. Now, those same uninformed, non-oily randos tell us that our greasy hair can be solved by not washing it.

But my dermatologist was right about the acne care they recommended, I'm inclined to trust them about my scalp care too.

Yep, I had really bad acne when I was younger and the only thing that worked was isotretinoin, which is rough. My lips cracked and bled while I was taking that but when I was finished the acne was gone.

They made me pledge not to get pregnant while taking it despite the fact that I don't have a uterus, lol.

I took that stuff too (aka accutane). Severest depression I've ever experienced but I'm thankful to only get the occasional acne as an adult now.

I knew /r/nopoo was a lie!
