Can we please stop spreading this myth? Scalps do not adjust sebum production based on how much is washed off. There's no way for dead hair cells to report oiliness to their follicles - they don't have nerves, they don't send signals.
Sebum production is controlled by hormones. Different people produce different amounts. If you find that washing your hair every few days will suffice for your skin/hair type, that's great. But that advice doesn't work for everyone. If someone with skin that naturally produces high amounts of sebum follows your advice, they may end up with Seborrheic Dermatitis, which can cause dandruff, hair damage, and hair loss.
How do you explain going from excessive oiliness in less than 30 hours to the same level of oiliness taking 7 days? It was a long transition but you're telling me I'm a freak and everyone else with the same outcome are simply outliers? I know there's a genetic aspect, but I had a very real change over time.
There’s nothing wrong with it if it works for you.
Personally, I produce a lot of sebum, and I’ve had to consult my dermatologist about it. I’m not a medical expert and I won’t claim to be - I just don’t want people who are in my boat to follow medical advice that could make their problems worse. One size does not fit all.
Someone just tried to educate you. Which part of what you were just told are you taking issue with?
