As you said, the increase in oiliness is compounded upon daily use of shampoo

As a short term effect, not a long term change in sebum production, the sebum glands are most likely primarily genetically and hormonally controlled.

I also said > Some people experience less oiliness over time, but this is likely due to changes in distribution, absorption, and perception, rather than a true shift in sebum gland function.

Using it frequently will eventually strip all of the oils out (if you’ve got long hair - People with shorter hair shouldn’t have an issue).

I know what you’re saying, but it could be interpreted as that the glands on your scalp just stop producing altogether, which is not true and if it happens likely presents a serious medical issue.

I briefly touched on the distribution of oil in your hair - if you brush long hair thoroughly and frequently you distribute the oil from the glands to the tips, which gives the perception of less oilier hair and is in fact, very healthy. Oil in short hairs obviously distributes faster and more easily from the glands to the tips, so a more frequent use of shampoo doesn’t impact healthy hair as much.

Like I said, proper scalp hygiene can accommodate a wide range of hair washing habits. But if you forego that you’ll get nasty issues.
