At what age does greasy hair stop?

Greasy hair often lessens after the hormonal fluctuations of puberty, typically stabilizing in the late teens (around 18), but oiliness generally decreases naturally with age, leading to drier hair in your 40s and beyond as sebaceous glands produce less oil. However, individual experiences vary, with genetics, lifestyle, and sometimes even dry scalp (causing overproduction) influencing oiliness at any age, so it doesn't stop abruptly but shifts over time.

Yes, sleeping with your hair down can contribute to it getting greasier faster because of increased contact with your pillow (transferring oils, sweat, skincare residue) and more opportunity for scalp oils (sebum) to coat strands, though factors like scalp oil production, bedding hygiene, and products used also play a big role. Keeping hair up loosely or wearing a silk bonnet can help, as can regular pillowcase washing. 

How do I train my hair to be less oily?

To train your hair to be less greasy, gradually increase time between washes to reset scalp oil production, use gentle sulfate-free products, only condition mid-shaft to ends, avoid touching your hair often, and use dry shampoo or texturizing products on off-days to manage oil without stripping natural moisture. This "hair training" process teaches your scalp to produce less sebum by not constantly stripping it away with harsh shampoos.
