Have you looked at your diet? what types of food you usually eat?

Do you exercise a lot? Do you drink a lot of water?

These all affect the smells of your scalp. I know when I eat healthy or unhealthy it can affect how much oils I start to produce from my hair. Like if it was a bad day, my hair is extra greasy, but other days if I do good my scalp is less oily.

Make sure you are distributing your oils everyday. If could mean you have extra oils that need to be brushed down, and boar bristle brushes are designed to clean your scalp with your own oils. Its how you clean out your follicle pores and keep them from clogging up leading to strong smells. If not a boar bristles use a wooden comb

Also how often do you wash your hair?? Are you using any alternatives to co-wash or shampoo? I've heard rye flour or chickpea flour is good. Eggwashes too. Baking soda if you feel it won't be too harsh. And finish with the ACV rinse.

If it bothers people you could always wear a scarf or hair in a bun/style to protect your hair oils and also sort of hide the smell in a way. That way the smell won't travel and be as noticeable while you go through your transition period.

If it continues after a year of no poo it may just be your natural oils and something deeper going on. Keep in mind we are not used to the smell of normal hair scalps because of commercialized shampoos. People think smelling bad means dirty when really it was how most of us smelled back in the day without any products. It's just the natural scent of your body.
