Firstly, keep your locks clean. Dirty locks harbor dirty smells, and it’s difficult to cover that up. After you’ve cleaned your hair, feel free to use essential oils, fragrance oils, and scented hair spritzes on your locks to make them smell nice. Be careful to avoid overapplying strong scents, which can be difficult to remove from your hair. This generally isn’t a problem, but if you accidentally put too much of an unfavorable scent in your hair, it may be difficult to get out for a few days.
