Besides the campfire smell, there’s nothing better than the scent of freshly washed hair with fragrant shampoo.
Grab a dry shampoo. Many dry shampoos are odorless, so for this demanding task, have one with a favorite fragrance.
Rub a sparse amount of baking soda into your scalp and comb it throughout your hair. Within seconds, the campfire smell will disappear.
Lemon juice is another alternative people have used for ages to help diminish unwanted smells. Plan ahead if this will be your method, though, as the citrus mixture needs to sit overnight.
