To use it as a shampoo, add one to two tablespoons of baking soda in a jar that contains one to two cups of warm water. Make sure to mix it well before pouring it on your scalp. Massage it well on your scalp to evenly distribute baking soda then rinse. To use it as a conditioner, mix in half a cup of baking soda into a bowl of conditioner.​ If you cannot ditch shampoo altogether, an option would be using baking soda as a rinse, dilute half a cup baking soda into a cup of warm water. Use this mixture after washing with shampoo.​
