Which ingredient is commonly found in scalp exfoliators?

Scalp exfoliators often contain sea salt because it is effective in gently sloughing away dead skin cells, product buildup, and excess oil from the scalp. The granular texture of sea salt allows it to provide a physical exfoliating action, making it suitable for those looking to achieve a healthier scalp environment. This can promote better hair growth and improve the effectiveness of other hair care products applied afterward.

While jojoba oil and coconut oil are excellent for moisturizing the scalp and hair, they do not serve the same exfoliating purpose as sea salt does. Shea butter, on the other hand, is primarily known for its hydrating properties rather than exfoliation. Thus, among the given options, sea salt stands out as the ingredient most commonly associated with scalp exfoliation due to its unique ability to remove dead skin effectively.
