While natural hair scrubs are a great way to enhance hair health, they should be used in moderation. Over-exfoliating the scalp can lead to irritation or even damage, so it’s important to use a scrub no more than once or twice a week. For best results, it's essential to follow up with a hydrating conditioner to lock in moisture and prevent the scalp from becoming too dry. If you have a sensitive scalp or are prone to scalp conditions, it's always a good idea to patch-test new ingredients before applying them to your entire scalp.
