Shampoos for dandruff are specially formulated to combat flaking, itchiness, and scalp irritation caused by dryness or fungal overgrowth. These shampoos often contain active ingredients like zinc pyrithione, salicylic acid, ketoconazole, or tea tree oil to help reduce dandruff and maintain a healthy scalp. With regular use, they cleanse the hair while soothing and hydrating the scalp for long-lasting relief.
