Serums & Leave-In Treatments

Nioxin's serums are made to improve hair thickness and balance to a dry scalp. These treatments, including our leave-on serums for itchy scalp, help to prevent and relieve symptoms of seborrheic dermatitis and dandruff.

Both men and women can use these treatments with Nioxin's shampoo and conditioner for fuller, thicker hair.
