The Hack: Applying mouthwash to the scalp to get rid of dandruff.
Safety First: Experts have agreed that the antifungal and antiseptic properties in mouthwash might make it effective in helping to soothe mild cases of seborrhoeic dermatitis, better known as dandruff. "However, they are super drying and caution must be taken to reduce irritation to the skin and scalp," says Henry. An already irritated scalp that may be sunburned or cut from scratching to ease itching, can be further aggravated by the ingredients in mouthwash. Overall, the benefits seem to outweigh the hazards, but if you are going to try this, Henry recommends diluting the mouthwash with water.
