What will happen if you put mouthwash in your hair?

Using mouthwash on your hair is generally not recommended and can have several adverse effects:

1. Drying and Damage: Mouthwash often contains a high concentration of alcohol, which can be harsh on your hair. Alcohol can strip away natural oils, leading to dryness, breakage, and reduced elasticity.

2. Scalp Irritation: Some mouthwashes contain irritating ingredients such as menthol, alcohol, or strong antimicrobial agents. Applying these to the scalp can cause itching, redness, and irritation.

3. Loss of Color: The ingredients in mouthwash, particularly those with strong antimicrobial properties, may interfere with hair color, especially if you have color-treated hair. It can alter the color or even cause fading.

4. Build-up: Mouthwash can leave a residue on the scalp and hair, leading to build-up over time. This build-up can make hair feel heavy, greasy, and unattractive.

5. Scalp pH: The pH level of mouthwash is typically lower than the optimal pH range for healthy hair and scalp. This imbalance can disrupt the scalp's natural balance and contribute to scalp issues.

6. Insufficient Cleansing: Mouthwash is designed for oral hygiene, not for cleansing hair. It is ineffective in removing dirt, oil, and product build-up that accumulate in the hair.

If you have specific concerns about your hair, it's best to consult with a dermatologist or hair care professional who can provide customized advice and treatment options.
