What types of products typically contain alcohol and are used in barbering?

Hair tonics and aftershave are products commonly used in barbering that typically contain alcohol. Alcohol serves multiple purposes in these products, such as acting as an antimicrobial agent, helping to cleanse and refresh the skin, and providing a lasting scent. Aftershave, for instance, often contains alcohol to help reduce irritation after shaving, while hair tonics can help invigorate the scalp and enhance hair texture.

Hair gels and conditioners, shampoos, and styling pomades or waxes do not usually contain significant amounts of alcohol. Gel and conditioners focus more on providing hold and moisture, respectively, while shampoos are designed primarily for cleansing the hair and scalp. Pomades and waxes are generally formulated to provide hold and shine but do not typically include alcohol due to its potential drying effects on the hair.
