Applying products containing alcohol before haircutting can cause dryness and damage to the hair, making it more difficult to manage during the haircut. Applying products with alcohol before shampooing can also strip the hair of its natural oils and make it more prone to breakage. During hair coloring, the chemicals may react with the alcohol and cause damage to the hair. After high-frequency treatments, the hair and scalp may be more sensitive and applying products with alcohol may cause irritation or discomfort. Therefore, the best time for products with alcohol to be applied is after high-frequency treatments as the hair and scalp are less likely to be affected and the product can be more easily rinsed off.
