Isopropyl alcohol, also called rubbing alcohol, is a selected type of alcoholic solution characterized by high flammability, a powerful odor and a fast evaporation rate. Additionally it is a common ingredient in some hair care products, and even has some hair applications in its pure form. Depending on the situation, its effect on hair could also be considered beneficial or detrimental.
Isopropyl alcohol has a powerful drying effect on hair, as well as on other human tissues, in response to “Don’t Go Searching for Hair Care Products Without Me: Over 4,000 Products Reviewed, Plus the latest Hair Care Information,” by Paula Begoun. In extreme cases, this can leave hair so brittle that it could crack and break, but this is only likely if pure isopropyl alcohol is applied to the hair and left to totally dry. Hair care products that list isopropyl alcohol as an ingredient may have some detectable drying effect, however the concentration of alcohol is usually too low to cause any serious damage.
Isopropyl alcohol is also used to increase the absorption of other substances into hair follicles, in keeping with Begoun. “A Consumer’s Dictionary of Cosmetic Ingredients,” by Ruth Winter, lists isopropyl alcohol as a typical ingredient in hair color rinses due to this property. While isopropyl alcohol might be helpful within the absorption of dye, try to be cautious when using products that claim to moisturize but additionally contain this ingredient. Some such products contain isopropyl alcohol to aid within the absorption of moisturizing ingredients, but since this alcohol has a drying effect, the end result can sometimes be hair that’s dryer than before.

This will intoxicate the head lice, causing them to detach from the hair and come out in the towel, but it will not kill them. Isopropyl alcohol and another alcohol called terpineol are common additives in malathion, an FDA-approved treatment for head lice.
