Chemical depilatories are one of an array of temporary hair removal methods on the market. They typically come in cream or liquid form, though shaving powders are also available. They dissolve the hair by reacting with its protein structure, according to KidsHealth.org. Then you wipe them away. Depilatories come in various strengths depending on the areas of the body for which they are designed, so it pays to read the package carefully before buying one.
Benefits
Depilatories are widely available at drug stores and supermarkets, and you do not need a prescription. They work quickly and tend to be effective on the legs, underarms and bikini area, according to KidsHealth.org. Some also work on the face. The results last several days to two weeks.
Disadvantages
Depilatories can lead to skin reactions, such as inflammation or a rash, according to KidsHealth.org. You should test them on a small patch of skin before applying them to broader areas, and avoid using them on skin that is already damaged or sore. Additionally, they are not for use on the eyebrows, because they can cause severe damage to the eyes, according to the Children, Youth and Women's Health Service of South Australia. Some people also dislike the smell of depilatories.
Special Use
Chemical depilatories can be a good option for men with razor bumps, according to the American Osteopathic College of Dermatology. The group estimates that 60 percent of African-American men and others with curly hair suffer from the condition, in which hairs in the beard area grow back into the skin and cause inflammation. Depilatories consisting of barium sulfide or calcium thioglycolate can be helpful, but men often find that their skin cannot tolerate the products because the area with razor bumps is already irritated. The American Osteopathic College of Dermatology recommends using a depilatory less time than the package indicates and using it only once per 48 to 72 hours.
Considerations
The March of Dimes recommends against using chemical depilatories during pregnancy because the skin may absorb such products. Shaving, waxing and tweezing are better options. If you do decide to use a depilatory, the group suggests keeping the room well-ventilated and not leaving the product on the skin longer than necessary. Also, you should keep in mind that the skin may become more sensitive when you are pregnant, making you more likely to have an adverse reaction.
Warning
Depilatories can be poisonous if swallowed. Among the harmful chemicals they may contain are calcium hydroxide, barium sulfide and thioglycollates, according to Medline Plus, a service of the U.S. National Library of Medicine and the National Institutes of Health. "Extensive damage" to the mouth, throat and stomach can occur. Medline recommends calling your local emergency number, such as 911, or the National Poison Control Center at 1-800-222-1222 if a depilatory is swallowed.
