Ammonia is a dangerous, carcinogenic chemical
The professional salon industry is generally under the impression that ammonia is safe. However, this caustic toxin which is most commonly used to in commercial cleaning products and to manufacturer explosives, is actually
considered to cause cancer by the World Health Organization and the United States Environmental Protection Agency. In addition to being a carcinogen, their is strong evidence that ammonia also causes the following health problems.
- Long term exposure to ammonia fumes can cause obesity, depression, and social anxiety disorder.
- Daily exposure to ammonia will cause high blood pressure, pulmonary edema, and bronchitis.
- Continued contact with ammonia hydroxide will dry the skin and damage skin cells and eventually cause serious skin complications.
- Exposure to ammonia fumes will damage eyes, liver, kidneys, and lungs.
- Even brief exposure to ammonia fumes can be an asthma trigger and irritate or amplify allergies.
Ammonia should not be used in hair colour
Ammonia has the following destructive effects on hair.
- The corrosive characteristics of ammonia destroys the tyrosine in human
hair. Tyrosine is the protein that regulates the production of melanin, hair’s
natural pigments. Therefore, using ammonia in hair color destroys hair’s natural
ability to “hold” color.
- Ammonia causes a destructive inflammatory effect on follicles rending them
dormant for an indeterminate amount of time and causing hair to thin.
- The corrosive characteristics of ammonia, while an important property in
opening the cuticle, irreparably damages the cuticle which sacrifices the hair’s
structural integrity. Although conditioning the hair will help to temporarily
close down the cuticle, it does not restore the hairs structure or repair the
- Because ammonia extracts water from the cells, it depletes the hair of
moisture. Also, the corrosive characteristics of ammonia will destroy and
incapacitate the sebaceous glands which produces sebum, the hair’s natural
moisturizer. Although moisturizing hair treatment will temporarily restore some
of the moisture, it will not replenish the moisture deep in the hair’s cells
that ammonia has extracted.
