Millions of women and men use hair dye to enhance, update or change up their look. Most people tolerate hair dye without a problem, but it can cause a reaction in some users. These reactions, known as contact dermatitis, are due to various chemicals in different types of hair dye. Symptoms include scalp redness, flaking, itchiness, and burning or stinging. Contact dermatitis caused by hair dye can be due to direct chemical irritation of the scalp or an allergic reaction. Since irritant and allergic contact dermatitis frequently cause the same symptoms, medical testing is often needed to determine whether you have an allergy to hair dye.
Chemicals in Hair dye
Para-phenylenediamine (PPD) is a key ingredient found in the majority of permanent and semipermanent hair dyes. It's also the most common cause of an allergic reaction to hair coloring. There are PPD-free hair dyes, which frequently contain an alternative chemical called para-toluenediamine sulfate (PTDS). However, a significant number of people who are allergic to PPD also react to PTDS, according to a study published in the July-August 2011 issue of "Dermatitis." Other chemicals in hair dyes -- such as ammonia, peroxide, and various fragrances and pigments -- can also trigger scalp inflammation and itchiness due to either direct irritation or an allergic reaction.
If you use dye to color your hair, you might be among the 5 percent of people that develop an allergy to the product. ParaPhenyleneDiamine, or PPD, is found in most commercially produced hair dyes, as is peroxide. When the two react, the PPD becomes partially oxidized and colored; in this state, it can lead to an allergic reaction.
Symptoms --Symptoms of an allergic reactions to hair dye can develop within 1 to 48 hours of application. The following are the symptoms of hair dye allergy.
This is the most common symptom of an allergic reaction to hair dye, and the risk of developing the condition rises with usage. Dermatitis involves inflammation of the skin. Sufferers will experience redness, itchy or swollen skin around the eyelids, ears, hair line, beard or neck. A person who develops a sensitivity to PPD will not experience symptoms until at least 10 days after her first usage. Subsequent exposures can produce a reaction in 6 to 72 hours.
Symptoms of this condition, also known as hives, can include red skin, eyelid swelling, red patches on the body, wheezing, sneezing, difficulty swallowing and vomiting. Symptoms can be seen about an hour after exposure to hair dye. Urticaria occurs when PPD triggers a series of chemical reactions that leads to the leaking of blood plasma into the skin
Anaphylactic Shock
This is the most serious potential symptom of a reaction. It is rare but can result in swelling in the face, shortness of breath, a drop in blood pressure and death, in that order. Someone suffering these symptoms should seek immediate medical assistance.
Patch Test
To determine if you are allergic to the PPD in hair dye, follow the instructions provided with the product. In general, you will be directed to apply a small sample of solution (dye and developer mixed together) behind your ear or to your inner elbow. Wait 48 to 72 hours to see if symptoms develop. If not, the product is considered safe to use.
Hair dye use and Pregnancy
When you use hair dye or other hair products, a small amount can penetrate your skin. Generally, however, the chemicals aren't thought to pose harm to a developing baby.
While a 2005 study suggested an association between the use of hair dye during pregnancy and the development of the childhood cancer neuroblastoma, other studies haven't reached the same conclusion. Most researchers say it's unlikely that maternal use of hair products before or during pregnancy would increase the risk of childhood tumors.
If you choose to dye your hair during pregnancy, consider these general safety precautions from the Food and Drug Administration:
·         Follow package directions carefully.
·         Wear gloves when applying hair dye.
·         Leave the dye on your hair no longer than directed.
·         Rinse your scalp thoroughly after using hair dye.
If you're concerned about the use of hair dye during pregnancy, consult your health care provider or consider postponing any chemical hair treatments.
