Is there a safe hair dye for people who are allergic to regular hair dye?

The last few times I dyed my hair, I got a very itchy, red rash all over my scalp and wherever the dye had touched. I assume that I am allergic to it. Is there any such thing as hypoallergenic hair dye or something?

Since time immemorial, countless stories of how women have searched far and wide to improve their looks and more particularly, their hair abound. History tells us how Cleopatra, the Queen of the Nile who capitalized on her beauty to conquer the Western world, utilized every potion, particularly henna, to improve her locks. Similarly, the Romans閳?fascination with hair dyes was unearthed when a hundred or so dye formulas were dug up in archaeological expeditions. Truth be told, the hair is truly a person閳ユ獨 crowning glory. How one chooses to wear his or her hair may make or break one閳ユ獨 chances of being noticed in the social arena. But before one does anything drastic to change one閳ユ獨 hair color, caution must first be taken in determining how safe a hair coloring agent really is. To dye or not to dye? Health.Care attempts to answer that question as it examines hair coloring agents.



The Color of Hair



Hair color is the result of the distribution of melanin, the skin閳ユ獨 chief pigment, in the skin. In general, the more melanin a person has, the darker the hair becomes. Stem cells living at the base of hair follicles are responsible for producing melanocytes, the cells that produce and store melanin in the hair and skin. A person閳ユ獨 hair color changes typically as one ages. It gradually changes from its natural color to gray, then ultimately to an ashen or white hue. Typically, a person閳ユ獨 hair starts to turn gray when he or she reaches the age of 40. Some indivuduals, however, are born with white hair or have white hair even at a very young age. Genetics is said to be the key factor in determining how soon a person閳ユ獨 hair becomes gray, whether naturally or prematurely .



Changes in hair color are caused by the gradual decrease of pigmentation in the skin. This occurs when melanin ceases to be produced in the hair root and when new hairs grow in without pigment. Two genes appear to be responsible for the process of greying, Bcl2 and Mitf. The death of the melanocyte stem cells causes hair to begin going grey.



Classifcation of Hair Coloring Agents



Although the graying of hair is a normal part of human senescence, many often think of its social implications and regard it as unsightly. As such, people who have faded hair color resort to hair dyes to become confident and make their hair aesthetically acceptable once more. Depending on one閳ユ獨 needs, people choose different hair dyes to achieve their desired hair color. There are four categories in which hair coloring products are grouped into. These are permanent, semi-permanent, demi-permanent and temporary dyes.



Permanent Dye



Permanent hair color makes use of a chemical process that involves the breakdown of the natural color pigment in the hair and the diffusion of the new artificial color into it. Permanent dyes generally contain ammonia, oxidative tints, and peroxide. A permanent hair coloring agent begins to work when the oxidizing tint completely penetrates the hair cuticle or the cell layers covering the hair follicle. Once the oxidizing agent has penetrated the cuticle, the peroxide in the dye, in conjunction with an alkalizing agent, usually ammonia, breaks down the melanin in the hair cortex. The hair follicle, in effect, is thus being decolorized or bleached. As the original color of the hair is effectively removed, the pigments of the artificial or desired color diffuse into the hair shaft and proceed to color the hair follicle that has just been bleached. The dye is said to be permanent as it replaces the original pigment present in the hair follicle. Hair colored with permanent dyes is removed or replaced only when new roots begin to form in the hair follicle.



Although it does not contain ammonia and peroxide like most permanent dyes, henna is considered as a permanent dye because it doesn閳ユ獩 wash off with regular shampoos or rinses. Its active component, lawsone, binds to keratin in the hair, making it permanent. Henna may be removed with mineral oil.



Semi-Permanent Dye



Semi-permanent hair coloring agents are formulated to last through several shampoos. Its staying power is dependent on the hair閳ユ獨 ability to absorb moisture. A semi-permanent dye閳ユ獨 pigment molecules are small enough to partially penetrate the hair shaft and stain the cuticle layer. Semi-permanent dyes impart color on the hair while at the same time retain the hair閳ユ獨 original color. Semi-permanent coloring agents are typically used to cover gray hair, where very minimal natural pigment exists.



Demi-Permanent Dye



Demi-permanent hair colors deposit pigments in the hair shaft without lightening it. Its pigments completely penetrate the hair shaft and so last longer than semi-permanent hair color. It will not lift, lighten color or cover gray because it does not contain peroxide which is an absolute must for lifting color. However, it may contain other ingredients that may trigger allergies in some people.



Temporary Dye



Temporary hair colors are a more subtle way to neutralize unwanted tones. The pigment molecules of a temporary coloring agent are large and therefore do not penetrate the cuticle, imparting color only outside the hair shaft. It does not contain peroxide and ammonia, thus it doesn閳ユ獩 strip or lift away hair閳ユ獨 natural color. As such, no breakdown of melanin takes place. Temporary hair dyes can be removed after shampooing hair several times. Acid dyes function in a similar way in that they only coat the surface of the hair. Having a low affinity to hair, they easily are removed after shampooing. Hair cellophanes are an example of a temporary dye



Dyes and Allergic Reactions



The allergic reaction that comes from hair dye is generally one of sensitization to p-phenylenediamine (PPD). The reaction will most likely occur each time one dyes one's hair and will probably get worse each time. Others meanwhile argue that serious skin reactions to hair color can be linked to ingredients such as ammonia, peroxide or diaminobenzene. Allergic reactions to dyes include itching, swelling of the face, and even difficulty breathing.



Ammonia and Peroxide-Based vs. Non-Peroxide and Non-Ammonia Dyes



Permanent dyes are peroxide-based, meaning they bleach the hair first before depositing or imparting new color on the hair. Peroxide, a colorless liquid, achieves two major actions. As discussed above, it breaks down the natural melanin in the hair shaft which instantly "lifts" the color of the hair, making it lighter. It also releases oxygen, which combines with the dye molecules and helps them to develop and deposit color. Ammonia combines with peroxide to optimize the bleaching effect.



On the other hand, a class of hair-coloring agents, the non-peroxide, non-ammonia dyes, imparts color on the hair without first removing or stripping hair of its natural pigmentation. The only downside to non-peroxide, non-ammonia based dyes is that they may not be able to lighten hair that is dark or heavily pigmented (unless of course it is being used to cover graying hair.)



Depending on one閳ユ獨 skin sensitivity to ammonia and peroxide, it is best to check which hair coloring agent suits one best.



The Risks of Using Dyes



Although a lot of people continue to rely on hair dyes to improve their appearance, many are still ambivalent about using it because of the health risks they may pose. Aside from allergic reactions to some of the dye閳ユ獨 active ingredients, however, there are no clear cut links between developing different forms of cancer and the constant use of hair dyes. Hair, by itself, is dead and cannot transmit toxins to the body. The scalp, however, is at risk of absorbing harsh elements, if indeed dyes have cancer-causing chemicals. As such, one must make sure that dyes are completely washed off from the hair to prevent toxin retention in the body.



Although pregnant women are always cautioned against using cosmetic products suspected to be harmful to fetal development, there is no actual evidence available that hair dye is harmful during pregnancy. However, many practitioners recommend not dyeing a pregnant woman閳ユ獨 hair in the first trimester when the fetal organs are forming. Processes like highlighting, which don't contact the scalp, are probably fine because they don't get into the body.



Despite the absence of evidence linking hair dyes to several ailments or diseases, it is best to keep the following precautions in mind when using hair coloring products:



閳?Don't leave the dye on the scalp longer than necessary.



閳?Rinse the scalp thoroughly with water after use.



閳?Avoid contact with eyes.



閳?Wear gloves when applying hair dye.



閳?Carefully follow the directions in the hair dye package.



閳?Never mix different hair dye products, because it can induce potentially harmful reactions.



閳?When using a dye for the first time, patch test it on the ears and leave it there for 2 days before using it. If no itching, burning, redness, or other signs of allergic reaction develop at the test spot during this time, one can be relatively sure that there will be no allergic reaction to the dye when applied on the scalp.



閳?Never dye the eyebrows or eyelashes



Until concrete evidence is gathered with regard to the health risks hair colorants or dyes pose to its users, it may be assumed that most hair dyes available in the market today have been tested and are therefore safe for application. However, when in doubt, the best way to stay away from health hazards caused by dyes is to not use them all. After all, the safest, and by far, still the best hair color is one閳ユ獨 very own.
