For Hair Coloring
For hair coloring: they change the color of the hair (hair dyes and bleaches).
A cosmetic dye is a substance capable of transforming the hair’s natural color temporarily or permanently, removing part of the existing tone, or adding a new one. 70% of women dye their hair at least once in their lives, and many do it regularly.
According to their permanence, hair dyes can be classified into:
Temporary, also known as highlights or color lifts. They are typically used to add color highlights, remove yellowing from gray hair, and cover small amounts of gray hair (<15%). It usually stays on the hair for a week and is easily remove with shampoo.
Semi-permanent or direct coloration. They provide hair color that resists between six and eight washes. They are characterized by low molecular weight, which allows their diffusion to the middle layers of the cuticle without firmly binding to the hair protein. Permanent or oxidation. They act thanks to the intervention of oxidants, which gives rise to the formation of coloring molecules that are fixed in the hair, allowing a long duration of the dye. They are not removed by washing. As a result, its spectrum of tones is broader. They have a greater capacity to cover gray hair (up to 100%) and lighten or darken the hair’s natural color.
Hair Cosmetics
They are preparations intend to contact the hair and the scalp to clean it, enhance its beauty, modify its appearance or protect it. They are use to improve the hair’s appearance and recover it if damaged. And even, on occasion, they can become ‘helpers’ with medical treatments for hair diseases.
For this reason. Dermatologists must know the principles of hair cosmetics, the formulation, use, and side effects of the different products. And thus establish more appropriate diagnoses and treatments in cases of pathological processes of the hair and scalp.
The close collaboration between dermatologists and the cosmetic industry has made it possible to develop more efficient and comfortable products to use when it comes to maintaining, caring for, and recovering hair.
Should I be worries about Allergies?
At a European level, the frequency of severe allergies to hair dyes is shallow; approximately three people for every million consumers. But its effects must be taken into account. We must always be aware of these severe reactions that we cannot minimize.
For this reason, it is essential to carefully read and follow the manufacturer’s instructions and carry out the allergy test each time one of these products is use. And whenever you experience a reaction after using a dye, you should contact a doctor.
However, do not be alarm. As with other cosmetics, the strict safety regulations of the European Union introduce requirements that guarantee total safety for the human health of hair dyes.
What is the allergy test?
The allergy test is a necessary precaution and an indication of the reaction during hair coloring. It is simply a check on whether you are likely to tolerate the chosen color on a small, inconspicuous area of skin. Manufacturers recommend allergy testing before using permanent dyes (also called oxidation dyes). A positive reaction (redness, irritation, prickling, swelling.) is apparent that your body has become sensitized to some ingredient(s) of the dye. As recommended in the manufacturers’ instructions, you should wait 48 hours to give the body’s biological mechanisms time to kick in and assess whether you react to the test before proceeding with hair coloring. In case of a positive reaction, the hair should not be dye. Instead, consult your dermatologist to identify the ingredient you are sensitize to.
A negative allergy test also does not guarantee that you will not have allergic reactions in the future with other colors. Please consult your dermatologist if in doubt.
What would I do in case of a positive reaction to the allergy test?
If you notice any adverse reaction (stinging, burning, itching, swelling…), do not continue. Clean your skin, and don’t dye your hair (not even with any product you’ve already used in the past). Instead, contact the manufacturer (the customer service numbers and technical assistance lines are on the packaging). The company will help you and your dermatologist organize the corresponding patch tests to identify which ingredient causes the reaction.
I have successfully dyed my hair, without any adverse reactions, in the past. Should I do the allergy test?
Yes. Allergy testing should always done. First, perhaps the new dye you will use contains ingredients that the previously used products did not stop. And second, and more importantly, the allergy can develop over time and be caused by another product, such as temporary black henna tattoos. Therefore, it is necessary to carry out the allergy test before each staining for more excellent safety.
