Allergic reactions:
Allergic reactions are certainly a significant concern. Hair colorants contain skin sensitizers and can cause allergic reactions, sometimes even after a product has been used several times or many years. These reactions can appear at any time and are subject to personal variables.
For any allergy concerns, we advise not using the product until you review the ingredients with your doctor. Each person, allergy, and reaction are unique, and we cannot generalize that all allergies to "sulfates" are to a certain type, or allergic to all types. If you choose to go forward with your doctor’s approval or your own decision, our prescribed sensitivity test is the best way to see if the product is personally tolerable. This simple test can be done under the supervision of a dermatologist, if you desire. As always, our Customer Care and Color Specialists are here to help.
IMPORTANT! If you have any kind of reaction, immediately discontinue use of the product, and seek medical advice related to your specific allergy. As always, safety first, and we are here to help if needed. Attached, you will find a list of ingredients to review with your doctor or dermatologist.
Allergic reactions: Some coal-tar hair dyes can cause allergic reactions or sensitization that may
result in skin irritation and hair loss. People can develop sensitivities with repeated exposure. In
addition, formulations may change over time. So, it’s possible to have a reaction even if you
have dyed your hair in the past, without a problem. That’s why it’s important to follow the
instructions and do the skin test before every use. Even if you don’t see a reaction to the skin
test, it’s still possible to have a reaction when you dye your hair.
One hair dye ingredient, p-phenylenediamine, or “PPD,” has been implicated more prominently
in leading to allergic reactions. Some people may become allergic to PPD from other exposures,
including occupational exposures. This is called “cross-sensitization.” Here are some examples;
- Some temporary tattoo inks, sometimes marketed as “black henna”
- Certain textile dyes, ballpoint pen inks, some color additives used in foods and drugs,
and other dyes used in semi-permanent and temporary hair dyes
- Rubber and other latex products
- Benzocaine and procaine, local anesthetics used by doctors and dentists
- Para-aminosalicylic acid, a drug used to treat tuberculosis
- Sulfonamides, sulfones, and sulfa drugs
- Para-aminobenzoic acid (PABA)External Link Disclaimer, a naturally occurring
compound used in some sunscreensExternal Link Disclaimer and in some cosmetics.
Temporary tattoo artists who use coal-tar hair dyes to color people’s skin are misusing these
products and ingredients, because coal tar hair dyes are not intended to be used for staining the
skin. While FDA regulates cosmetics products on the market, professional practice is generally
subject to state and local authorities, not FDA
If you have a reaction to a hair dye or tattoo, ask your healthcare provider about treatment. If
you know what ingredient caused the problem, you may be able to find a product that doesn’t
contain that ingredient. If you color your hair yourself, check the list of ingredients on the label
for any you wish to avoid. If you have your hair colored at a salon, your stylist may be able to tell
you the ingredients, or you may wish to check with the manufacturer.
Questions about hair dyes and cancer: In the 1980s, some coal-tar hair dyes were found to
cause cancer in animals. FDA published a regulation requiring a special warning statement for
all hair dye products containing these two ingredients:
- 4-methoxy-m-phenylenediamine 2,4-diaminoanisole
- 2, 4-methoxy-m-phenylenediamine sulfate 2,4-diaminoanisole sulfate
The cosmetic industry has since reformulated coal-tar hair dye products, and we are no longer
seeing these two ingredients in hair dyes.
FDA continues to monitor research on hair dye safety. We do not have reliable evidence showing
a link between cancer and coal-tar hair dyes on the market today. We are collecting adverse
event data which helps us assess the safety of this class of ingredients. If you experience an
adverse event or bad reaction, please report that to the FDA (see below).
So nowadays hair dyes can be considered safe while they are use under normal conditions,
being the main problem of the hair colorants the risk of sensitization since hair colorants can
cause severe allergic reactions.
