Moreover, this essential oil can help maintain your hair color if you’ve recently dyed it. Lemon, beets, honey, and coffee are some of nature’s aids that can help your hair color transform naturally. Henna is the go-to choice for at-home hair care if you want a permanent hair color.
What to do if you have a reaction
The list of possible irritants can then be checked against the ingredients of hair dyes to find the best one for their use. Some people can tolerate semi-permanent hair dyes or lead-based hair dyes, though these options may not be right for everyone. A dermatologist can help determine any chemicals that may be right for every individual they test. Using permanent hair dye products involves an oxidative process, raising concerns about long-term chemical exposure. Studies explored health impacts and the link between hair dye ingredients and cancer risk. The chemical in hair dye that is most likely to cause an allergy is called para-phenylenediamine (PPD).
How to Recover from Hair Dye Allergy and Hair Loss
Contact dermatitis is not an uncommon symptom of this allergic reaction. This may even develop into hives and in some very rare cases, anaphylaxis. This 100% pure botanical coloring product contains no artificial fragrance; most importantly, it’s paraphenylenediamine-free. Coming in 8 color variations, it offers a safe option to cover gray hair for those with sensitive scalps who need more than just a boring black shade.
Paraphenylenediamine and allergy
Undoubtedly, henna is the most widespread go-to coloring solution for both men and women globally. Due to it being nature’s aid for hair coloring, henna is praised as one of the most effective hair colorants even on the most sensitive scalps. Hair dyes can cause a variety of reactions, ranging from mild localized irritations to more serious allergic reactions.
Allergy to hair dye
Hair dyes contain a ton of harmful chemicals that can cause your skin to react adversely. To deliver this type of long-lasting color, often such products use p-phenylenediamine (PPD) and other alkaline chemicals to open the hair cuticles and deliver dye pigments deep into the cortex. Women and men that are looking for safe hair dyes for covering gray hair use oVertone’s coloring conditioner to preserve the natural oils in their hair and nourish their hair shafts.
Fortunately, she was fine—she even documented her hospital visit on Twitter (and posted a pretty gruesome picture), urging her half a million followers to learn about the warning signs of a reaction to dye. While reactions like Perrette's are rare (about one in 250,000 people are allergic), they can be really serious. Some over-the-counter steroid creams may work well enough to manage symptoms if they are less severe. However, more severe allergic reactions may require a prescription steroid cream or possibly oral steroid therapy. These studies have identified hair dyes and their ingredients as having moderate to low acute toxicity, such as causing allergic contact dermatitis. However, the evidence regarding the carcinogenicity of hair dye components in humans remains inconclusive, necessitating further research.
Eczema (also called atopic eczema or atopic dermatitis) is a common chronic dry skin condition affecting around 1 in 10... The eyes also may itch, and the eyelids may swell as the reaction develops. Symptoms typically appear within 48 hours, but strong irritants may cause immediate skin reactions.
As she explains, research estimates that 1 to 2 percent of users experience an allergic reaction and less than 1 percent a severe allergic reaction. Switching your hair color is an easy way to upgrade your look when a new season comes around and you’re itching to change things up. However, for someone with an allergy to para-phenylenediamine (PPD), it can be a challenge.
If you have severe allergies, you may need systemic corticosteroids in pill form or given as an injection. The allergens become antigens and interact with a part of the immune system's defense (T-lymphocytes). The interaction triggers the release of cells (cytokines), which causes an inflammatory response in just that part of the body (localized).
Reversing these trends poses a significant challenge, as some individuals continue to use hair dyes even after being advised of their allergy risks. In a London retrospective survey, positive reactions to PPD on patch testing doubled over six years, reaching 7.1% in an adult contact dermatitis clinic. This increase in prevalence cannot be attributed solely to occupational exposure, medicolegal claims, or temporary "henna" tattoos containing high concentrations of PPD. The rising prevalence of hair dye allergies is a complex issue influenced by various factors. PPD can cause allergic reactions when it is partially oxidized, which happens when it is mixed with an oxidizer (such as hydrogen peroxide) and applied to the hair. The oxidized PPD can penetrate the hair shaft and the scalp and trigger an immune response in people who are sensitive to it.

A handful of studies have linked the synthetic color to health concerns like behavioral disorders and allergic reactions, particularly in children. Animal research also suggests Red Dye 40 could potentially heighten cancer risk. The base PPD is colourless and requires oxygen for it to become a dye, thus PPD hair dyes are usually packaged as 2 bottles, one that contains the PPD dye and the other containing a developer or oxidiser. Darker shades of hair dye products contain higher concentrations of PPD than lighter shades. The darker shades of hair dye are often used by people with naturally dark hair. Some people may only experience skin irritation while for some others, it may get more serious.
On very rare occasions PPD can cause life-threatening anaphylaxis (a severe allergic reaction). There are occasional reports in the media of people experiencing allergic reactions suspected to have been triggered by hair dye. For some people, these reactions have the potential to be severe and, on very rare occasions, even life-threatening. With its anti-inflammatory properties, tea tree oil helps reduce the swelling and rashes caused by contact dermatitis, a common reaction to hair dyes. Steer clear from hair colorants containing ammonia, p-phenylenediamine, sulfates, peroxide, and other known allergy triggers. Look for plant-based products or colorants using only natural ingredients and essential oils.
Another common chemical found in hair dye is para-toluenediamine (PTD), which can be tolerated better than PPD but may still cause an allergic reaction in many people. Hair dye allergy is not a trivial matter, and it should be taken seriously and treated promptly. By being aware of hair dye allergy and how to treat and prevent it, You can safeguard the condition of your scalp and hair and enjoy changing your hair color safely and confidently. Recovering from hair dye allergy and hair loss may take some time and patience, depending on the extent of the damage and your hair growth cycle.
The team then examined the dyes in a test commonly used in the cosmetics industry to determine if a product is a skin sensitizer. Five of the modified dyes were "weak" sensitizers, whereas PPD was "moderate." Another test showed that the new compounds generated a reduced inflammatory response in cells compared to PPD. These results suggest that the new dyes can effectively color hair while also avoiding the potential allergenic and sensitization risks of more traditional ones. Five of the modified dyes were “weak” sensitizers, whereas PPD was “moderate.” Another test showed that the new compounds generated a reduced inflammatory response in cells compared to PPD. It has a reputation of being an allergen for those with sensitive skin or some dry skin conditions. Free of allergy-triggering ingredients like para-phenylenediamine, ammonia, resorcinol, phthalates, and parabens, the Manic Panic hair dye is another superb, hypoallergenic hair dye.
If you notice any redness, itching, swelling, or blistering, do not use the product. PPD is the chemical that is most frequently linked to a hair dye allergy. To find out if the brand contains PPD or any other ingredient that could trigger an adverse response, check the labels. They often appear in the form of contact dermatitis, a red, flaky, itchy rash in the areas of the skin that have come in contact with the dyed hair.

“Highlights and balayage are safer options because bleach does not contain PPD,” Paglionico says. Gloss and toner, which are used after highlights to add shine and soften freshly highlighted hair, typically don’t contain PPD and are applied to the hair, not the scalp. The PPD is usually mixed with peroxide in the dye to alter the hair color. What happens before this reaction is fully complete also makes the PPD more likely to interact with the skin and cause an allergic reaction.
