Imagine your favorite tattoo turning against you, triggering unexpected allergic reactions that leave you unable to dye your hair or even tint your eyebrows without excruciating pain. That's exactly what happened to Victoria, and the surprising culprit was her own body's response to the ink beneath her skin.
Victoria Privett, a content creator with a passion for equestrian videos and a love for meaningful tattoos, is currently undergoing tattoo removal – not because she regrets her ink, but to safeguard her health. Each of her seven tattoos holds a special place in her heart, making this decision all the more difficult.
The ordeal began a month after Victoria got a large, ornate phoenix tattooed on her hip. She applied a hair dye she'd used countless times before and, “within minutes of applying the dye to my head, my scalp started tingling, then burning,” she remembers vividly. She quickly washed it off, dismissing it as a fluke. But here's where it gets controversial... could something seemingly harmless, like hair dye, really be connected to a tattoo?
Two months later, the same agonizing experience repeated itself, only this time with even greater intensity. "The burning was unbearable," Victoria recounts. "It was instant and very painful. I had to stop and wash it off early.” The aftermath left her scalp inflamed and sore for days.
The plot thickened a few weeks later when Victoria decided to tint her eyebrows, something she'd done regularly without issue. “I’d done this before too and it was always fine,” she says. “But this time, my brows swelled, then itched so bad they bled– then scabbed over. I was puffy for days. It made no sense. I’d always dyed my hair and tinted my brows. Why was I suddenly reacting like this?”
The answer, surprisingly, lay within her tattoos.
Dr. Jonathan Kentley, a consultant dermatologist based in London, confirms that tattoos can indeed trigger allergies, either to the tattoo itself or, unexpectedly, to substances like hair dye.
The reason? “The process of tattooing places chemical substances permanently into the dermis – a layer of skin that is closely monitored by the immune system, and your body recognises it as something foreign,” Dr. Kentley explains. Think of it like this: your body's security system is constantly scanning for intruders, and in some individuals, it flags the tattoo ink as a potential threat.
“In some people, the immune system recognises components of the ink as harmful and mounts an allergic response.” And this is the part most people miss... it's not always an immediate reaction.
Dr. Kentley clarifies that this is typically a delayed-type allergy. “Meaning it may not appear immediately – you won’t necessarily react when you have the tattoo. Reactions can develop months – even years – after the tattoo was done, and is sometimes triggered by factors such as sun exposure, infection, trauma or changes in immune health.”
This sensitization doesn't just affect the tattoo itself. The permanent presence of the ink can cause the body to become hyper-sensitive, reacting to similar chemical components it encounters elsewhere, like in hair dye.
The more tattoos you have, the greater the risk. As Dr. Kentley, also a spokesman for the British Skin Foundation, puts it: “If someone is already allergic to a tattoo pigment, any amount of ink could trigger a reaction. However, the more of the pigment delivered into the skin – i.e. via large or multiple tattoos – the greater the risk of you becoming sensitised to the allergen, and in turn developing an allergy.”
The likelihood of developing an allergy varies depending on the tattoo's color.
“Red ink is the most notorious,” Dr. Kentley states. “Historically, red pigments often contained mercury sulphide, and although modern inks may no longer use mercury, many still rely on complex dyes or metal-based compounds that are able to stimulate an allergic response. As a result, red tattoos are disproportionately associated with chronic itching, swelling, scaling and raised lumps that can persist for years.”
A 2020 study published in the journal Contact Dermatitis supports this, concluding that red ink tattoos are particularly prone to triggering allergic reactions. The findings were based on an analysis of over 100 skin biopsies from people with tattoos.
But red isn't the only culprit. Dr. Kentley notes that black tattoos are also frequently implicated in delayed allergic reactions because many contain para-phenylenediamine (PPD) – a chemical dye commonly found in hair dyes and black henna tattoos.
“Not all black tattoos will contain PPD, but it is a very common allergen – often found in hair dyes and temporary tattoos – which people can develop an allergy to even despite multiple exposures in the past,” he explains. “This is why patch tests are usually recommended.”
“People sensitised to PPD – which can occur with repeat exposure to hair dye, too – appear to have a higher risk of reacting to certain tattoo pigments later on.”
Yellow and orange inks aren't immune either. These colors can cause photosensitive reactions that worsen with sun exposure, according to Dr. Kentley. “This is usually related to the yellow pigment cadmium sulfide – when exposed to light, this can become phototoxic which means it produces compounds that can damage skin cells, causing inflammation.”
Furthermore, some individuals may have allergies to metals like nickel, cobalt, and chromium, which can be found in tattoo ink pigments.
All of this information might come as a shock to the millions of tattooed individuals worldwide. A YouGov poll in 2022 revealed that a quarter of people in the UK have tattoos.
Many are unaware of these potential risks when they first decide to get inked. Victoria, who resides in Hampshire with her husband, got her first tattoo at the age of 18.
“I loved it and it had meaning to me – and within two years, by the time I was 20, I had seven,” she says.
Her last tattoo, a particularly intricate design, took three days to complete and incorporated a significant amount of red ink.
It wasn't until months after her eyebrow tint reaction that Victoria learned from a friend about the potential link between her tattoos and her allergic reactions.
“I was wearing a hat because my head was still so puffy, itchy and painful,” Victoria recalls. “My friend asked why I was wearing a hat, and I explained what had happened, to which she replied: 'Did you know tattoos can cause hair dye allergies?' I’d had no idea.”
Victoria believes that the sheer volume of ink used in her last tattoo likely triggered the allergy. “This was the last tattoo I had and the most time-consuming, so it can only be that which brought on the allergies,” she says.
Treatment for tattoo-triggered allergies is “challenging,” says Dr. Kentley, “because the allergen cannot easily be removed from the skin.”
Mild reactions may respond to topical steroid creams, which can help reduce inflammation and itching.
More persistent cases may require steroid injections into the affected area or short courses of oral anti-inflammatory medication.
“Unfortunately, some reactions are resistant to treatment and continue to flare intermittently,” Dr. Kentley cautions.
And laser tattoo removal, while an option, is not without its own risks.
