Red Tattoo Ink Linked to Hair Loss and Sweating Issues: A Cautionary Tale

Inflamed Areas of a Man’s Tattoo

University Centre for General Dermatology and Oncodermatology, Wrocław Medical University

A Polish man experienced a severe allergic reaction to the red ink used in his tattoo, resulting in hair loss, cessation of sweat production, and the development of vitiligo. This alarming case highlights potential adverse effects of certain modern tattoo inks on the immune system.

Tattooing is a time-honored practice that traditionally utilized black soot-based inks and manual techniques. Today, electric tattoo machines are employed to rapidly apply colorful synthetic inks across larger skin areas.

Many dyes found in colored tattoo inks were originally formulated for use in printer inks and automotive paints, not for human application. Reports of allergic reactions to colorful tattoo inks have surged in recent years, particularly among individuals with existing immune issues, such as eczema, asthma, and celiac disease. According to research, around 6% of people report allergic reactions that persist for more than four months, particularly with red ink.

The Polish man’s symptoms began four months post-tattoo application on his forearm. Initially, itched intensely, followed by the emergence of a widespread red rash. Over time, he developed hair loss, yellowing nails, swollen lymph nodes, and an inability to sweat. After two years, he also noticed large patches of vitiligo.

Despite consultations with several specialists, including dermatologists and allergists, the underlying issue remained undiagnosed. It wasn’t until the red ink decorations of his tattoo became visibly inflamed that suspicion arose. A biopsy of a swollen lymph node revealed traces of red ink had migrated from the tattoo site.

Due to limited treatment options, the man underwent eight surgeries to eliminate the problematic red ink and apply skin grafts. Post-treatment, while his hair has regrown and vitiligo has stabilized, he still suffers from permanent dysfunction of his sweat glands, presenting a risk of heat exhaustion and necessitating his resignation from military service, as he must frequently spray himself with water.

Despite attempts, dermatologists at Wrocław Medical University could not obtain a sample of the red ink for analysis. However, past studies have identified synthetic organic dyes, particularly azo dyes, as agents responsible for allergic reactions in red tattoos.

The potential health risks associated with tattoo ink are linked to its chronic activation of the immune system. Most tattoo ink remains on the skin, but some can migrate to lymph nodes. Here, immune cells known as macrophages attempt to eliminate the ink but often fail due to its size. This failure leads to a cycle of immune activation, as macrophages transfer the ink to others, perpetuating the immune response. Dr. Sine Clemmensen of the University of Southern Denmark elaborates on this issue.

The Polish man also had Hashimoto’s disease, an autoimmune condition that may have heightened his sensitivity, resulting in the immune system mistakenly attacking his skin.

Emerging research suggests that even individuals without pre-existing immune conditions might face long-term risks related to tattoos. Clemmensen’s findings indicate that having any tattoo color could triple the risk of developing lymphoma, a cancer affecting the lymphatic system.

In January 2022, following another case similar to that of the Polish man, the European Union initiated measures to enhance tattoo safety by restricting chemicals commonly found in tattoo inks with azo dyes. However, legislation in other regions is still pending.

A Captivating and Cautionary Guide to Body Part Replacement and Repair

Our bodies comprise various soft, hard, and intricate components. What should we do when these components fail or don’t meet our needs? Medicine provides several solutions, including dentures, skin, heart, and hair transplants, but don’t expect an instant replacement.

In Alternative You: Adventures in Human Anatomy, popular science author Mary Roach explores the most intriguing historical and current efforts to repair, replace, or enhance our body parts.

These efforts range from dentures designed like mouth piercings, lab-grown anuses, to gene-edited pig hearts, each delivered with a humor that had me laughing, wincing, and holding my breath throughout the pages.

Roach, drawn to the “human element of exploration,” shares engaging tales as she travels the globe to meet surgeons, scientists, patients, and other individuals at the forefront of body modification.

Her bold and often cheeky questions animate these encounters. For example, during a dinner discussion about gut-derived vaginas with her surgeon, she mentions that intestinal tissue generally contracts to aid in food movement.

“That could be advantageous for partners who have penises, right?” she quips. “It’s not overly aggressive,” the surgeon replies, sipping his Chianti.

Roach embraces self-experimentation, visiting a hair transplant surgeon and persuading him to relocate hair follicles from her head to another body area. Her goal? To gaze in wonder at the few long strands that might sprout on her legs. While the transplant fails, she quickly dives into the trials of growing hair from stem cells. Spoiler: we’re not there yet.

One significant innovation Roach covers is ostomy, where surgeons create openings in the abdomen for waste drainage into an external pouch. She speaks with individuals who use stoma bags due to conditions like Crohn’s disease and colitis, which can lead to inflammation and frequent bowel movements, complicating life outside the home. Roach highlights the importance of reducing stigma around ostomies and discusses the remarkable technology supporting this procedure.

As expected from a book on body part replacement, there’s a chapter dedicated to 3D printed organs. Roach approaches this topic thoughtfully, noting that it’s not merely about feeding cells into a printer. Most organs consist of multiple cell types that must be arranged with precise specifications, and printed tissues often lack the authentic properties that remain elusive for researchers.

I highly recommend this book to anyone curious about the human body. However, be advised—some vivid surgical descriptions are included. (If that’s not your cup of tea, feel free to skip the next paragraph.) At one point, Roach compares the tubes of fat and blood pulled from patients to “raspberry smoothies.” Additionally, when a leg implant is affixed to the femur, it sounds like “tent stakes collapsing.”

Such sensory details might not appeal to everyone, but for those willing to confront the raw, sinewy, and delicate reality of our bodies, this book serves as a profound reminder of our complexity and depth. I certainly walked away feeling grateful for all that I have.

From Play to Purpose: A Cautionary Tale on Cybercrime for My Teenage Self

In 2016, a 19-year-old Daniel Kelly faced charges for computer hacking, extortion, and fraud linked to a significant data breach at a British telecom firm, resulting in a four-year prison sentence. Post-release, he has collaborated with over 35 cybersecurity firms to create campaigns and thought leadership pieces.
The reality of digital threats.

As a teenager, gaming dominated my life. I spent upwards of 12 hours daily immersed in it. My focus was entirely on video games, as school didn’t captivate me and my offline social interactions were minimal. Gaming became my world, a means of escape, and my community.

Trouble began around 2011 or 2012 when I was competing in an online multiplayer game and experienced a sudden internet disconnection just before the match. It turned out that my opponent had managed to trace my IP address and launched a Distributed Denial of Service (DDoS) attack against me. This incident sparked my curiosity to understand how it was accomplished, leading me to an online hacking forum—not out of malicious intent, but pure curiosity.

Delving into video game cheating sparked my interest in the workings of websites, prompting me to learn about hacking web applications. I began reporting vulnerabilities to various companies and ultimately gained a position as a security researcher with Microsoft.

What deterred me from pursuing that path was the sense of futility I felt. At that time, formal bug bounty programs—incentives for responsible hackers who discover vulnerabilities—were non-existent, and many companies failed to grasp the concept of responsible disclosure. Consequently, those who reported issues were often ignored or even threatened. For a teenager yearning for acceptance and community, this was transformative.

From 2012 to 2015, things intensified. I forged connections on hacking forums, and the discussions gradually shifted from curiosity to darker topics. I found myself leaning towards cybercrime without fully realizing how far from my initial intentions I had strayed.

Following my arrest, I faced endless legal battles and delays while on police bail for four years.

My first prison experience was at HMP Belmarsh, an environment that felt chaotic and unpredictable. For the initial weeks, I remained hyper-alert—not from fear, but due to the atmosphere. Eventually, you adapt to the prison’s daily rhythm, which also forces you to deeply reflect on your choices. It wasn’t entirely negative, but it was certainly isolating.

The sensation of being liberated can be most simply described as “weird.” You expect freedom to be an emotional high point, but it’s often disorienting. After months or years of being told what to do and when, emerging back into society comes with the expectation of returning to normalcy. Adjusting took time; I had to reacquaint myself with making small decisions and rebuild my confidence.

My sentence included a Serious Crime Prevention Order, which I still abide by more than a decade later. It impacts nearly every aspect of my life, imposing restrictions on my technology use and online activities. The awareness that one misstep could lead to loss of freedom creates a constant tension.

Since being released, I’ve found a way to merge two realms I know intimately: cybersecurity and cyber threat intelligence. Many cybersecurity marketing teams lack technical skills, while many tech experts struggle to communicate their work to the public effectively. I’ve built a bridge between these areas. The same knowledge that once led me astray now serves as the bedrock of my business—an odd yet positive twist.

If you have talents but feel isolated, it’s easy to gravitate toward communities that seemingly accept you but ultimately lead you astray. During my youth, I attempted to apply my skills positively. Had there been a more structured and constructive avenue for young individuals to showcase their abilities, my trajectory might have been different. I wasn’t predisposed to commit typical crimes; it was indeed a valid case where no one intervened to guide my potential for legal use. This lack of guidance combined with innate talent can be hazardous.

Fergus Hay, founder of The Hacking Games, aims to reshape the narrative surrounding hacking from one viewed solely as criminal to one seen as constructive when applied correctly. The partnership between Co-op and The Hacking Games offers young minds an outlet to hone their digital skills toward ethically sound careers—precisely the preventative approach we need. It provides young people with technical skills a positive direction. As a member of The Hacking Games Virtue Community, I strive to guide the next generation in avoiding my past mistakes and using their skills for societal protection.

I would advise anyone passionate about technology to not overlook the opportunities that come from being open about your learning journey. The Internet can connect you with individuals who recognize your potential and provide opportunities. The essential aspect is to focus your energy on mastery rather than mischief. Be mindful of the motives of those around you. If someone suggests that laws are irrelevant or that all laws are inconsequential, it’s a warning sign. The boundary between curiosity and crime can blur quickly without guidance.

My thoughts on what advice I would give my younger self continue to evolve. The obvious response would be, “Please don’t.” Yet, the reality is that everything I experienced has fundamentally shaped who I am and my current endeavors.

Still, I would advise my younger self, “Don’t cross that line.” Avoid threatening or extorting businesses—that remains my greatest regret. I’d also emphasize the importance of considering the outcomes and realizing how many lives are impacted by rash actions. While curiosity itself isn’t wrong, the way it was wielded was flawed.
