As social media and the internet become a bigger part of everyday life, many of us are learning more about what we put in our bodies, including the hidden risks in menstrual products. Most conversations focus on what’s in a tampon, but it’s just as important to ask: what’s coming out of it?
What is Fiber Shedding?
Fiber shedding is a widespread phenomenon that occurs when tiny strands of material from menstrual products detach and remain inside the body during use. This issue is most commonly associated with traditional tampon brands, which are typically made from non-organic cotton, rayon, or blends of both. Tampons made with rayon or a rayon cotton blend tend to shed more fibers than those made with 100% organic cotton. It is a semi-synthetic fiber derived from cellulose and is often chosen for its high absorbency, but can break down more easily during use. These microscopic fibers can originate from the absorbent core or outer layers of these products.
Fiber shedding isn’t just about loose strands; it’s about what those fibers may be carrying. Traditional menstrual products often contain 20 to 30 chemicals, including fragrances, dyes, preservatives, and even microplastics. Although fiber shedding is rarely discussed, it raises valid concerns regarding menstrual health and safety.
Risk in Everyday Traditional Products
The daily use of fiber-shedding tampons can lead to cumulative fiber buildup in the vaginal canal. These fibers may interfere with vaginal health and day-to-day care, contributing to irritation or discomfort over time.
The primary concern with fiber shedding is the potential health risks it poses. When fibers are left behind in the vagina, they may cause irritation or inflammation of the delicate and highly absorbent vaginal tissues. This irritation can lead to discomfort and an increased susceptibility to infections. In some cases, these residual fibers may contribute to more serious conditions. For example, Toxic Shock Syndrome, a rare but life-threatening condition, has been linked to tampon use. Some researchers suggest that fiber shedding may play a role by creating a suitable environment for the growth of harmful bacteria such as Staphylococcus aureus. Other risks include vaginal irritation and microtears, increased risk of infections, and biofilm formation, which is linked to recurring infections.
Despite these potential risks, fiber shedding remains poorly regulated. In many countries, brands are not required to disclose the full list of materials used in their menstrual products, nor are they obligated to conduct specific tests for fiber retention. There is currently no global standard for tampon fiber retention, leaving consumers without clear guidance on which products pose the lowest risk.
To reduce the risk of fiber shedding, there are several proactive steps you can take. One of the most effective is choosing 100% GOTS-certified organic cotton menstrual products. Organic cotton is typically less processed and has longer, interlocking fibers, which makes it stronger and less likely to shed compared to rayon-based alternatives. In contrast, rayon tampons, with their shorter, straighter fibers, are more prone to breaking down and leaving strands behind during use. Avoiding fragranced or chemically treated products can also make a difference, as these additives can heighten irritation and disrupt the vaginal environment.
Our Solution to Fiber Shedding
Iris + Arlo products are menstrual products designed with your health and safety as a top priority. Our tampons are uniquely engineered with a built-in security veil, woven in 100% GOTS-certified cotton. The veil acts as a protective layer designed to prevent fiber detachment during use. This veil creates a physical barrier that holds fibers in place, offering a significantly safer alternative to traditional tampon designs.
Fiber shedding isn’t just a material issue; it’s a design flaw. Without a mechanism to contain fibers, even organic tampons can shed; this is where the security veil becomes a critical advancement in menstrual product safety.
The primary purpose of the veil is to prevent loose fibers from detaching when a tampon is inserted, worn, and/or removed. It acts as a physical shield that holds the absorbent material in place while still allowing the tampon to function effectively. Without a veil, fibers are more likely to break away, especially when the tampon expands and contracts inside the body or during removal of the tampon. The security veil helps address risks not by changing what a tampon is made of, but by changing how it works.
Conclusion
Fiber shedding is a real issue, and one that’s often ignored. It’s one of those quiet design flaws that doesn’t make headlines but deserves more attention. Between synthetic blends, chemical additives, and loose fibers, traditional tampons can introduce more than what’s needed. While organic cotton is a good step forward, it’s not a complete solution on its own. That’s why design matters. With built-in safeguards, we can rethink what safe and thoughtful period care actually looks like.
