Why Your Jewellery Is Causing Skin Reactions — And What to Do About It

You take off your necklace at the end of the day and there's a faint green ring on your neck. Or a rash where the clasp sits. Or itching that starts within an hour of putting your earrings on.

This isn't unusual. And it's not in your head.

Metal contact allergy — medically known as contact dermatitis — is one of the most common skin reactions in the world. Nickel, the metal most frequently responsible, affects an estimated 10 to 15 percent of the global population to varying degrees. Everyday jewellery is the most common point of exposure.

What Most Jewellery Is Actually Made From

Most fashion jewellery and a significant portion of mid-range jewellery is made from metal alloys — mixtures of metals combined to reduce cost and improve workability. Common base metals include brass (copper and zinc), white metal, and pewter. These are typically finished with a thin layer of gold or silver plating to improve the appearance.

The problem is nickel. Nickel is added to many alloy formulations because it makes metal harder, shinier, and easier to shape. It is also the most common cause of contact allergy in jewellery globally.

Plating offers temporary protection, not a permanent solution. As the outer layer wears away through daily use, sweat, and washing, the base metal is exposed directly to skin. The thinner the plating — and in most fashion jewellery, it is very thin — the faster this happens. This is why a piece of jewellery that was fine for the first few months may start to cause reactions later.

Recognising a Jewellery-Related Skin Reaction

Metal contact dermatitis typically looks like:

• Redness or a rash exactly where the jewellery sits against skin
• Itching at the contact point, sometimes persistent
• Skin that appears dry, scaly, or thickened at the site
• A green, grey, or dark discolouration — caused by a reaction between sweat and copper in brass
• In more severe reactions, small blisters or weeping skin

Symptoms usually appear within 12 to 48 hours of contact and can persist for days or weeks after the jewellery is removed. In people with an established nickel allergy, reactions can begin within hours of wearing.

Why "Hypoallergenic" Jewellery Doesn't Always Help

The word "hypoallergenic" is almost entirely unregulated in the jewellery industry. There is no standardised definition, no third-party testing requirement, and no legal threshold a product must meet to carry the label. A piece of jewellery can be called hypoallergenic and still contain nickel — simply in a lower concentration than the industry average.

Sterling silver and surgical steel are often recommended as safer alternatives — and they are, for many people. But both still contain trace metals, and for those with strong sensitivities, reactions can develop over time even with these materials. There is no metal-based jewellery that guarantees zero reaction for all people.

The only way to fully eliminate metal contact allergy risk from jewellery is to remove metal from the equation.

Thread Jewellery — Skin-Safe by Nature

Thread jewellery has existed for centuries across many cultures — in macramé, in traditional textile jewellery, in friendship bracelets passed across generations. Its primary advantage over every metal-based alternative is structural: there is no metal at all.

No nickel. No brass. No alloy. No plating that gradually wears away. Thread is a natural material that sits against skin without triggering contact reactions — making it genuinely suitable for all skin types, including the most reactive.

The concern people often have about thread jewellery is durability and design range. With the right knotting techniques and quality thread, thread jewellery can be highly structured, precise, and varied in style. It is not limited to the casual or rustic — it simply starts from a different material base, one that happens to be kinder to skin.

Hair Accessories and the Same Problem

The same issue extends to hair accessories. Most elastic hair ties contain synthetic rubber or latex, and many hair clips include metal components that press against the scalp or hair. Metal springs and coated grips can cause scalp irritation, contact reactions at the hairline, and hair breakage at the points of pressure.

Thread-based hair accessories avoid all of this. They hold without metal components, don't cause the pulling and snagging that damages hair over time, and are comfortable for extended wear.
