Nickel Tested and Nickel allergies

When looking at cosmetic product labels, you've probably come across the words " Nickel tested <1 PPM ." But what does this mean?

Nickel Tested <1 PPM indicates that specific analyses have been carried out to ensure that the nickel content in the product, if present, is below the infinitesimal level of 1 PPM, or one part per million . This is, in fact, the value recognized as completely safe for cosmetic use, even for people with severe nickel allergies.

A Nickel Tested < 1 PPM product is, therefore, a product in which the presence of nickel is below the minimum risk threshold.

All our cosmetic products are Nickel Tested, and you can verify this by looking at the label.

In fact, you will find this logo on them:

Are hair herbs (neutral and dyes) nickel tested?

All our herbs are tested for various elements, including nickel, to ensure we always maintain controlled levels. The values typically found are a few parts per million (some around 2-3 ppm, others 4-6 ppm), which indicates truly infinitesimal quantities in our plant powders, though not always below the absolute safety threshold.

In the food sector (a different topic, but one that can help us provide a general idea), countless foods contain significantly higher amounts of nickel: nuts, cocoa, legumes, and even many types of vegetables. Plants have roots in the soil, and therefore absorb nutrients from it, including all the mineral salts and metals present (even if in infinitesimal amounts).

Of course, there may also be batches of plants with nickel levels below 1 part per million, depending on the harvest, the season, and the soil in which they are grown from year to year. This means, however, that the conditions may not always remain the same at the next harvest.

Unlike traditional cosmetics (detergents, creams, etc.), which have a standard formulation that doesn't vary even with batches, it's not possible to consistently maintain a nickel level below 1 ppm for plants . This means that the words "Nickel Tested <1 ppm" cannot be reported on labels, as this may not be true for all batches.

For reasons of correctness , we have therefore decided not to report this claim on the herbal bags, even though all the necessary analyses are carried out, aimed at always guaranteeing controlled values and minimum thresholds.

What to do if you have a nickel allergy?

If you have specific allergies and aren't sure how your skin might react to a particular herb or blend, we always recommend doing a small home skin test to assess your skin's tolerability. If you have very sensitive skin, or have specific skin conditions or conditions, it's always best to consult your doctor or a specialist.
