Why strong scents can cause headaches

Ever had that awkward moment when you're enjoying the strongest smelling wax melts, only for someone to complain it's giving them a headache?

We've all been there, haven't we? It's the Marmite of the fragrance world, some love it, others hate it.

Keep reading to unravel the mystery behind scent sensitivities. But what smells heavenly to one person can be headache inducing to another. And it's not always about the amount of fragrance oil, even a tiny amount can trigger a reaction if it contains a pesky ingredient your nose doesn't like.

Or maybe you're the one who experiences the headaches and sneezing fits? Fragrance sensitivities are surprisingly common, and understanding the science behind them can be a game changer.

So, what's a scent lover (or a scent sensitive soul) to do? Don't worry, I'm here to help you navigate the fragrant maze!

Why do wax melts give me a headache?

It’s not the wax, it’s the chemistry (and your unique nose!)

Fragrance sensitivities are not caused by the wax itself, but rather by specific aroma chemicals present in the fragrance oils.

These chemicals, both natural and synthetic, are what give each scent its unique character. However, for some individuals, these same chemicals can sometimes trigger a reaction.

Common aroma chemicals known to trigger sensitivities

Geraniol Sweet, floral; found in rose and geranium.

Concentration doesn’t dictate reaction, composition does

I formulate my wax melts for bold, long lasting fragrance throw that fills real UK homes, especially larger rooms where weaker scents disappear fast.

However, it's crucial to understand that the concentration of fragrance oil doesn't change the chemical composition of the scent itself.

It's like for example thinking a triple shot of espresso will make you more jittery than a single shot if you're sensitive to caffeine, the amount doesn't matter if you're already sensitive to the ingredient. The same goes for other sensitivities, such as those to milk, gluten, or even penicillin. Even a tiny amount of the allergen could cause a reaction.

It's important to remember that if you're sensitive to a specific aroma chemical, it could trigger a reaction at any concentration, even in small amounts.

Imagine two wax melts, one with 8% fragrance load and another with 30%. If both use the same exact fragrance oil containing limonene, for example, both melts will contain limonene.

It's also worth noting that sensitisers can be found in up to 90% of oils. This means that even "natural" products can trigger reactions in some individuals.

Yes, strong scents can be overpowering, but bear in mind that individual sensitivities to fragrance vary greatly. It's like perfume, even a beautiful fragrance can cause a headache if overused. If you experienced a headache with one wax melt but not others, it could simply be a matter of personal preference or the specific fragrance.

This doesn’t mean there’s anything wrong with using higher fragrance loads in a well balanced blend; it's just a reminder that fragrance strength is a personal preference, and the chemical compounds in the oil.

Empower yourself: CLP information is your best friend

All Dayas Essence products come with detailed CLP (Classification, Labelling, and Packaging) information, which lists all the ingredients, including any potential allergens. If you have known sensitivities, be sure to check the CLP information before purchasing a new scent. This information isn't unique to wax melts; you'll find similar ingredient lists on perfumes, lotions, and even cleaning products.

Example CLP wax melt labels.

Your safety and enjoyment is my top priority. I carefully select high quality fragrance oils and strive to use the least possible sensitisers. While some scents may contain a small number of these potential triggers, it's often necessary to create the desired aroma. Remember, every fragrance oil is unique. It's all about finding what works for your nose!

Tips for scent-sensitive souls

Start small If you're trying Dayas Essence scents for the first time, start with a smaller piece to test tolerance. You can cut melts to your preferred size.
Keep a scent diary Note any reactions with different fragrances to identify triggers and choose confidently.
Choose wisely Look for transparent brands with detailed ingredient info.
Listen to your body If you experience discomfort, stop using the product.

In conclusion

By understanding fragrance sensitivities, making informed choices, and listening to your body, you can create a fragrant environment that's both enjoyable and safe for you and your loved ones.
