Ingredients Explained

These ingredients are found in both products.

Ingredients higher up in an ingredient list are typically present in a larger amount.

Masking, Perfuming

Parfum is a catch-all term for an ingredient or more that is used to give a scent to products.

Also called "fragrance", this ingredient can be a blend of hundreds of chemicals or plant oils. This means every product with "fragrance" or "parfum" in the ingredients list is a different mixture.

For instance, Habanolide is a proprietary trade name for a specific aroma chemical. When used as a fragrance ingredient in cosmetics, most aroma chemicals fall under the broad labeling category of “FRAGRANCE” or “PARFUM” according to EU and US regulations.

The term 'parfum' or 'fragrance' is not regulated in many countries. In many cases, it is up to the brand to define this term.

For instance, many brands choose to label themselves as "fragrance-free" because they are not using synthetic fragrances. However, their products may still contain ingredients such as essential oils that are considered a fragrance by INCI standards.

One example is Calendula flower extract. Calendula is an essential oil that still imparts a scent or 'fragrance'.

Depending on the blend, the ingredients in the mixture can cause allergies and sensitivities on the skin. Some ingredients that are known EU allergens include linalool and citronellol.

Parfum can also be used to mask or cover an unpleasant scent.

The bottom line is: not all fragrances/parfum/ingredients are created equally. If you are worried about fragrances, we recommend taking a closer look at an ingredient. And of course, we always recommend speaking with a professional.

Limonene is a fragrance that adds scent and taste to a formulation.

It's found in the peel oil of citrus fruits and other plants such as lavender and eucalyptus. The scent of limonene is generally described as "sweet citrus".

Limonene acts as an antioxidant, meaning it helps neutralize free radicals.

When exposed to air, oxidized limonene may sensitize the skin. Because of this, limonene is often avoided by people with sensitive skin.

The term 'fragrance' is not regulated in many countries. In many cases, it is up to the brand to define this term. For instance, many brands choose to label themselves as "fragrance-free" because they are not using synthetic fragrances. However, their products may still contain ingredients such as essential oils that are considered a fragrance.

Alpha-Isomethyl Ionone is a fragrance. It can be synthetically created or naturally occurring.

The scent of Alpha-Isomethyl Ionone is described as "flowery" but can also be "woody".

Naturally occurring Alpha-Isomethyl Ionone may be found in Saccharomyces cerevisiae, or the yeast used to make wine and bread.

The term 'fragrance' is not regulated in many countries. In many cases, it is up to the brand to define this term. For instance, many brands choose to label themselves as "fragrance-free" because they are not using synthetic fragrances. However, their products may still contain ingredients such as essential oils that are considered a fragrance.

You may know this ingredient as argan oil. Argan Oil has antioxidant, hydrating, and soothing properties.

Studies have shown argan oil can help fight again radical damage from the sun. This makes it effective at preventing hyperpigmentation.

Large amounts of vitamin E found in argan oil helps the skin retain water. Argan oil also contains fatty acids such as linoleic acid, oleic acid, and palmitic acid. It is also a good source of lipids.

Another benefit of argan oil is skin-soothing. It can help reduce inflammation-related skin symptoms.

Argan Oil is effective at regulating sebum production in pores. This can make it effective at treating hormonal acne.

Traditionally, argan oil was used for its antibacterial and antifungal properties. However, argan oil contains fatty acids that may make it not fungal-acne safe.

Argan Trees are native to Morocco.

Best hair oil ever. I have tried many others - Olaplex, argan oil, Fino, schwarzkopf, Paul Mitchell, Elvive (supposed to be a dupe but oh god it’s horrible).

It’s light weight, smells elegant and leaves my hair super soft and minimises frizz.
I apply on damp hair after NAK replends leave in cream, this combo is perfect for me.

So sad that they’ve reformulated and jacked up the price with Show more
