Argan oil has a similar aroma to olive oil, with a hint of sourness. Overall it's a light and subtle fragrance, but if you're using it as a carrier oil, you may want to double-check that the fragrances will be complementary.
Argan oil that isn't pure will sometimes be overly sour, but since WE only uses pure and unaltered oils, this won't be an issue. Because the fragrance is fairly subtle and the oil itself is gentle, it makes a great carrier for other essential oils.
For practical usage, argan oil is great for drawing moisture into both the skin and hair, which is why it's found in many lotions and conditioners. It's also great for preventing sun damage, which is important year-round.
