Hi
Thank you for your review; I'm sorry to hear you didn't like the product.
The Macadamia and Argan Oil is a carrier oil, so nothing is added to fragrance it. Argan can have a really potent natural scent and it is personal preference, if you like it.
What we'd suggest is if you'd like to make it smell nicer, add a couple of drops of pure essential oil (really, only a couple) to the warmed carrier oil. Lavender can be very moisturising for hair, and Ylang Ylang is often used in hair perfumes.
With oils, depending on the porosity of hair, sometimes you need to give a second wash with shampoo to fully rinse it out. If your hair is quite thick and soaks up products, generally one rinse with water is enough; but hair that is thinner or hasn't fully soaked in the oil you will need to shampoo it out. Using a gentle shampoo, like the Odylique range, will help you maintain the benefits of the oil as well as stopping hair feeling greasy.
With Kindest Regards
