My hair oil has changed colour, is this normal?

The shift in colour is part of the natural process of oxidation with organic oils and is a direct result of the absence of synthetic dyes or additives in our product. Please be assured that this colour variation doesn't compromise the oil's effectiveness or its benefits for the hair and scalp. To prolong the original colour, we recommend storing the oil in a cool place and always ensuring the cap is tightly sealed.
