An ideal method to care for hair, is to mix fixed oils with the oils extracted from herbal seeds. For instance, rosemary, oregano and garlic oils are naturally very strong, and if you directly use them on the hair roots, your scalp might show some reactions, or burn. Ideally, you should add only a few drops of these oils in fixed oils such as sesame, olive or almond oils. If you intend to use rosemary oil, apply it on a clean scalp. If you will use garlic oil for your hair care, apply it on greasy hair – best if you have not washed your hair in the last two days. Mix the natural herbal seed oils, particularly the aromatic and strong ones, with virgin olive oil or fixed oils like sesame oil.
