1. Is this an oil or a serum, and what is the difference?
A bit of both, it is intentionally a hybrid. A hair oil nourishes and penetrates your hair, while a serum primarily creates a smooth, protective layer around it to combat frizz. This product combines the two: it hydrates with camellia and marula oil, but remains lightweight so your hair doesn't get weighed down. For shine and frizz control, that is just a great combination. To be honest: the smoothness comes partly from silicones, so if you are consciously following a silicone-free routine, then this is not the product for you.
2. How much should I use, and will it make my hair greasy?
Less than you think, really. Start with two or three drops; for fine hair, one is already enough. Too much is the main reason hair starts to feel greasy or flat, so it is better to use too little and add more than to use too much at once. Rub the drops between your palms to warm them up first, as this makes it distribute much more evenly. You can always add another drop, but you can't take it back off.
3. On wet or dry hair, and where do I apply it?
Both work. On towel-dried hair, it absorbs nicely as a treatment; on completely dry hair, it works as a finishing touch against frizz and for shine. The most important thing: stay away from your scalp and roots, because that is what makes your hair greasy quickly. Start well below your ears and focus on your lengths and ends. That is where the dryness is, and that is where you want the shine.
4. Does it really help against frizz and for shine?
Yes, this type of product is good at that. It smooths your hair, seals the cuticles, and locks in moisture, which calms frizz and makes your hair shine beautifully. The silicones provide that instant, mirror-like shine; you see it immediately. To be honest: it is a beautiful finish, not a repair from within. For real care, your shampoo, conditioner, and an occasional mask remain the basis; this serum is the icing on the cake.
5. How do I distribute it nicely through my hair?
A few simple things make the difference. Drop the serum into your palm, rub your hands to warm it up so it becomes nice and fluid, and then smooth it from your ends upwards through your lengths. Do you want it very subtle and even? Put a few drops on a wide-tooth comb and comb it through your hair. Don't fiddle with it too much afterwards, just leave it be. That way you get shine without a sticky feeling.
