For Peas who use Moroccan oil products on their hair...

It's good for dry hair and cuts down on frizz without being too weighty. I just rub a few drops into my hand and rub onto my wet hair. My stylist overdid it and my hair looked smooth but flat.

I'm not sure how it would be for thin/wispy hair.

I use the Moroccanoil brand, "light" - it's simply a very lightweight oil or serum-like liquid. 1-2 drops rubbed on my hands and then through the ends of my hair - avoid your scalp. It makes it non-frizzy and smooth, and it smells really good.

I use it in a "hair oil" form... looks like oil. A small amount in the palm of my hand, rub hands together then rub both hands through my hair. My hair is extremely dry and curly. The oil helps control the friz so it lays in nice curls/waves instead of looking frizzy. I don't k now what form you need it in.

I use the bottle of oil and like other above have said, I rub a small amount in my palms and apply to the ends of my damp hair. I use it once in a while on dry hair, if I need to keep wisps down.

I use the cream lotion. Just a drop and run through my hair before I blow dry.

That wasn't caused by the oil itself. Her problem was caused by the other ingredients in the shampoo and conditioner. The oil itself is a very light oil but start adding in other ingredients you can get build up from them.

and the poster above me is right that it does have a rather strong and very distinctive smell.  I happen to like the smell but not everyone does. 

I agree with the others, Moroccanoil probably isn't going to do anything good for fine/whispy hair.
The oil is an actual oil, it's thick and greasy and heavy.

I have thick naturally curly hair that tends frizz and it is also highlighted. I use the oil because it weighs my hair down and tames the frizz...even then I was initially a bit worried about actual oil in my hair would look - but my hair seems to just soak it right up.
I did once use a sample of another brand and that one make it look like I had greasy hair, but the original Moroccanoil (the one in the photo above) doesn't do that and it's the one I've used for several years now.

I doubt this would be the right product for you - or you'd just need to use a tiny amount (literally a few drops) and work it through really well. But it's an expensive trial if you don't like it! Of course you could always send the rest to me if that happens....

I have fine, thin, whispy hair and I still use Moroccan oil. I use the light version, use a tiny amount rubbed between my palms, and I apply it to the mid point to the ends of towel dried hair. Once I blow dry my hair I may also use a tiny amount to take the baby hairs at the crown of my head. I couldn't get away with a full pump of the stuff, but used sparingly it is really nice. It takes me a year to go through a bottle so it is worth the price tag.
