Excellent shine-producing oil that also tames frizzy hair. I use some sparingly at night to give my hair extra moisture overnight. But it's also great for refreshing your hair with shine and sleekness. A little goes a long way. Pleasant scent - sort-of gourmand-smelling.

So glad that my sister introduced me to Sebastian Dark Oil. I have been using it for atleast a couple of years to add shine and protection. I only need a pump or two. It lasts a long time. My hair always feel so silky after putting the oil in my hair and it smells so good. This oil is very light and does not sit heavy on your strands. My hair has shine without looking greasy. This is a hair product that I definitely recommend. It’s worth the cost!

I am a Sebastian fan, and have been using a treatment for my dry ends for a while, so when I found my new favorite Sebastian shampoo here on Amazon, it only seem right to try out the ends treatment in that shampoo line. I am quite pleased with this treatment to far - it has been a 6 months. My hair is getting fuller at the ends - Yea! That is the goal. It also seems to make my hair easier to comb - although I started the shampoo, conditioner, and ends treatment all together, so it may be the entirely new regime and not just one product. My ends are less dry than with no treatment and this treatment has a gel like consistency, rather than an oily consistency like my previous treatment, I like this better. It does not take much - I use only 3 pumps for my fanny length hair. I did experiment, but more is not always better - too much (6 pumps) made my hair feel odd, gummy?, not smooth, so use a light hand, a little is all you need. It is a bit pricy, but since you only need a little each use, it lasts a long time - this is my second bottle, I bought the small one first, then the larger size - I kept the small bottle and refilled it for my travel case😉 since I don't intend to go without this even when traveling. As I air dry my hair, I can't speak to heat protection but this new regime has increased my hair's shine and general healthier and thicker feel and appearance. Will be buying this again! I have actually put it on subscription, so I won't run out.

I gifted another more expensive brand to my cousin. Hint: dust. Caught a half price sale and replaced it with Sebastian. And LOVE it! I started to massage this into my husband’s hair just about every day. He loves it now. It lasts a long time. Makes the hair compliant and refreshed, not greasy at all. And it smells great. Use it on wet and dry hair. Buy it. It’s worth it..

This is a lightweight hair oil that makes my hair so shiny and seems to control frizz. I’ve been using it for a few years now. I’ve tried other products, but they seem heavy in comparison.

it smells like the original. Satisfied up to this point. People are complaining about expiration dates. This is how I understand it. That date on the box is day it was made, not an expiration date. Gallon jugs of water in grocery stores are the same way, date when the water was put in the jug, not the expire date. Now, how long this product is good for should be at least a minimum of five years if protected. Cool, dry, storage place. Not in the bathroom. It's like perfume because of the scent it has in the oil. The one i ran out of was five years old and scent was still good. It Aegean oil I think. I am not sure if the package was intended to be wrapped in cellophane wrap. Mine didn't have it either but product appears fine and I'm pretty good with fragrances. I know in a store where you purchase product, it doesn't even come in a box, just the bottle. Most things do come wrapped. you just never know. But if it did come with wrap, I'd sure like to know why it wasn't on there when I received mine. But like I say, it does not appear to be tampered with. Even if it did come in cellophane wrap, it can be removed and re-wrapped. That is pretty easy to do actually with the right tools. The reason I didn't give this a five was it didn't come wrapped. Otherwise I'm 100% happy to this point. Good product and great fragrance.

Sebastian Dark Oil is a true wonder in hair products! First, the smell is like the sandalwood oil perfumes I used to get at bohemian gift shops… delightful! Second, my hair, which requires daily if not 2X daily heat brushing, is silky and smooth with no frizz or flyaways. It isn’t greasy either, but then again my thick and sometimes a little coarse hair drinks up oils in no time. Finally, it takes such a small amount since it is so very rich. *I immediately applied it to dry, not-yet-heat-brushed hair upon receiving it and was quite impressed. I look forward to using it post shower on its own as my hair already had a generous amount of Elizavecca oil in it.
