Sebastian Professional Dark Oil Lightweight Hair Styling Oil | Nourishing Blend of Natural Oils for a Smooth, Sleek Finish

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.

I love the smell... strong and good smell... some people say it is too strong but I really love this one and makes my hair shine and smooth

hair feels so soft. and looks healthy

I went and told my hairstylist about this product when I started using it and was told by them that this is a good product to use, which is right of the bat a great thing to hear. The product is thick and oily in texture leaving behind a slightly sticky residue on your fingers when applying. It smells rich and nutty/woodsy to me, suiting a more sophisticated style. It’s true that the bottle is fairly small (~5in/13cm tall), but the product has lasted be a very long time as not much of it is needed for the effect. I used 1/2 - 1 pump when applying it to my hair (it’s naturally oily and fine so too much product weights down the volume). Overall, despite the high price point I’d continue to buy it in the future and use it as a special occasion product or wait for it to go on sale (they’ve done 50% off before) and buy it then to use more regularly.

I love this product! I bought this when I got my hair extentions put in. It smells amazing, it leaves my hair shiny and has definitely helped keep my hair in great shape. The price for the size is great. About to buy a 3rd bottle!

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.

The oil will last forever, I usually buy, Wella hair oil. But since I found the, Dark Oil line, I buy nothing but! My hair is healthy and has a nice sheen to it. I recommend using the shampoo and conditioner with the oil for the whole experience.

My hair tends to be very dry rather than oily. It's professionally color treated from dark espresso brown to a blonde and the texture is naturally full and heavy. So by the time I return to the salon, the ends are always looking a little unhappy. I like to use this oil to help offset any stress going on in my hair as it helps seal in some of the moisture it always so desperately needs. The scent is divine and I only need to use a small, quarter sized pump to work through my shoulder length strands.It does not leave any greasy build up, but makes it much more sleek, shiny and polished. This is a lifesaver on days where my hair doesn't want to behave and I use it on wet or dry hair.For the value I get out of it, it's definitely worth the cost as I find all the Sebastian products I use to be salon level quality and satisfaction.
