Okay so I have used my fair share of hair products in my day. I have tried countless top of the line professional oils and serums (Moraccan Oil, Wella Oil Reflections, Josie Maran Pure Argan Oil, etc.). It was either $$$$, too light for my hair that I constantly had to apply it, or too heavy and weighed my hair down. My stylist recommended the Sebastian Dark Oil and promised me that I was going to love it. WOW!! Was she right!! I wash my hair every 3 days and apply 2-3 pumps (very long thick wavy hair) and blow dry and style my hair. Not only is my hair shiner, smoother, and overall healthier, I don't have to reapply this product until my next wash three days later. My hair stays smooth and shiny and I am able to restyle my hair each day without it drying out. My hair is so moisturized and healthy! This product is everything I have been searching for! There is not a better oil out there!!
I have curly hair so I use an oil every time I wash my hair. I was excited to use the oil because I have had great experiences with Sebastian products in the past. The oil smells great but, doesn't work any better than the less expensive oils that I have been using. This one is not one to blow the bank on ladies!

This is by far my favorite hair oil. The smell is amazing. I have fine straight hair and I use this as a last step of styling and it makes my hair soo amazingly smooth and frizz free. It's super concentrated so a little goes a long way and the bottle will last me forever so the price really pays off. 10/10 recommend!

I have thin fine hair, but I also have extensions that need a lot of hydration. I have tried a LOT of oils & this is my go to, absolute favorite that I can't live without, but you have to use it correctly esp with fine….￼
For thin hair, I would suggest putting a small amount in when it's wet. For dry hair you need to use a VERY small amount, warm it in your hands so it thins out & finger comb it in. If you use too much it will be greasy. Both ways work great for thicker hair too.
My favorite way to use this product is after I curl my hair I rub a little in my hands & finger comb it through. The oil takes my curls to a new level of shine with no flyaways. I do the same thing to freshen up next day curls.
Because you only need a small amount, this lasts forever! My last bottle lasted about 10mo. maybe more. Oh, did I mention how great this smells!!!!!

I was super hyped to get this " oil". It is NOT as wonderful as people are describing it. I have fine, thin, frizzy hair, all it does is make my hair greasy. I've tried every technique for applying. If you have an interest in this product, IT IS NOT CARRIED IN THE STORE. I will now have to return the product. A BIG NO!

I use daily for a great shine every other day!

My hair stylist started using this on my hair and just from the smell alone I was hooked. Then I saw how it really smoothed my hair and controlled frizz. I have long, thick, coarse hair and not many hair products penetrate my hair like the dark oil does!! I used it while in Nashville in the summer and my hair was smooth all day. I was shocked! I use it on wet hair pre-style and also as a finisher with the silkening mist from Sebastian. If you have thick hair that frizzes easily, RUN and get this. You won't regret it.

I love this dark oil. I bought the travel size to test it out and see how I liked it and how it wore on my hair before committing to a large bottle. I've tried several different hair oils. Some I found were alright and others made my hair look and feel like I hadn't washed it in months.
The Sebastian Dark Oil has to be the best hair oil I've tried that leaves my hair looking and feeling healthy, shiny, and beautiful. I love that it gives my hair a natural shine rather then an unwashed oily shine and it smells INCREDIBLE. I love it and will continue to buy more.
Jerrica from Washington
Smells great and you truly only need a pump or two. Absorbs into my hair and does not feel heavy.
Desertdweller from Phoenix
I purchased the small size when it was a beauty steal. This is no better than a popular drug store product. It's not an oil, either, and it's texture is more like a glossing serum. The smell is woodsy and more like something of a mens cologne. It wouldn't repurchase. There are better products at this price point, but there's also better products that are cheaper. I don't understand the hype.
Kayla from Midland Mi
Best oil I've ever used. It's not sticky like most and it glides through your hair so easy.
BabsG from Harrisburg
I've been using Sebastian Dark Oil for years and I love it. I use it as my hair has been dried and styled. I put a TINY drop in my palm and rake through my hard. I also use it between shampoos when I just need to bring back a bit of shine. My current bottle has lasted three years.

i have been trying to find something to help my dry hair in the winter i got this and the deep conditioning mask and can easily say i love this more than olaplex. Cannot wait to get the shampoo and conditioner next!

This product visibly transforms my hair to looking healthy and shiny! My holy grail of a hair product!
deedee from bucks county, pa
this has no fragrance at all and I would love to know where are you guys are smelling it at? Mine is surely a dud...DUD...it does leave a nice soft residue on my hands and that is about it...highly disappointed...

Having wavy hair that frizzes easily, I've started experimenting with hair oil to control frizz, and to soften my hair texture. Dark Oil is one of the best oils I've tried. It smells wonderful and isn't flowery so my husband likes wearing it too. But the best part is how Dark Oil improved the texture of my hair. After 3 weeks of use, it's silky and soft. It's Akari frizz-free. I use it when my hair is wet or dry, and a little goes a long way.
Sara from NY
I saw so many reviews talking about the scent, I wasn't sure what to expect when I got it. I was surprised by it, it smells good but not in the way I expected. It reminds me of how I would imagine your hair would smell after working a day at hollister or ambercrombie and fitch.
Quality wise it's nice, but it's heavy in silicones which aren't necessarily bad for your hair but they artificially make it feel better than it is. I probably won't buy it again but I'm not upset with the purchase
Ann from Los Angeles
I gave in and bought this product after reading the reviews and I was not disappointed at all. I've been using it after I shower on damp hair and it leaves my hair so soft, manageable, frizz free and overall healthy looking / feeling. I have wavy/curly hair & it doesn't weigh my curls down at all. My hair was so easy to detangle too. Worth it
Rehk from Orlando
The first two ingredients are silicones… the name Dark Oil is a lie. Got to read ingredients to see what you're paying for. That's some expensive plastic.
Kat from CT
Subpar product left my otherwise healthy, normal hair feeling greasy. I don't see the hype. Found out after I bought they test on animals, and horribly so. NOTHING is worth that, not even good hair. Do not recommend.
AComment from Big Sky
Not only does my hair look and feel amazing it smells better than ever with a gorgeous shine! It's a must have and highly recommend!
Yasf from Miami, Fl
I really like it, my hair smell and looks great!
AJ from Maine
I saw this product on TikTok and went back and forth with spending the money, but it is worth every single penny!!! It takes very little to see results! I barely use a light pump and I have very long hair. It makes my hair so soft and shiny!
Santana from Kentucky
For context, my hair is unmanageable. I damaged my hair horribly in summer 2016 after several at home bleach treatments. Even after 5 years and several big chops my hair is still not the same. I had beautiful curly hair and now I have semi-wavy hair with some straight pieces, some curly pieces, and soooo much frizz and dryness. I have tried so many products to feed life into my hair again. Other oils make my naturally dark hair look so oily and nasty. This oil though-amazing. I put this in my hair from mid length to ends while my hair is 75% dry. Then, when styling at 100% dry I put half a pump in my hands and put it through the top of my hair to smooth frizz. This truly is light weight and does not make my hair look greasy even after using it for refreshing after 3-4 days. Along with Olaplex 3, this dark oil has literally saved my hair and I could not be happier that I found this!
Rach from Michigan
I got this on sale during the hair event and I love it, I have fine curly hair and love using this before blow drying and after. This will stay as one of my staples.
