This is the best hair oil I’ve ever used and I’ve tried a ton
This oil is AMAZING! It’s a little pricy but worth every penny in my opinion. It smells so so so good. It doesn’t weight down your hair or make it look greasy. It gives the perfect amount of shine and helps with frizziness in the humid summer months and it gives a great amount of moisture during the dry winter months. A little goes a long way so I can usually make one bottle last like a year so even though it’s a little expensive, it’s not so bad when you realize how many times you can use it before needing more. I’ve been using this stuff for years. I originally got it in a subscription box, I think in Birchbox, and I immediately fell in love. If you’re on the fence about ordering, I say go for it. You won’t regret it!

My Favorite Hair Product
I love this hair oil!!! I got it as a sample in a birch box YEARS ago. I just started using it again and it made my hair so soft and smooth. This product smells sooooo good too. Every single time I wear it I get compliments. I hugged my friend and he texted me later to say that I smelt good. I had no perfume on, just the hair oil. I also like how you can twist the top of the pump to lock it if you are traveling and are scared to get oil everywhere. When you pump the oil out, a good amount of product comes out. I found that I didn’t need to use that much. However, my hair has a slight wave to it and I found that when I use the oil, it seems like it makes my hair less wavy. I took a before and after picture of the oil. I was laying down and my hair was all frizzy, so I thought that would be a good example.

Worth every cent.
Best hidden secret to the most luxurious, soft, shiny hair. Serum is so light and spreads so nicely. The smell….is perfect!!! I use 2 pumps on damp hair then 1-2 more after done styling. A sale price would be nice though! 😉

So great for frizz and humidity
This stuff is so great at keeping my hair less frizzy in the hot Texas humidity! I wash and condition my hair and then put one pump of this on my hands and comb that through my wet, towel dried hair with hands, then blow dry, then put one more pump on my hands and comb that through my hair again after drying. It really helps to control the frizz and keeps my hair soft and more tangle-free. I have a lot of very fine hair and this doesn’t weigh my hair down too much or leave it looking oily or limp. Just make sure to lock the top AND keep it in a ziplock bag when you travel so it doesn’t get all over your toiletry bag.

Excellent
This is a nice affordable hair oil that leaves your hair feeling silky and smooth, not greasy. *Only the smallest bit of oil is needed and massaged through hair with fingers. It’s recommended to use a small bit while wet and then a small bit again after drying to lock in the oil to your hair. After using for 2 weeks, I could truly tell that my hair was silkier and smoother in general even when not used for the day.If searching for a nice hair oil, I highly recommend. This small bottle typically will last me an entire year with use of 2 times a week. If hair does appear greasy after, your using way too much product. It’s a small bottle but it’s powerful, unlike the store bought L’Oréal hair oil you might be used to.

Great product
Wonderful product. It leaves my hair shiny and bouncy. The only reason I didn’t give it 5 stars is because of the smell. It would be amazing if it were scent free

Well worth the price on Amazon best product I’ve used in quite some time
I love all of this line! I received the shampoo & cond in a sample Birchbox! LOVED it from the moment I tried it. I however didn’t order from Birchbox the price is way to steep for me. But the products speak for themselves. I have loved them all. This one doesn’t smell like the fantastic conditioner but it’s not bad either. Just neutral on smell & it fades quick wit the restore. I use it on my ends before blow dry & I also use the Comb & prep, the smell is not great but after its dried into hair & styling it has gone. Makes my hair so manageable. I have hair extensions in a somewhat non traditional way. They are semi sewn on & clamped in 2-3 inch pieces all over my head crown mid shaft & mid nape. I have had them in the past & most shampoos damage them & I have them redone. This time I used a Bohemian hair & use this exclusive & once a week or 2 use it’s a 10, mainly to just use it up. Then I will be strictly using this! Hydrating No 4 Shampoo, Conditioner, prep & comb with Restore on the ends.Yes it is the original & not a knock off, it comes in the box with the cellophane wrap & is sealed well. Same great results as the samples I received.Hair spray I use the Catwalk work it sessions hair spray but very sparingly! Smell is heavenly! My husband says I smell good thinking its cologne 😉

Works!
Love this stuff.

I got to know this product years ago when I received a sample and I loved it straightaway. My ends look damaged when I use other oils but they look so healthy and my hair looks so strong when I use this one. I think that’s because this oil is more of a “thick” oil compared to others I have tried (“body and hair oil”).I’ve been using it again for a few weeks now and I can see a clear difference. Plus it smells so good !! I will buy it again for sure!
