There was a time when we were a bit skeptical about hair oils—the last thing we wanted was a greasy, weighed down ’do. These days, however, we can't imagine a haircare routine without it. This strand-saving elixir gives drab, dull hair a coveted movie star shine (plus a whole host of reparative benefits). Our oil-free days are officially over.
Use very sparingly and in small amounts or else your hair will look very greasy4
Love it! I have very very fine, long, color treated hair, so I need a little extra strength/moisture and shine without weighing down my hair any more than usual. I've tried all sorts of serums and glossing creams and stuff in the past with usually average results at best - either I'm not getting the shine results I want or I look like a wet dog, all weighed down with goop. Bought a bottle of this on a whim since I've been such a fan of the other Number 4 products I've sampled, and I'm SO glad I did. This is it.
After a couple of uses, hair is exceptionally shiny and looks healthier than usual. However, my hair is NOT weighed down at all. If anything, it's moving more than usual. And it feels super soft. I'm hoping continued use does improve the health of my hair, but even if not I'd keep using this stuff based on looks alone.
I use just a few drops on the ends of my wet hair and I enjoy the texture and shine that the producr provides. I have really dark, thick, long hair, so most products that I have tried I need to use tons to get the desired effect. This stuff really works with minimal application. Smells great too5
Smells great, leaves my hair looking and feeling healthy, and is extremely potent. The product seems much more expensive than it is selling for and you only need a tiny amount!5
I've been using this religiously for two years now - and have only just finished my second bottle! I have long, fine, straight, color-treated hair and this is a godsend. I use two pumps after I towel dry, and it makes my hair so smooth and silky, protects, the ends, and fights static and frizz. Plus, it smells amazing. My only complaint is the pump. It leaks if you try and travel with it. My solution is to pour a bit in another Birchbox hair oil sample container I received - and good to go!5
I really like this - I try to wash my hair as infrequently as possible, and this is GREAT for my non-washing days to keep my hair smooth, shiny and looking well-conditioned. It smells great too!5
two thumbs up from this dry-haired blondie! Not only did I like the smell of this product, I also liked the appearance that it had once applied throughout my hair. Instead of giving off a thick and greasy look, it shimmered with a healthy glow. A little goes a long way!5
If you have dry hair this is a product you must have. Myself I have very dry hair. All's I have to do is put a small amount in the palm of my hand and apply starting at the roots and my hair is transformed in to this silky smooth hair. And it is hard to find a product that actually sticks to my hair. Like I said I have very dry hair. Definitely must try this one out.5
I have used many hair products, for a long time I had my hair relaxed and colored so it was exposed to lots of chemicals. Recently I stopped relaxing and just using keratin. The point is that besides having used many products I know wich ones don't work in my hair instantly. This product was absolutely wonderful it didn't leave my hair oily not the first time using it and even if I use it everyday, it does not weigh down my hair. Its my favorite I use it on my hair, my daughters and my friends when they ask me to blow dry their hair. Its absolutely wonderful..5
This product makes my hair silky and shiny - no grease or weighed down!! I use it before I curl my hair as a heat protectant as well!4
