Olaplex No. 7 Bonding Oil, Concentrated High Shine Oil, Heat Protectant, Visibly Smooths & Softens Hair, Added Color Vibrancy, Up to 72 Hour Frizz Control, For All Hair Types, 1 fl oz

I've had this for almost 2 years now, and overall I love it. I have fine, naturally wavy and somewhat dry, frizzy hair. I've used this both on my natural hair and recently on my highlighted hair. I've tried so many hair products in the past, but most were cheap things from the drugstore, and really didn't do anything for me. Finally, I got a product that is actually worth the extra money. This stuff adds noticeable shine and smoothness without weighing down hair or making it look greasy. You only need a very small amount too. After almost 2 years of frequent use, I still have some left. Also, I am sensitive to fragrance, but it's not overwhelming and actually smells really nice (but, it's definitely there, if you are very sensitive). I actually love that it's so small too, because I can easily travel with it. You could literally even throw it in your purse if you wanted (I'd get nervous with the oil, but, it's never leaked on me so far). Does it completely revamp my hair or get rid of all frizz? No. I feel more like it is helping from the outside than the inside, even though Olaplex presents it as bond strengthening. I'm still waiting for that miracle product to appear that just completely fixes my hair texture. But overall it's a great product and unless I find a better alternative, I plan to repurchase once I run out. Definitely worth the money.

I love this hair serum! I have repurchased it several times for my Type 3 Curly, high-porosity hair over the course of two years, and I am about to buy it again. I wash my hair every several days, putting in 4-5 drops on each side of my head (I have really long, thick hair) after my leave-in conditioner and curl cream, and I can tell a big difference between when I use it and when I don't. It leaves my hair shiny after it air dries, and minimizes frizziness even in my humid Florida climate. It is pricier than a drugstore serum, but I think it's definitely worth it.One travel size bottle lasts me around 5 months, and I imagine a full size would run me up to a year.

This is a super good hair oil, the only one I'll ever find myself using. Do NOT use a ton, this is supposed to be applied lightly. If you have fine or medium hair this will benefit you so much. The oil does not weigh down or dampen your hair, it applies smooth and gives a silky shine. Unlike most hair oils I've tried, this one seems to actually get INSIDE your hair follicle, so its results are very very good. Ik it's pricy but it lasts me a long time and is an essential part of my hair routine to prevent dry dead ends.

I was surprised how little was needed for a great result. I had been using another very expensive, high end product ( similar oil). It just wasn't doing anything for my frizzy, straight hair. This was a new situation for me. So I tried the Olaplex and was pleasantly surprised. It cost less and I needed to use less for a better result. It lasts a couple days between washing in rainy weather. I'm happy.

Aunque parece muy pequeño el frasco, al ser mi cabello de hebra muy fina y medianamente largo, no necesito de muchas gotas para darle un buen acabado de brillo a mi cabello, sea que lo cepille o no.No se siente pegajoso ni grasoso een tu cabello, es el toque final de brillo que tu cabello agradecerá.

Lovely addition to my routine but 3 or 4 drops is definitely not enough for anyone who has a lot of super curly hair. Mine's 3B/C that needs a lot of oil. Olaplex can be added to regular hair oil for an extra boost.

Love this! It really helps control my hair without feeling heavy or greasy and it smells great! I'm usually hesitant to buy products this expensive without trying it first, but took a chance. And I'm in FL which is never good for my hair type - long, thick and highlighted.

I've used it a few times and I also mix it with No 6. I wouldn't say it adds shine but it does help a lot with frizzies and moisture. It's a small bottle but it doesn't take a lot with each use so it lasts a while.
