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.

I’ve been using Olaplex for years and one bottle of this oil lasts me a year. A little goes a long way. I apply it on damp hair and on dry hair and my hair never looks oily or weighted down. Such a beautiful oil. I have tried many other ones and nope, this one is the best. It’s such a good value because it lasts forever. Don’t waste your time looking for a cheap hair oil, try this one and I’m sure you will like it! Your hair will be strong, shiny and frizz free.

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.

This oil is my holy grail. It saved my hair from being frizzy and dead (with lots of split ends) and it lasts literally forever. I am still on my first little bottle and it has been 2 years. SO worth the money and I cannot live without it. Do not use it on wet hair — it doesn’t work. Only use it on dry hair. I especially use it after blow drying and it works wonders!

I was looking for a good leave-in product, and this missed the mark for me. My hair wasn’t as managed as I was hoping. It is, however, great for smoothing flyaways when making a bun/ponytail. My hair doesn’t look/feel greasy after using.

I'm so happy with this hair product, it's been amazing! I have very long hair, and I don't want it to get frizzy in humidity. This has worked beautifully to protect my ends, keeps frizziness down, but also does not weigh my hair down or come off as oily at all. I absolutely love this, I'm so happy I found it!

Love this hair oil. It has a nice subtle scent to it. Really made my hair super shiny and would always get compliments with my hair. The only downside is that it’s a little bit expensive for a small bottle. The quality is good and effective but i don’t know if I’m gonna repurchase.
