Nº. 7 Bonding Oil: High Shine | Heat Protectant, Visibly Smooths & Softens Hair, Added Color Vibrancy, Up to 72 Hour Frizz Control | For Coily, Curly, Straight, and Wavy, 30 mL / 1.0 Fl Oz

I’m have straight, thin, fine hair. It seriously gets weighed down even by hair spray, so when I tell you that this product is good for fine hair I mean it. It smells amazing, is lightweight (I use 1-2 drops, 3 drops gets too heavy for me) and transformed my hair from dull, stringy, and slightly frizzy to smooth and sleek. It makes my hair look thicker because it stops my hair from getting stringy which I love. Highly recommend

My #1 go to hair oil. It’s super easy to use and it makes sure you don’t get too much. It’s not sticky but it does leave a slightly greasy feeling in your hands after, it doesn’t however make your hair look greasy if you don’t use too much. It’s amazing quality and super effective at taking frizz and making your hair look and feel soft. I would recommend this product to literally anyone.

This oil has literally become essential in my routine. Olaplex No. 7 leaves my hair with a gorgeous, salon-quality shine, but without feeling heavy. I only use two drops, and it's enough to make my hair look more polished and frizz-free.

I’ve been using Olaplex No. 7 Bonding Oil for about 8 years now, and it is truly amazing—especially as a heat protectant. I blow-dry my hair 3–5 times a week, and thanks to this oil, my hair stays healthy, smooth, and strong. Every time I go to the hair salon, my hairstylist compliments me on how healthy my hair looks, which says a lot considering how often I use heat. I have no split ends, and my hair always feels soft and shiny without being greasy. A little goes a long way, and it’s been a staple in my hair routine for years. I honestly can’t imagine styling my hair without it. Highly recommend!

If you have dry, damaged hair or it was FRIED by an inexperienced hairdresser, this oil will help get it back to a soft, non-frizzy, not so damaged look. I have VERY baby fine blonde hair and recently went to the salon to switch things up. I asked for Elsa Ice Blonde and ended up with fried dishwater blonde. I had to chop a bunch of my hair off but not as much as I thought I would because the Olaplex No. 7 Bonding Oil help saved a decent amount of length. This oil is super lightweight and doesn’t weigh down or make your hair look greasy.

I really like this oil! It is not too heavy and a little really does go a long way. My hair seems to soak it right up and my strands look shiny. I'm hoping that it makes my hair healthier. So far, with repeated use, it does look like my hair is becoming more manageable. I think it is stronger as well. I would recommend it!

Since I moved to the USA, my hair has been suffering from dryness due to the limestone in the water here. I've tried humidifying it with grape oil, olive oil, and various types of leave-in conditioners, but nothing has truly worked. This oil, however, was an exceptional surprise. It not only restored the shine my hair had when I lived in Brazil, but it also made my hair look healthy, smooth, straighter, softer, and beautiful. The bottle is smaller than I expected for the price, but I only need three drops per use, so I'm waiting to see how long it lasts. Nevertheless, given its effectiveness so far, I believe it's more than worth the investment. It’s literally the only thing that has worked for me in the last three years of searching. The liquid is easy to spread, and my hair absorbs it quickly without feeling sticky at all. I'm hoping the bottle lasts as long as the effects do on my hair.

I absolutely love this product for my hair. My hairdresser recommended it for me. It makes my hair so soft without the greasy look. It is expensive but the bottle will last you for a very long. I love how this makes my hair feel…Great Product
