No.7 Bonding Oil™ - Haaröl

Not a bad product, just not the right fit for me

I wanted to love the Olaplex Bonding Oil because I know it works well for so many people, and to be fair, it did work decently it added some shine and smoothed flyaways. But for me, it just didn’t deliver the kind of hydration or transformation I was hoping for. I think the issue might be my hair’s porosity—it didn’t seem to absorb the oil well, and the results felt pretty surface-level. It’s not a bad product, just not the right match for my hair type. Might work better for those with different texture or porosity.

Great for fine hair!

Love this oil for fine hair! It’s lightweight and is absorbed into their hair very easily. Also provides a nice shine. Only wish you got more in the bottle.

Not for me

I have very thin dry hair, and I really struggle with frizz. I’ve been trying to create a good hair routine so thought I’d give this a go, personally for me I felt that it made my hair more frizzy and I didn’t really like the texture of my hair after I used this. I have wavy hair and I feel like this didn’t give the shine or moisture that I was looking for. However I have friends that love this product so I guess it depends!

A Game-Changer for Frizz and Heat Protection

Olaplex No. 7 is truly a holy grail hair product. I’ve tried a lot of oils and serums, but nothing quite compares to this one. It’s incredibly lightweight, yet somehow delivers intense shine, smoothness, and protection all at once. Just a few drops go a long way, and it never leaves my hair feeling greasy or weighed down. The frizz control is amazing — even on humid days, my hair stays sleek and manageable. Plus, it has built-in heat protection up to 450°F, which gives me peace of mind every time I blow dry or style. What I love most is that it actually strengthens my hair while making it look polished and healthy. It’s the perfect finishing touch for any style, and it works beautifully on damp or dry hair. A little bottle with big results — I’ll never go without it.

Not worth the price!! Very overpriced for what it offers. You use it once and already somehow the bottle is halfway done.

oily, doesn't absorb, doesn't repair

This just sits right on top of my hair and looks oily, even though I use super light amounts. There has been no short- or long-term improvement in my hair's health or appearance. It's certain not bonding anything. I spent the extra money to get the K18 Molecular Repair Hair Oil and it is AMAZING. I will never be going back to Olaplex.

Best hair oil imo. Have repurchased this so many times. Leaves a beautiful lightweight shine and smells amazing!

Brought my hair back from the dead

I am very picky with hair products and was expecting to hate this, but after frying my hair with bleach and then finishing it off by abusing a protein/collagen mask and it was looking like the end of some fibre optic cables, I was desperate. I’d never had so much breakage and volume loss, and it was like my hair stands grew tiny hands and would grab on to my wet hair brush and rip out of my head. This mask helped bring it back to life, along with the no.8, no.3, & no.5L, I’ve repeat purchased them all and I’ll do it again.

A must have

After using this product for over 2 months, i can recommend this product to you too. It’s so Light weight, non greasy and gives shine. It’s an amazing oil

love

have been using for half a year and im still in my first bottle, makes my hair instantly shinnier and smoother

It’s lightweight, non-greasy, and works wonders on frizz. My hair feels smoother, shinier, and healthier after just a few drops. It also helps protect against heat damage, which is a huge bonus. A little goes a long way, so the bottle lasts a long time. Definitely worth it if you struggle with frizz or dryness!

Nice product!

I recently got a sample size of this after purchasing something. I've only used it three times but I feel like my hair is softer and way less frizzy/dry!
