If you are seeking to transform dry, damaged hair into soft, smooth, and resilient tresses, this oil is a must-buy. -----

I’ve been using the Olaplex No. 7 Bonding Oil on my curly hair for a few weeks now, and honestly, I’m really impressed. From the moment you pump it out, it smells fresh and light — not too heavy or perfumed — which makes it feel really refreshing every time you apply it. For my curls, this oil has been a game changer. A tiny bit goes a long way: it smooths frizz, adds shine, and really helps define my curls without weighing them down or making them greasy. I love how soft and manageable my hair feels afterwards, even on days when it’s been exposed to humidity or heat styling. It leaves my curls feeling nourished and healthy rather than sticky or oily, which is exactly what I was hoping for. Overall, it’s become a staple in my curly-hair routine — gentle, effective, and definitely worth trying if you want smooth, shiny curls with a light, refreshing feel.

I use a few drops of this on my hair every day, focusing on the top layer, which can become dry and frizzy. It's so spreadable, I rub a few drops between my hands and a really small amount is enough for all my hair because it spreads so well. It never feels heavy or greasy on my hair, and it really improves the condition and makes it look great. Quite expensive but one bottle lasts 6 months, so works out good value.

This did make a difference to my frizzy, dry, fine wavy hair. I blow dry twice per week, and noticed an immediate difference. Nothing startling, just a good deal less dryness. I applied both before drying and after (2 drops), and did notice more smoothness, which is saying something, as my hair has been horrific for some time. I do think that I had sufficient results from using a leave in conditioner (cheap toni & guy), but the two combined were amazing. I do not use any other Olaplex products, and did not see good results after salon treatment, but this is pretty decent.

The Olaplex No. 7 Bonding Oil is an absolute revelation, and I can confidently say it's a non-negotiable step in my hair care routine now! This little 30ml bottle is truly liquid gold for my hair. I'm constantly styling with heat, and finding a product that offers serious heat protection (up to 450°F/232°C!) while also improving the health of my hair has been a challenge. Olaplex No. 7 does exactly that. I apply a few drops to damp hair before blow-drying or styling, and my hair feels genuinely protected, not just coated. The high shine it delivers is incredible – my hair looks so much healthier and more vibrant without feeling greasy or weighed down. It really makes my color pop, which is a huge bonus for my dyed hair, helping to maintain that fresh-from-the-salon look. And the frizz control? Phenomenal! Even in humid conditions, my hair stays smooth and sleek for days. The claim of "up to 72 hour frizz control" is no exaggeration for me. My hair feels incredibly smooth and soft to the touch, and it's much easier to manage. A little goes a very long way with this concentrated oil, so despite the small bottle, it lasts a surprisingly long time. The innovative dispenser makes it easy to get just the right amount without waste. Whether you have fine, thick, curly, straight, or color-treated hair, this oil is a universal wonder. It truly transforms the look and feel of your hair, delivering visible results. If you're looking for a multi-tasking hair oil that offers shine, softness, frizz control, and excellent heat protection, the Olaplex No. 7 Bonding Oil is an absolute must-buy!

Amazing hair oil that makes my hair look and feel amazing. I use this before I airwrap my hair, and it makes my blow dry last so much longer.

I wasn't sure if I should believe the hype around this, but ordered it anyway. I'm very glad I did. I'm 67 and since the menopause my hair has become very dry, it frizzes and is unmanageable. I used this bonding oil for the first time last night and the result is amazing. After air-drying and straightening, my hair is shinier and softer than it's been for decades. It's pleasant and easy to use. I will definitely continue to buy it.

It’s tiny, and with thick hair I had to use loads of the product unlike with other hair oils.
