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.

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 was surprised how small the bottle was for the price. Luckily I only need to use 3 drops so the bottle will last me a long time. Happy with the product it make my hair feel really soft. It also stops my hair from going frizzy I would recommend.

A little goes a long way. Bit pricey, but actually leaves hair shiny and soft with a lovely smell, so worth the expense.

A little disappointed, no shine on my hair. Has a nice texture, doesn’t make the hair feel greasy.
