Customers have been raving about the product, with many saying it has become a staple for them.

"This Olaplex Nº.7 Bonding Oil is truly a revolutionary product that has become an absolute staple for repairing damage and achieving that coveted, salon-level shine," one said.

"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 it works out as good value," said another.

"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," another added.

Another shared, "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."
