"I finished one bottle of Olaplex No 7 Bonding Oil, which I use after washing and before I heat style, while I use the cheaper Garnier oil each time before I brush my hair to reduce friction."

"This Olaplex oil, I have been using it so much every day and hardly anything's used, perfect size for travel. I've been using this every day on my hair because I've been washing my hair every day, so I'm frizzy at the moment, but this oil is really, really helping keep it under control, and it's actually a heat protectant. I've enjoyed putting this through my hair at the start of the day before we go in the sun, and then after I wash it, just to try and tame some frizz. It's a really lovely oil."
