Summer hit a high point when colorist Tracey Cunningham gave my locks her sun-kissed touch. Even better? How healthy they felt in their post-processed state. That’s because of the hair-strengthening, salon-only treatment called Olaplex. Kim Kardashian is said to be a fan, but I saw the results for myself. Now, I use it as an excuse to visit my stylist, Amanda Scott at Serge Normant at John Frieda, more often. My mane is better for it.
