This Slightly Terrifying New Service Shows You Exactly How Damaged Your Hair Is

Amanda Montell

I colored my hair for the first time when I was 17 years old, and I have never looked back. For almost five years, I tortured it with box dye. Now that I know a little better, I allow a very talented Los Angeles colorist to torture it. (Love you, Matt.) Oh, and I heat-style it a good three times a week.

Intellectually, I understand that bleaching the living daylights out of my hair and then straightening it is not healthy. And aesthetically, I can see that my hair isn’t exactly as shiny as, say, Selena Gomez’s hair or one of Kylie Jenner’s wigs. But I’ve developed a sense of denial strong enough to repress all that. What can I say? I like being blond.

But I’m still sane enough to say yes whenever the opportunity for a reparative hair treatment comes along. So when I heard about Kérastase’s new Fusio-Dose treatment ($30), I was like, Sign me up please thank you. This high-tech, in-salon treatment has a stylist evaluate your specific hair needs to customize a potent repair treatment, which takes effect in just five minutes. It sounded right up my alley.

What I did not realize until I arrived at my appointment at LuxeLab Salon in Santa Monica is that for the process to work, your stylist must snap high-res photographs of your hair fibers to get a close look at just how messed up your mane really is.

By the time my stylist whipped out his iPad, it was too late to back out. I was mere minutes away from having to confront years of hair damage.

The “before” photo above (on the left) was taken a few weeks before my Fusio-Dose treatment; the “after” photo (on the right) was taken several days later. The treatment definitely seemed to boost my hair’s strength and shine. And, importantly, it also inspired me to ensure that I’m making the best choices for my specific haircare needs on the day-to-day.

Seeing my hair up close and personal reminded me that laughing off my damage benefits no one. I think of the process as a sort of hair intervention—a forced rock bottom so I could face my reality and start getting better.

Since the treatment, I have started paying closer attention to the hair products I use, making sure that they address breakage and shine, specifically. I have also made an effort to heat-style my hair less often and apply heat protectants when I do.

If you’re curious (and/or slightly horrified) to see exactly how damaged your hair is, find a salon that carries Kérastase products, and ask for Fusio-Dose. 

When you see an iPad and start to feel like you’re in a futuristic haircare otherworld, you know you’re in the right place.
