How to Fix Brassy Hair and Highlights

Then I was referred to Rita Hazan, the woman who saved my life. (I might have a slight flair for the dramatic, but bear with me.) She promised to turn my two-toned brassy highlights into a sun-kissed blond, and when Beyoncé trusts someone to color her hair, so do you. She started the process with a first round of highlights to lift the color since the problem with my last two treatments was that the lightener wasn't left on long enough to take my dark roots into a light blond. She used a teasing technique to highlight my entire head and left me in foils for 10 or so minutes. After washing out the color and drying my hair, she applied more lightener using the standard weaving-comb technique to correct the color to be closer to my roots. After a few more minutes of foil, I had a new head of hair—and new bouncy layers, because why not?

After spending the day in Hazan's chair, I learned that I'd been far too nonchalant about being a blond. I could have easily prevented my disaster of a highlight job by simply following some basic guidelines: (1) Do your research (e.g., look up colorists' portfolios on Instagram to see who does a great job at the color you want), and (2) get a consultation. I'm embarrassed to admit I did neither—especially considering my breathing-to-Insta-stalking ratio. Below, here are the other tips I picked up on how to fix brassy hair.

1. Ask for a corrective color—the right way.

If you make my mistake and don't do your research, there's a right way and a wrong way to ask for a corrective color. “If you don't like your color, just say you don't like it,” advises Hazan. “If you start crying or get aggressive, it makes the colorist not really want to help. It's best if you simply state, ‘I wanted it a little lighter—would you mind making it a little lighter?’ If you come at a person in an aggressive or dramatic way, you lose the sense of wanting to fix your hair and get caught up in emotion.” Seems pretty obvious, right? Not if you're like me and get riled up in the moment, but Hazan pointed out that I could have told the manager of the salon if I didn't feel comfortable telling my colorist.

2. Don’t try to fix it yourself, no matter how tempting. 

I'm the clear case study of what happens when you feel too awkward to tell someone you don't like their work, but I am so thankful I didn't try to correct the color myself. There's no doubt in my mind I would have either lost all my hair or turned it green if I had attempted Pinterest hacks or used drugstore dye. Purple shampoo and purple glosses don't count since they're not so much corrective as they are preventive. In fact, Hazan is super pro-gloss, bringing us to…

3. Do try a gloss.

“The system that everyone is missing from their routine is glossing,” Hazan told me. “Your hair is going to fade and get dull, so you have to do something in between at home to keep it shiny and vibrant.” She suggests using her Breaking Brass Gloss two or three times a week to prevent your hair from turning yellow or orange. (It comes in five colors, so you can pick whatever makes the most sense for your hair.) Additionally, I've been using DryBar Blonde Ale and Amika Bust Your Brass Cool Blonde Shampoo to keep my color fresh and bright to wild success.

4. Deep-condition weekly. 

Hazan's Weekly Remedy is another treatment she recommends using once or twice a week, especially if you're blonde. “It's one of my favorite products. I manipulated conditioner to do what I want it to do,” she says. “The first step has all of these great ingredients and a high pH balance, so it opens the cuticle, and the second step has a lower pH balance, so it locks in all of those great ingredients.” I honestly couldn't believe it was my hair after using her product only once—especially after all the damage I'd accumulated. Also a goodie: Hazan's Triple Threat Split End Remedy. It basically glues up your split ends to keep your long hair healthy. Dynamic duo? I think so.

Obviously, products don't come cheap, but having to redo color and throw down for corrective treatments ends up being even more costly. Now I'm committing to a maintenance routine of touch-ups every three to four months with a colorist I trust (ahem, Rita, my saving grace). It sucks I spent my trip to Mexico (and my 24th birthday) with a brassy hairline. But at least it led me here.
