InStyle's editorial guidelines Published on July 17, 2024 @ 04:00AM Photo: Amazon / InStyle I prided myself on the health of my virgin hair my entire life. And then I got bored. I needed a big aesthetic change but I’m afraid of the pain of piercings and can’t make the lifetime commitment of a tattoo. So I settled on a massive hair transformation—I took my dark brown curls to season two Carrie Bradshaw-blonde. It’s been 10 months of repeatedly subjecting my hair to bleaching and chemicals. The process has taken a toll—my hair simply stopped growing. For the first time in my life, I went more than six months without a cut. Something needed to be done so I began using Eva NYC’s now-$13 Mane Magic 10-in-1 Primer Treatment. Of all the options at my disposal, I picked this one because of its 6,000-plus five-star ratings and the titular 10 benefits include frizz reduction, nourishment, strength, hydration, softness, and shine. I also wanted something that I could go through bottles of without obliterating my bank account. At $15, it was an attractive choice—and even more so now that it’s on sale for $13.

Although the instructions say to begin mid-strand, I covered root to tip. When my hair dried it didn’t look like a tumbleweed; the frizz was not gone but was much less severe than it had been for months. My strands looked silkier and felt much softer and noticeably more moisturized. I wasn’t expecting anything long-term, I was just happy to run my fingers through my hair without wincing at its brittleness. Three months later, I was doing my hair and remarked “oh god, I need a haircut.” Then I realized what I had just said and how I hadn't said that in forever. The growth I witnessed was an unadvertised but incredibly welcomed side effect. It ultimately makes sense, since stronger hair means less breakage—which, in turn, means longer strands. It also makes sense given that the formula includes argan and sunflower seed oil. The former is a scalp health-boosting antioxidant, and the latter is rich in vitamin E, which improves scalp circulation potentially leading to growth. I have two bottles of Eva NYC’s now-$13 Mane Magic 10-in-1 Primer Treatment in my bathroom. In this summer weather, I especially can’t be without its frizz-reducing properties. And I simply do not want to be without its growth benefits, either. Scoop up a bottle yourself while it’s $13 during and check out other hair care must-haves below.
