I Tried This Rosemary-Infused Hair Duo For 4 Weeks & My Hair Is Healthier Than Ever

In my recent quest to level-up my hair care, all roads led me back to rosemary oil. The scalp-stimulating essential oil has anti-inflammatory and purifying properties, and it’s been clinically shown to promote hair growth1.

Needless to say, when I heard our senior beauty editor rave about Nécessaire’s new Rosemary Shampoo and Conditioner, I immediately swapped out my existing lineup—and I hate to be the bearer of bad news, but this $56 duo is 100% worth the hype. 

A few months ago, I learned scalp care is just as (if not more) important as hair care. Experts say you should treat your scalp like an extension of your face, delivering it nutrients for healthy skin and hydration. 

In a perfect world, I’d have the time and money to create an entire scalp care routine—but I love that Nécessaire’s products are created for both your scalp and your hair. Now I’m checking off two boxes at once, and I’m seeing serious results.

My scalp was a bit inflamed when I started testing this formula, but I now it's nourished and calm.

I’d be remiss not to mention this duo’s subtle rosemary aroma. I love that it’s not too overpowering, but lingers with you after the shower as if you just came from the spa.

These products are more expensive than what you might purchase at your local drugstore, but a little goes a long way (and the quality is way better). You really only need a dime-sized amount, and (if you're anything like me) you’ll be feeling the benefits after just one wash.

I recently spent five days (two washes) away from this shampoo and conditioner, and I actually missed it while I was gone.

The formula delivers each one of the benefits I listed above: Since I started using it four weeks ago, my hair is softer than ever and it looks salon-level glossy every single day.

What’s more, my scalp and my hair both feel healthier. I no longer feel inflammation, buildup, or irritation in my scalp; instead my scalp feels calm and fresh. Plus, my hair actually feels clean.
