Nécessaire’s Rosemary Serum Is Responsible for My Crazy Summer Hair Growth

To know me is to know I’ve been on a hair redemption journey for four years now. After losing nearly half my thickness due to a combination of COVID-19, a GLP-1, and hormonal changes, I’ve been determined to get my density back and make my existing hair grow faster. My hair growth routine knows no bounds: my blood has been injected back into my scalp to stimulate the follicles (a process known as PRP), I’ve tried scalp microdermabrasion, started getting monthly trims, and completely overhauled my at-home routine.

My shower is similarly stocked: there are hair growth shampoos, volumizing conditioners, and an exorbitant number of scalp scrubs. (Hair isn’t going to grow on an irritated scalp!) But one of the most impactful additions I’ve made to my hair growth routine happens right out of the shower—with Nécessaire’s new Rosemary Serum, which is available today, August 5. I’ve been secretly testing it out for a few weeks, and my hair feels stronger and thicker already. My full, honest review, ahead.
