It seems like this little glass bottle became a TikTok star overnight. Mielle Organics Rosemary Mint Scalp & Hair Strengthening Oil is a cooling scalp and hair treatment — with more than three million views — that features rosemary oil and studies support that this botanical is the rare ingredient that can help grow hair longer and stronger. As someone who has a hard time with length retention and is always trying to grow my hair, I was excited to try it out. After a few weeks of applying the oil on my scalp while I had braids in, I started to see a difference. My hair feels thicker and healthier. Not to mention I love how moisturized this keeps my scalp and the dropper makes it easy to apply between my braids. The oil has a very herbaceous, almost pepperminty smell (it does contain rosemary after all). I use it religiously, especially after the results I’ve seen so far. It’s a pre-shampoo shampoo treatment, so you massage it onto your scalp, then wash it out, but I like to use it about two to three times a week, adding a few drops and massaging into my scalp — my hair is on the thicker side so I opt to not wash it out.
