 Rosemary oil has been one of the top hair trends this year. Like myself, so many people are prioritising their hair health in 2024, so it's no surprise that the Mielle Rosemary Mint & Scalp Hair Oil is still a hit. 

Hundreds of TikTokers have shared videos of their hair oiling routines using the bestselling rosemary oil, raving about the product for improving hair growth. 

I bleach my hair and wear extensions, and in the last year, I've noticed thinning around my scalp area. I was looking for a hair care product to help my hair feel fuller while still being affordable, so the Mielle oil seemed like a no-brainer. I've now been using the hair oil regularly for six months, so scroll on to read my honest thoughts...

The viral hair growth oil often causes mass sell-outs on the Amazon site. Thankfully, the beauty buy has just been restocked – and it's on sale. 

Retailing at £9.99/ $9.50 on Amazon, the rosemary oil is described as being designed for "daily use, scalp treatment, and split-end care". The oil comes with different instructions depending on what you're looking to work on. For scalp care, Mielle recommends sectioning out the hair, applying a small amount to each section massaging in using your hands or a brush, combing the product through to the ends, and leaving in.

As improving hair growth is my main concern, I followed this method on my hair wash days. Rather than leaving the product in, I washed it out after about an hour. I think the oil could be a great leave-in treatment if you have thicker hair, but if you have fine hair as I do, I would recommend trying it as a wash-out treatment first to avoid weighing your hair down.

The first thing I noticed about the hair oil is the lovely mint scent that feels so fresh in your hair. I found the applicator super easy to use, as you can apply the oil to your hands or straight to your hair. 

I've been using the oil as a scalp treatment roughly once a week for six months, applying the product all over my scalp with a scalp massager as I find it gives the best coverage. On days when my hair is clean, I've been using the oil on my ends for hydration, and I'm really happy with the results. The oil doesn't make my hair feel greasy, and it gives the same glossy feel as other oils I've used before that have a much higher price tag.

The Mielle oil has received generally positive reviews on Amazon, with several commenting on its fresh scent and how it has improved their hair growth. 

One wrote: "Smells like mint and tea trees. So fresh and clean. Easy to use, my hair growth has doubled since using. It used to take me a year to grow three inches; now, I get my hair trimmed at all my appointments. I bleached my hair, and it became damaged; I credit this with helping it feel soft and healthy again. I will purchase this again."

Another commented: "This is a little gem of a product that has really helped the edges of my hair. This is my third bottle from Amazon as the price is fantastic. The peppermint scent is lovely and not too overpowering and it lasts ages as a little goes a long way!"

Final thoughts on the viral Mielle Hair Oil

I've been consistently using the rosemary hair oil for six months, and I've definitely noticed more hair growth around my scalp, which is where I focus the oil the most. My hair also feels softer from applying the product to my ends, so I'm looking forward to seeing how it will continue to benefit my hair in the long term. As the oil is suitable for all hair types and can be used in several different ways, I would definitely recommend trying the product if you've suffered from hair loss or would like to improve the general health of your hair.
