The benefits of rosemary oil for hair growth: Can it really help thinning hair?

Neal’s Yard Remedies Rosemary and Cedarwood Hair Treatment is a luxurious, deeply nourishing formula designed to restore vitality and shine to tired, lacklustre hair. Infused with natural ingredients like rosemary and cedarwood, this treatment conditions and revitalises, leaving hair soft, silky, and full of life.

Ideal for mature hair that may have lost its natural lustre, it helps balance scalp health, reduce dryness, and promote strength—all without weighing hair down.

Senior Writer Hannah Carroll has been using this product for months and considers it an essential step in her haircare routine. After experiencing hair thinning and breakage due to excessive chemical treatments, she turned to natural products to restore her hair’s health.

"I love this product—it melts effortlessly in your hands and feels wonderful when applied. However, a little goes a long way, so apply sparingly. I like to use it as an overnight treatment, covering my hair with a shower cap to allow the product to deeply nourish my roots and scalp. At first, I was apprehensive about how greasy my hair looked, but to my delight, it washed out beautifully. After just one use, my hair felt noticeably softer and looked healthier," she says.

Mielle Rosemary Mint Scalp & Hair Strengthening Oil is a powerhouse treatment designed to nourish the scalp and support healthy hair growth.

One of its standout ingredients is mint—specifically peppermint oil—which offers a refreshing, cooling effect that soothes irritation and itching. This makes it especially beneficial for those with dry or sensitive scalps. Mint also boosts blood circulation, ensuring hair follicles get the oxygen and nutrients they need to thrive.

Our product tester, Ella Croft, has been using this oil weekly for two years—and impressively, she’s only gone through two bottles! She shares, “I first started using it to help with hair loss after seeing it all over social media. I massage it into my scalp and leave it for a couple of hours before washing my hair. You can really feel the tingly sensation from the rosemary and mint—it’s meant to stimulate growth, and I believe it works! After just a few weeks, I noticed loads of baby hairs coming through. I’d definitely recommend it. Just be prepared to give your scalp a thorough wash afterward to remove the oil. Also, I personally love the strong scent, but it might be a bit intense for some.”

This Rosemary Hair Oil is expertly crafted to promote hair growth and nourish your scalp with its unique blend of Black Seed, Sweet Almond, and Sunflower oils. We love this product because it's derived from 100% natural Rosemary Leaf Oil.

Black Seed oil is a natural moisturiser. It is rich in fatty acids like linoleic acid, which can help retain moisture and support the skin. The oil is also rich in natural anti-oxidants, which contribute to the neutralisation of free radicals. This can promote the renewal of skin cells, enhancing overall skin texture, tone, and appearance.

Sunflower Oil is also a natural moisturise. It can help revive dull, dry or frizzy hair.  It will promote a healthy scalp, offering hydration and nourishment. It is also rich in Vitamin E and Omega 9, all beneficial to skin and hair health. 

Sweet Almond oil encourages softer, smoother hair, making it silky to the touch. High Levels of Vitamin E provide an antioxidant effect, making hair less prone to environmental stresses.

Put all three together, and you have a potent combination that is wonderful for all hair types.

Yours Senior Writer Hannah Carroll loves this product; she says, "As a woman with afro hair, I often wear protective styles or use keratin or straightening treatments, which can be tough on my hair. I’ve been using Tisserand Aromatherapy Natural Pure Rosemary Essential Oil, and it’s become a must-have in my routine to restore hydration. While I haven't noticed huge hair growth yet, I love how it makes my hair look and feel healthier. The oil adds a beautiful shine and leaves my hair silky while also helping to combat the dryness caused by styling.

"After washing and blow-drying, I apply it to lock in moisture and restore the shine that’s often lost during the drying process. The scent is absolutely incredible, giving my hair a refreshing boost. I also love how easy the pump dispenser is to use—no mess and just the right amount every time. Overall, it’s a fantastic product for keeping my hair nourished and vibrant, and I highly recommend it to anyone looking to improve their hair’s health and manageability."

We all know the struggle of using hair oil without making a greasy mess or wasting product. This rosemary oil is perfect for beginners or anyone like us who might not always apply products as gracefully as we'd like.

Its easy-to-use applicator ensures smooth, even coverage, so you can nourish every strand and soothe your scalp with zero hassle. Just apply it and leave it in for a few hours or overnight, and you’ll have soft, shiny hair in no time. Plus, it’s made with care in the UK and 100 per cent cruelty-free, which we absolutely love!
