Can Rosemary Oil Improve Hair Loss?

Reading time -

Hair loss can feel really scary, but there are lots of ways to either slow it down, or stop it completely, even if your hair loss is caused by genetics. Hair is a big part of how we present ourselves to the world, and it's a very visible sign of how healthy we are, so it's worth trying to make sure your hair is doing its job for you. Rosemary oil is one of many treatments that may help!

What is Rosemary Oil?

Rosemary is a shrubby, perennial herb that grows in the Mediterranean region. It has beautiful, needle-like leaves and small white flowers with purple centers. Rosemary is very aromatic, and the leaves are a popular herbal remedy.

Rosemary oil, then, is the essential oil extracted from the rosemary herb. It's a pale, yellow-green liquid with a strong, aromatic fragrance. A lot of people use rosemary in their cooking, but the oil is typically used for aromatherapy and to make cosmetics.

Why is Rosemary Oil Good for Hair Loss?

Rosemary oil contains a variety of antioxidant compounds, including carnosic acid, rosmarinic acid, and cineole. Antioxidants are thought to protect hair follicles from damage by free radicals.

It also contains fatty acids, including linoleic acid and oleic acid. Hair follicles need fatty acids to maintain their health, and there's some evidence that supplements with these fatty acids can improve hair growth.

And finally, rosemary oil contains the terpene D-limonene, which has been shown to promote hair growth in mice.

Does Science Stand Behind Rosemary for Hair Loss?

Some studies have found that rosemary oil stimulates hair growth in mice. The studies focused primarily on the effect of rosemary oil on hair regrowth after chemotherapy, but the results are promising.

This study compared the popular hair loss drug Minoxidil and rosemary oil for a six-month period. The impressive results showed that although rosemary oil caused some itchiness, it showed comparable results.

Other studies have shown that rosemary oil can increase hair shaft diameter, increase the amount of anagen hair follicles, and cause hair regrowth in bald mice.

A study on rosemary oil for androgenic alopecia in men found that rosemary oil significantly improved hair loss after eight weeks of treatment. The men also reported less hair loss during the study period.

So, in essence, science does support the use of rosemary for hair loss. It may not be as effective as some other hair loss treatments, but it's definitely worth a try! Plus, it's a great scent, so you can't really go wrong.

How Can You Use Rosemary for Hair Loss?

Rosemary oil is an essential oil, rather than a flavor oil, so it isn't safe to ingest. You can, however, use it on your scalp and hair.

Applying rosemary oil directly to your scalp can help improve circulation and reduce itchiness. You can use a dropper to put a few drops of rosemary oil on your scalp and rub it in, or you can spread the oil through your hair.

You can find rosemary oil at most health food stores. It's typically only a few dollars. Try combining rosemary oil with other essential oils that have been found to improve hair growth, including lavender oil, cedar wood oil, and sandalwood oil.

Rosemary oil may be an effective alternative to hair loss medications, but it's always best to talk to your doctor before starting a new treatment.

Other Treatments For Hair Loss

If you've been looking for a natural option for hair loss, then rosemary oil could be a good choice. However, it's always a good idea to talk to your doctor before using a new treatment, just to make sure it's safe for you.

Minoxidil (Rogaine): This is a very popular treatment for hair loss, and it is effective for some people. It was the active ingredient in the study mentioned above, and it is widely prescribed by dermatologists. However, it has a lot of side effects, including itchy scalp, dry hair, and hair growth in other areas.

Hair transplant: This is a surgical procedure for hair loss in which small plugs of hair-bearing scalp tissue are removed and transplanted to bald areas. It's expensive, it's painful, and recovery can be a long process.

Finasteride (Propecia): This is a popular drug for hair loss that blocks the production of the hormone dihydrotestosterone (DHT). Finasteride is prescription only, but you can get it through Phoenix Health, a telehealth platform only for men. Finasteride can have side effects like decreased libido, erectile dysfunction, and it can also cause birth defects or early puberty in children.

Rogaine and Finasteride are all FDA-approved. If you're looking for a more natural approach to hair loss, then rosemary oil might be a good option for you. But don't make any changes to your treatment plan without talking to your doctor first.
