Rosemary Oil for Male Pattern Baldness (Science)

As per American Hair Loss Association, Male pattern baldness affects 95% of men.

There have been several scientific studies on Rosemary Oil for Male Pattern Baldness and found it to be incredibly effective and even aids in hair growth.

What is Male Pattern Baldness

Male pattern baldness (Androgenetic alopecia) is a loss of hair on the scalp that is caused by androgens. It occurs as a man’s hormone levels fluctuate throughout his life, but notably in his later years.

It is estimated that 50 million males in the United States are affected, and that half of all men will be affected by the time they reach 50.

Below is the data from the American Hair Loss Association:

  • By age 21, approximately 25% men with hereditary male pattern baldness start losing hair.
  • By age 35, approximately 66% men experiences different levels of hair loss.
  • By age 50, approximately 85% men experiences significant hair loss and thinning hair.

The Science behind Rosemary Oil for Male Pattern Baldness

In addition to DHT inhibiting, rosemary promotes hair regeneration and thickening as well as volume. For hair regeneration, it is regarded as one of the finest essential oils.

DHT (dihydrotestosterone) levels in hair follicles are reduced by rosemary oil, preventing androgenetic hair loss. It accomplishes this by preventing DHT from attaching to hormone receptors.

Rosemary Oil inhibits 5-alpha-reductase activity by up to 94.6 percent. Rosemary extract inhibits the conversion of testosterone to dihydrotestosterone by blocking the enzyme 5-alpha-reductase in hair follicles.

In addition to strengthening hair, rosemary oil helps against hair loss by preventing breaking. Aside from relieving itching, its anti-inflammatory qualities can also help prevent dandruff. In the same way as any other oil, rosemary increases the general smoothness and luster of your hair.

Scientific Researches on Rosemary Oil for Male Pattern Baldness

Study 1: According to some scientific research, Carnosic acid found in rosemary rejuvenated nerves in the scalp and aided in restoring hair growth.

Study 2: In research comparing rosemary oil with minoxidil for its ability to promote hair growth in patients with androgenetic alopecia, rosemary was shown to be just as effective. As a result, it has been proven to be effective on both men and women.

As a result of the presence of 5-alpha reductase inhibitors, rosemary is effective in reducing the production of DHT. In certain men and women, the androgen hormone dihydrotestosterone causes hair follicles to stop producing.

Rosemary essential oil was shown to have the same effectiveness as minoxidil. During the procedure, it was more effective than minoxidil at alleviating the itchy scalp adverse effect.

Although rosemary extract or essential oil promotes hair growth, scientists are still not clear on how it worked and the particular mechanisms are yet unknown. But it’s one of the most promising substances for fighting hair loss, so it’s definitely worth a shot.

Study 3: According to another study, essential oils, such as rosemary oil and peppermint oil, can reduce hair loss and promote hair growth. Researchers have already discovered that rosemary oils moisturize and soothe the scalp, which can contribute to the growth of beautiful, healthy hair.

Study 4 and 5: Rosemary has been linked to hair growth in two additional studies conducted in the years 2010 and 2011. People with alopecia who took rosemary oil had a high success rate in regrowing their hair, according to the study’s findings.

Study 6: rosemary oil can enhance the condition of people with alopecia areata according to research released in 1998.

Rosemary oil may be beneficial for those with alopecia areata. Although alopecia areata is an autoimmune condition, rosemary oil appears to reduce hair loss in people who suffer from it.

Despite the lack of scientific proof, rosemary oil may also help other hair loss treatments work better.

Study 7: In a 2016 study using mice and rosemary oil, improved blood circulation on the scalp and delivered nutrients and oxygen required to stimulate hair growth.

How to apply Rosemary oil for Male Pattern Baldness

You may use rosemary essential oil in a number of different ways to help thicken and repair your hair. To begin, try one or two of these treatments once or twice a week. Utilize them more frequently as wanted or when you feel comfortable doing so.

Mix Rosemary oil with a Conditioner or Shampoo

Add a few drops of rosemary essential oil to your shampoo or conditioner. Your hair lotion and cream can also be mixed together if necessary.

Keep it basic and don’t overdo it, if you can. Rule of thumb: 5 drops per 1oz. Use the product as usual. Two or three drops of rosemary essential oil can be added to any hair product that you use on a daily basis.

Apply Rosemary oil Directly on your Scalp

After a bath or shower, rub 5 drops of rosemary essential oil into your scalp. Mixing with a carrier oil like jojoba or coconut is always advisable.

It’s not necessary to rinse the oil afterward. However, if you decide to rinse, let the oil rest on your scalp for at least five to ten minutes before doing that.

Applying rosemary oil to your hair can provide a number of benefits, but if done improperly, it may cause more harm than good. To know more check this article on How to Scientifically Apply Rosemary Oil on Hair

Things to know before using Rosemary oil

Use in moderation: Do not apply too much product to your scalp. A small percentage of people have complained that rosemary essential oil causes irritation. However, it poses no health risks. Avoid skin sensitivity by diluting oils before applying them.

Look for allergy: Before using rosemary oil, make sure you’re not allergic to it. Consider testing the lotion on a tiny piece of your hand before putting it on your scalp.

Greasy or Thin hair: Add oil to your hair care routine with caution if your hair is thin or prone to greasiness. If you’re worried about weighing down your hair, try rinsing it out instead.

Be Cautious: Be careful not to get any essential oils in your eyes or nose. If by mistake if it happens, rinse your eyes with cold water as soon as possible.

Avoid if you are pregnant or breastfeeding: Pregnant or nursing women should avoid using rosemary essential oils because there is not enough information available. The essential oil for hair loss can be used topically, but be cautious as its effects are not yet fully understood.


Rosemary isn’t simply a flavor enhancer for omelet or pizza, it’s also a natural healer. In order to grow your hair without irritating your scalp, rosemary essential oil may be the answer.

For centuries, people have relied on rosemary to stimulate hair growth. The use of rosemary essential oil may have the same effect on you as well.

Its ability to lower dihydrotestosterone levels in hair follicles makes rosemary a popular herb for treating hair loss.

Rosemary oil research is still in its infancy, so it’s impossible to know if it will work for everyone. Although certain hair growth drugs might have adverse effects, this natural treatment may be less harmful and less likely to do so.

A combination of scientific evidence and my own personal experience clearly suggests that the essential oil does protect against hair loss, particularly that associated with male or female pattern baldness. Even alopecia may benefit from it.

Speak to your doctor or dermatologist if you’re worried about turning bald. Depending on your needs, they can work with you to determine the best course of action.
