Is Rosemary Just a Kitchen Herb or More?

Rosemary is a well-known fragrant herb when it comes to being used in the kitchen. But the uses of this herb go way beyond the kitchen. Traditional medicine has regarded rosemary highly due to its healing, antimicrobial, and antioxidant properties for centuries now. Rosemary was also used for memory enhancement, wound healing, and promoting hair health by the ancient Egyptians, Greeks, and Romans. Modern-day people have also recognized the benefits of rosemary outside the kitchen, and it is now making waves in the wellness industry.

Does Rosemary Oil Grow Hair?

Now that it’s been established that rosemary has many uses beyond the kitchen, the million-dollar question still remains! Does rosemary oil grow hair? Scientific research and beauty influencers (whichever you might trust more) say yes! Following are the ways in which it works:

Improves Scalp Circulation: Rosemary increases blood circulation to the scalp. This ensures that hair follicles get the nutrients that they require for hair growth.
Prevents Damage to the Hair Follicle: Rosemary being rich in antioxidants helps to protect hair follicles from the damage caused by oxidative stress.
Blocks DHT: DHT, or dihydrotestosterone, is a hormone linked to hair loss. Some studies show that rosemary oil helps to reduce the effects of DHT and lessen hair thinning.
Properties of Rosemary Oil: Rosemary oil also helps to combat dandruff, itchiness, and other scalp infections. This keeps the scalp clear, which leads to better and stronger hair growth.
Prolongs the Hair Growth Phase: Research indicates that rosemary oil lengthens the active growth phase of your hair, which leads to stronger and thicker hair.

If you, for some reason, aren’t a huge fan of rosemary oil, here are some other ways you can incorporate rosemary into your haircare for effective results:

Rosemary Shampoo and Conditioner:

Rosemary-infused shampoos and conditioners help to cleanse the scalp and hydrate it. They are often combined with other ingredients like biotin, caffeine, etc., which help to enhance the effects and reduce breakage.

Rosemary Hair Serum:

Rosemary-infused lightweight hair serums are readily available in the market which can be directly applied to the scalp. They often include peptides, which further promote stronger hair growth.

Rosemary Hair Mask:

Use a hair mask with rosemary and other botanical extracts once a week to deeply condition your scalp. This would help to repair damaged hair and strengthen roots.

Rosemary Scalp Spray or Tonic:

You can also opt for a leave-in treatment that keeps the scalp healthy without making it too greasy. Sprays or tonics like these usually include aloe vera and niacinamide in addition to rosemary to support scalp health.

Research-Backed Evidence Regarding the Effectiveness of Rosemary Oil

Hair loss is often surrounded by misconceptions, such as the belief that wearing hats or frequent hair washing causes hair thinning. In reality, factors like genetics, stress, nutritional deficiencies, hormonal imbalances, and medical conditions (e.g., thyroid disease) play significant roles. While treatments like minoxidil are proven to maintain or regrow hair, discontinuing their use results only in the loss of hair sustained by the treatment, not accelerated hair loss. Emerging natural remedies, notably rosemary oil, have shown promise; studies suggest it may be as effective as 2% minoxidil in stimulating hair growth.
