Rosemary Extract Reduces Dihydrotestosterone (DHT) in Hair Follicles

The Health and Beauty Benefits of Rosemary Extract

Rosemary extract has long been known for its health and beauty benefits. The oil extracted from rosemary leaves is known to be capable of enhancing memory and increasing alertness, potentially can be beneficial for the treatment of Alzheimer's disease. In addition to its medicinal and culinary uses, rosemary oil is often used to revitalise hair follicles and maximise hair growth.

5-alpha-reductase and Dihydrotestosterone

5-alpha-reductase is the enzyme that converts testosterone to dihydrotestosterone. Both in men and women, it is estimated that up to 10% of testosterone in the body get converted to dihydrotestosterone.

In some individuals, dihydrotestosterone gradually reduces the blood flow to hair follicles. This process often takes place over several years until some of the hair follicles could no longer grow hair.

It is not uncommon for men to have suffered from hair loss since in their early twenties. However, women do not usually suffer from hair loss until in their forties. Androgenetic hair loss is the most common hair loss in both men and women. Left untreated, it can cause permanent, irreversible baldness.


Rosemary Extract inhibits 5-alpha-reductase

A study published in the Phytotherapy Research showed that Rosemary extract inhibited the activity of 5-alpha-reductase by up to 94.6%.

By inhibiting the action of enzyme 5-alpha-reductase in hair follicles, rosemary extract reduces the conversion of testosterone to dihydrotestosterone. Lower levels of dihydrotestosterone (DHT) in hair follicles helps prevent androgenetic hair loss.

Rosemary in Androgenetic Hair Loss Formulas

Rosemary is one of my favourite ingredients for hair loss formulas. For best results, I combine rosemary oil with other hair growth stimulating ingredients like caffeine, niacinamide, menthol, cedarwood and thyme essential oil.



Rosemary oil is one of the ingredients in both Hair Growth Serum and Scalp Stimulator. I believe that using botanical extracts like rosemary oil, caffeine and menthol to reduce hair loss and promote hair growth is better than using conventional medicines like minoxidil and finasteride. Botanical extracts often contain phytochemicals that help improve the overall health condition. It may take longer to see the initial results, but with regular daily use, the long-term results may be better. Nevertheless, like with every ingredients, be it synthetic or natural, results are vary among individuals.
