The science behind rosemary oil for hair loss.

There are many causes of hair loss including infections, hormonal shifts, age, genes, treatments among others. Studies have shown that rosemary can reverse some cases of hair loss.

The most common type of hair loss in men and women is known as androgenetic alopecia which is believed to be related to a person’s genes and sex hormones, testosterone.

DHT (dihydrotestosterone) is known to attack follicles leading to permanent hair loss. This problem is more rampant in men because they produce quite an amount of testosterone than women.

A trial published in 2015 studied the effectiveness of rosemary oil on hair loss due to androgenetic alopecia compared to minoxidil which is a conventional treatment. 100 subjects participated in the study. 50 of them used rosemary while the other 50 used minoxidil. After 3 months of the trial, none of the subjects showed any improvements. After 6 months both groups saw significant changes in their hair count. Both rosemary and minoxidil performed well as hair loss remedies with rosemary showing no signs of scalp itchiness as a side effect.

In another study to stimulate hair growth, mice were used as the subjects and their loss was triggered using testosterone. In this study though rosemary leaf extract was used instead of the oil. This stimulated hair growth in the mice.

A research published in 1998, looked at the effect of rosemary oil on people with alopecia areata, an autoimmune disorder that can cause hair loss. The treatment was administered by aromatherapy. A higher percentage of participants 44%, improved with the use of rosemary for 7 months compared to 15% of the participants who received no treatment at all.

A 2016 study shows that rosemary has an effect on the blood circulation in rats. This improved their skin health. If the same is true for humans, then rosemary prevents hair loss by improving the circulation of blood to the scalp hence enhancing hair and scalp health.

There is no evidence showing that rosemary oil can stop hair loss due to chemotherapy.
