Rosmarinus officinalis L. is a medicinal plant with diverse activities including enhancement microcapillary perfusion.
A study has investigated the clinical efficacy of rosemary oil in the treatment of androgenetic alopecia ( AGA ) and compare its effects with Minoxidil 2% [ Regaine ].
Patients with androgenetic alopecia were randomly assigned to rosemary oil ( n = 50 ) or minoxidil 2% ( n = 50 ) for a period of 6 months.
After a baseline visit, patients returned to the clinic for efficacy and safety evaluations every 3 months. A standardized professional microphotographic assessment of each volunteer was taken at the initial interview and after 3 and 6 months of the trial.
No significant change was observed in the mean hair count at the 3-month endpoint, neither in the rosemary nor in the Minoxidil group ( P more than 0.05 ).
In contrast, both groups experienced a significant increase in hair count at the 6-month endpoint compared with the baseline and 3-month endpoint ( P less than 0.05 ).
No significant difference was found between the study groups regarding hair count either at month 3 or month 6 ( more than 0.05 ).
The frequencies of dry hair, greasy hair, and dandruff were not found to be significantly different from baseline at either month 3 or month 6 trial in the groups ( P more than 0.05 ).
The frequency of scalp itching at the 3- and 6-month trial points was significantly higher compared with baseline in both groups ( P less than 0.05 ).
Scalp itching, however, was more frequent in the Minoxidil group at both assessed endpoints ( P less than 0.05 ).
The findings of the present trial provided evidence with respect to the efficacy of rosemary oil in the treatment of androgenetic alopecia. ( Xagena )
