Possible efficacy of Lavender and Tea tree oils in the treatment of young women affected by mild idiopathic hirsutism.

BACKGROUND: Hirsutism is defined as the presence of excessive terminal hair in androgen-dependent areas of a woman's body. Regarding this it has been suggested that Lavender and Tea tree oils may have antiandrogenic activities. AIM: To evaluate therapy based on Lavender and Tea tree oils in women suffering from mild idiopathic hirsutism (IH). SUBJECTS AND METHODS: A prospective, open-label, placebo- controlled, randomized study was performed: women affected by mild IH were randomly assigned to receive oil spray containing Lavender and Tea tree oils (group T) (no. = 12) or placebo (group P) (no. = 12) twice a day for 3 months in areas affected by hirsutism. Evaluation of hirsutism was carried out at baseline and after 3 months by Ferriman-Gallwey score and by measuring hair diameter taken from some body areas. A hematological and hormonal evaluation was carried out at baseline and after 3 months.
RESULTS: No significant variations were found in any of the hormones studied in groups T and P between baseline and after 3 months. A statistically significant decrease of hirsutism total score and of hair diameter was found in group T, while no statistically significant difference in these two parameters was observed in group P; in group T percentual reduction of hair diameter was significantly greater than in group P.
CONCLUSIONS: Lavender and Tea tree oils applied locally on skin could be effective in reducing mild IH; this treatment could represent a safe, economic and practical instrument in the cure of this disease.
