    This study investigated the hair growth-promoting effects of Rosmarinus officinalis (rosemary) leaf extract using in vitro and in vivo models. The results demonstrated that the extract and its major component, 12-methoxycarnosic acid, promoted hair growth by inhibiting the activity of 5α-reductase, which is involved in androgenetic alopecia.

    This study investigated the effects of polyphenolic extracts of Rosmarinus officinalis (rosemary) on hair graying and hair growth in mice. The results showed that topical application of the extracts significantly delayed hair graying and increased the number of hair follicles and the depth of the hair follicle in the anagen phase, suggesting potential benefits for hair growth and color retention.

    This review article summarizes the pharmacological properties of rosemary and its therapeutic potentials. The authors mention that rosemary is traditionally used to promote hair growth and as a remedy for baldness. However, the article does not provide specific evidence of its effectiveness for these purposes.

Lavender Oil


  1. Lee, B. H., Lee, J. S., & Kim, Y. C. (2016). Hair growth-promoting effects of lavender oil in C57BL/6 mice. Toxicological Research, 32(2), 103-108. doi:10.5487/TR.2016.32.2.103

    This study investigated the hair growth-promoting effects of lavender oil in C57BL/6 mice. The authors found that topical application of lavender oil promoted hair growth by increasing the number of hair follicles and deepening the depth of the hair follicle.

  2. Mori, H. M., Kawanami, H., Kawahata, H., & Aoki, M. (2016). Wound healing potential of lavender oil by acceleration of granulation and wound contraction through induction of TGF-β in a rat model. BMC Complementary and Alternative Medicine, 16(1), 144.

    This study examined the wound healing potential of lavender oil in a rat model. The researchers found that lavender oil promoted wound healing by accelerating granulation tissue formation and wound contraction. The study suggests that lavender oil may have potential applications in skincare and wound healing due to its ability to promote tissue repair.

    This study investigated the effects of lavender oil on stress, bispectral index values (a measure of sedation), and needle insertion pain in volunteers. The researchers found that the application of lavender oil reduced stress and increased skin blood flow, suggesting that lavender oil may have a positive effect on skin blood flow.
