Focus on the virtues or benefits of rosemary essential oil on hair.

The essential oil of rosemary has positive effects on the scalp and hair fibre. Its benefits are as follows:

  • Thanks to its anti-inflammatory properties, it soothes sensitive scalps that are prone to itching and dandruff;

  • Thanks to its antioxidant action, it prevents hair loss. Indeed, oxidative stress damages the hair follicle, which weakens it and promotes hair loss.

  • Its antioxidant action also helps to prevent the premature onset of grey hair. Indeed, free radicals produced during oxidative stress can trigger a cascade of reactions leading to the degradation of melanin, a pigment responsible for the colour of our hair.

  • A study has shown that rosemary essential oil improves blood circulation in the scalp. Indeed, it was demonstrated that in patients suffering from androgenetic alopecia, rosemary helped to enhance blood flow and vascularisation, aiding in the regeneration of follicles.

  • Several studies have suggested that this essential oil could stimulate hair growth, but the exact mechanism remains uncertain, making a definitive conclusion on this property difficult. However, it appears to be effective in preventing hair loss.
