The “Garden Secret” for Scalp Vitality: Homemade Rosemary Oil
The Science Behind Rosemary Oil
Why is rosemary oil suddenly the “it” ingredient for hair?
- Blood Circulation: Rosemary is known to improve blood circulation to the scalp. By increasing local blood flow to the hair follicles, it may help ensure follicles receive the oxygen and nutrients needed for healthy hair growth.
- DHT Blockage: Research has suggested that rosemary oil may help inhibit the effects of dihydrotestosterone (DHT) on hair follicles. DHT is a hormone derivative that, in genetically susceptible individuals, can cause hair follicles to shrink, leading to thinning hair and pattern baldness.
- Comparative Efficacy: A well-known 2015 study compared rosemary oil to minoxidil (a common hair loss treatment) in individuals with androgenetic alopecia. After six months, both groups saw a significant increase in hair count, with the rosemary group experiencing less scalp itching.
