Rosemary helps hair growth primarily by improving scalp circulation, which ensures hair follicles receive adequate blood supply and nutrients. This prevents follicles from dying off and supports the growth phase of hair
. Key ways rosemary supports hair growth include:
- Enhancing blood flow: Increased circulation nourishes hair follicles, promoting healthier and longer hair growth
- Anti-inflammatory and antioxidant effects: Rosemary contains compounds like carnosic acid that reduce scalp inflammation and oxidative stress, creating a healthier environment for hair growth
- Potential DHT blocking: Some evidence suggests rosemary may inhibit dihydrotestosterone (DHT), a hormone linked to hair loss, helping to prevent follicle shrinkage and hair thinning
- Antimicrobial properties: These help reduce dandruff and scalp irritation, further supporting scalp health and hair growth
Clinical studies have found rosemary oil to be as effective as minoxidil (Rogaine) in treating androgenetic alopecia (pattern baldness), with fewer side effects like scalp itching
. Typically, rosemary oil is used by diluting a few drops in a carrier oil and massaging it into the scalp or adding it to shampoos and conditioners for regular use
. In summary, rosemary promotes hair growth by improving scalp circulation, reducing inflammation, potentially blocking hair loss hormones, and maintaining scalp health, making it a natural and effective option for supporting hair regrowth.
