Some active ingredients in rosemary, such as volatile oil and antioxidants, may have certain effects on stimulating scalp and promoting blood circulation, and may have certain effects on hair health. In addition, rosemary has anti-inflammatory and antibacterial properties, which helps to reduce scalp problems, such as head dermatitis and dandruff, which may also help promote hair health.
However, rosemary may not be an effective single factor to promote hair growth. Hair growth is influenced by many factors, including heredity, hormone level, health status, diet, lifestyle and so on. Therefore, if you want to improve hair health and promote hair growth, you need to comprehensively consider multiple factors.
If you have hair problems or want to improve your hair health, I suggest you consult a professional doctor or a hair transplant expert. They can provide appropriate advice and treatment according to your specific situation. In addition, maintaining good living habits, a balanced diet, proper scalp care and avoiding using too many chemical treatment and bleaching tools are also important for hair health.
