Hair loss and graying worry many people, and the internet is full of herbs, oils and supplements promising to reverse both. The honest picture is more limited, and knowing it can save you money and protect your health.

Why Hair Turns Gray
Graying is mainly genetic and age-related. Colour-producing cells in the hair follicle make a pigment called melanin. As we get older, that production slows down and eventually stops, so new hair grows through without pigment and looks gray or white. Once this has happened in a follicle, no herb, cream or supplement has been proven to switch it back on.
Can Herbs Reverse Gray Hair or Regrow Hair?
No herb or supplement is proven to reverse gray hair or to regrow hair. Herbs such as He Shou Wu (also called Fo-ti) are often promoted for restoring hair colour and thickness, but there is no reliable evidence that they raise melanin levels, enlarge hair follicles or stop graying. For that reason, this site no longer recommends taking such herbs, in any form, as a treatment for gray hair or hair loss.
Are Hair Supplements Safe?
Herbal supplements are not safety-tested in the way medicines are. They can have side effects, they can interact with medicines you already take, and some traditional hair herbs have been linked to liver problems. Always talk to a doctor before taking any supplement for your hair, especially if you take other medication or have an existing health condition.
Why Hair Falls Out
Hair loss has many possible causes, including genetics, hormone changes, thyroid problems, iron deficiency, illness and stress. Because the causes differ, the right response differs too: a treatment that helps one person may do nothing for another, which is why diagnosis comes first.
What Can Actually Help?
Treatments with clinical evidence do exist for some types of hair loss, and they tend to work best when started early. A dermatologist can examine your scalp, diagnose the cause of your hair loss and advise whether treatment is likely to help in your case. Book that appointment promptly if your hair loss is sudden, patchy or rapid, or if your scalp is sore, itchy or inflamed.
Setting Realistic Expectations
Be wary of any product that promises to stop graying, reverse gray hair or regrow a full head of hair. Those promises are not supported by evidence, whatever the marketing says. Looking after your general health, correcting any diagnosed deficiency and getting an early professional diagnosis will do more for your hair than any miracle cure.
