Prevention of graying hair is one thing and TREATMENT another. Emu Oil suggestion by an answerer is well taken but again it is only for preventive purposes and is NOT curative.
The only known NATURAL thing known to TREAT premature graying of hair and even reversing it is Fo-Ti. It’s also called Hu Shou Wu and has been researched in the western countries for this fact. This herb also has various other benefits for human metabolism and gets a safe solution i.e without any chemicals; so no side-effects.
Talking of hair health, what you should be looking for are natural products only – not the ordinary, so-called, namesake herbal ones but REAL ones. What you should be looking for are special ingredients like Kelp, Saw Palmetto, Nettle, Roobois extract, etc that help for healthy hair. These and many more important things for hair and scalp are available in various forms in the Segals Solutions Program. It’s now available in India and is perhaps the best quality product that can be thought of. All natural extracts, no harmful chemicals. Incredible results.
Advise you to appreciate that it has so much in it which none else has. Make an honest independent study and check for yourself. Or you may speak to their helpline to get any advice about hair-health. It’s doesn’t cost anything and is really encouraging.
P.S: More than Emu Oil, what will moisturize your hair is Hempseed Oil, Jojoba Oil, Shea Butter, Hydrolysed Wheat Protein and Comfrey extract. Again, all these form part of the Segals Solutions.
