Although some women look at grey hair as a “badge of courage” or an indication of wisdom, many more see it as simply making them “look old.” Most immediately head for the hair dye aisle of the local shop, make an appointment with their hairdresser, or resort to plucking out individual hairs until they can no longer keep up; but there are other options as well.
Although it’s not possible to permanently prevent your hair going grey; you may be able to delay it, slow it down, or even stop it in its tracks and restore your natural color, at least for a few years. A few common reasons for your hair going grey include:
- genetics and aging
- high levels of stress or worry
- smoking
- Vitamin B12 deficiency
- thyroid disease, such as:
- Grave’s disease
- Hashimoto’s disease
- hyperthyroidism
- hypothyroidism
- Early menopause




The cause of gray hair is simple. An amino acid called methionine interacts with the hair follicle. Low methionine means that the follice’s pigmentation mechanisms fail. All of the risk factors above are valid, but that’s because they reduce methionine levels in the body. No amount of avocado oil is going to help. Since hair cells do not carry out metabolic processes no topical treatment for hair will help. What will help is increasing the amount of methionine in the diet, through eating more protein or through supplementation with L-methionine.
