Given the currently available treatment options it appears that the premature greying process cannot be reversed. There is no scientific evidence that any existing medicine, herb, dietary supplement or natural product can prevent or reverse greying hair. Several cosmetics and pharmaceuticals firms are working on the discovery of the ultimate cure for grey hair but no satisfactory solution is commercially available yet.
Gray hair is often associated with thyroid problems, excessive stress, bad diet, vitamin B deficiency and smoking. The fact is, however, that the number one cause for premature greying hair is genetics. The pigment that determines the colour of our hair is produced by special cells at the root of our hair called melanocytes. It is the lifespan of melanocytes that determines the beginning of the greying process. Once these cells die, the hair turns white.
There is no essential difference between a premature and a normal age-related greying process. It is by virtue of nature that some people will experience their first white hair in their teens and turn completely grey in their early thirties, while others will keep their original hair colour for many decades. If more than 50% of a person’s hair is white by the age of 40, it is regarded as premature.
There are some commercial products out there that claim to be able to rejuvenate the dead pigment-producing cells and reverse premature grey hair. Such claims, however, are largely unsubstantiated. The truth is that at this point in time no remedy exists that can reverse the greying process. Most of the anti-grey hair products either use Fo-Ti, referring to the centuries old legend of Mr He, who recovered his original hair colour, vitality and youthful appearance thanks to this traditional Chinese medicinal herb, also known as He Shou Wu or use vitamins B (mainly folic acid and PABA) as their main ingredients, since some forms of premature greying are associated with vitamin B deficiency. However, such products are ineffective for the majority of premature grey hair sufferers. (in case you are interested in how to get rid of hair dandruff you may like to check our article
Hence, the only option for treating premature grey hair that seems to deliver guaranteed results is camouflage. Women use various types of permanent, semi-permanent and demi-permanent hair dyes but men usually prefer a subtle and less noticeable change in their hair colour that does not cover all their grey hair. Such products are usually called progressive hair colorants. It is obvious that none of these products can make the dead cells produce pigmented hair and thus they must be used continuously to cover the grey of fresh hair. Although there are some natural hair dyes that claim to effectively cover your grey hair, the products that really work well all use certain chemical substances. When deciding about hair dyes or progressive hair colorants, you should always consider the potential health risks, as most of them contain chemicals that can cause poisoning if used inappropriately or can lead to severe allergic reactions. You should always use a patch test before applying any such product and follow the application guidelines in order to minimise exposure to aggressive substances.
