Some teenagers have developed a lot of white hair, with dry hair [http://www.toufa5.com], which is commonly referred to as "premature graying" [http://www.toufa5.com/baitoufa/baitoufadeyuanyin/590.html]. The causes of premature graying are numerous, such as shock, fear, mental fatigue, excessive worry, picky eating habits, nutritional imbalance, lack of certain proteins and trace elements, diseases that damage the pigment cells in the hair roots, as well as genetic factors, etc. To treat premature graying, patients should first maintain a cheerful spirit, eat more vegetables and fruits rich in vitamins and trace elements, especially those that promote the growth of black hair like black beans, black dates, black sesame seeds, and walnut meat for dry and frizzy hair [http://www.toufa5.com], to rejuvenate the hair papilla. Traditional Chinese medicine has many effective prescriptions for treating premature graying. According to clinical experiments conducted by beauty and medical experts, the traditional beauty and longevity food therapy recipe "Polygonum-cooked Eggs" has proven to be more effective in treating white hair compared to using Polygonum alone or combined with other herbs in compound formulas. The preparation of "Polygonum-cooked Eggs" is simple: take 100 grams of processed Polygonum multiflorum, two eggs, and add water to cover both (just enough to submerge the ingredients) until the eggs are cooked. Remove the shells and continue cooking for about 15 minutes, then add a little sugar, cook briefly, strain out the residue, and consume the eggs and broth. Used medicinal residue cannot be reused. This formula should be consumed no less than twice a week, and generally, effects can be seen after around 2 months of regular consumption. If it proves effective, continued use for some time is recommended to consolidate the results. Some people may experience slight diarrhea after using this formula, but this is harmless.
