One of the most important causes of hair loss is improper nutrition, poor quality shampoos and hair care products. Hair loss is largely caused by hereditary reasons, but vitamin and mineral deficiencies caused by malnutrition are also known to cause hair loss. Male pattern baldness is caused by increased testosterone levels during puberty. High fat based on animal food can negatively affect hair follicles by increasing testosterone levels. Protein and B vitamins taken through daily diet are very important for hair strands consisting of protein. This protein can be taken from beans, lentils, yoghurt etc. instead of fatty foods. Green leafy vegetables rich in iron can stop hair loss due to iron deficiency. You can make your hair healthier with fruits containing vitamin C such as oranges, grapefruit, watermelon, strawberries. Nuts such as walnuts, hazelnuts, almonds, peanuts give hair a natural shine, while peanuts are rich in iodine, which prevents thyroid gland problems that cause hair loss. Pumpkin seeds: rich in omega 6 fatty acids, protein, zinc and iron and all these minerals help to maintain hair health. Consuming one egg every day or every other day meets your b12 need. Fish consumption is also important for hair health. You can get omega 3 fatty acids and b12 vitamins by consuming salmon or herring at least twice a week. Oats prevent hair loss thanks to its high content of vitamin B, zinc, protein and copper. It is also rich in minerals important for hair growth such as potassium, phosphorus, magnesium and iron.
