Common ways of thickening facial hair include eating a protein rich diet and taking vitamin and mineral supplements. Many men also experience success when massaging the face periodically or changing their exercise routines to stimulate testosterone levels. Higher levels of testosterone levels are associated with thicker facial hair.
Hair is composed of protein, and eating a diet that is high in protein is one of the key ways to grow a fuller beard. Protein-rich foods include fish, eggs and lean meats. For those who follow a vegetarian or vegan diet, eating more beans and greens, both of which are high in protein, is necessary. Another important dietary step to growing fuller facial hair is supplementing the diet with vitamins and minerals. Dermatologist Jeffrey Benabio recommends taking biotin supplements. Vitamins B6, C and E are also said to stimulate the growth of thicker hair.
In addition to dietary changes, it is possible to encourage facial hair to thicken by massaging the face once a day. This draws more nutrient-rich blood to the area, encouraging rapid growth. Shaving too often weakens the hair shafts, discouraging growth. This is a common mistake among men who have been misinformed that shaving more often encourages the hair to thicken.
