Beards are determined by genetic inheritance, including the age at which they start to grow, the speed of growth, the size, thickness, and coverage (such as whether it is a beard or a mustache). These are all genetically established codes in an orderly manner. It is difficult for acquired factors to change this process.
Acquired nutritious diet, exercise, shaving, massage, and nutritional solutions will not change the original genes of the beard, nor will they promote the growth of beard.
Some people say that male hormones can be supplemented. It is true that beard growth requires the support of male hormones, but this does not mean that the growth process and thickness of beards have anything to do with the level of male hormones. Increasing male hormones will not increase beard growth in men! Increasing male hormones in men will not make beards thicker or make beards appear earlier!
There is a hair growth liquid drug called Minoxidil on the market. This drug can indeed make some people's beards grow longer, as if it changes the beard genes, but this drug changes a certain aspect of the body. There are side effects such as heart palpitations, skin swelling, etc., so it is not recommended to try it.
Beards are also a product of men’s aging. The appearance and quantity of beards are directly proportional to age. The older you are, the more beards you have. So the only secret to growing a thicker beard is to wait until you get older.
