Growth problem. Very patche and short!

The beard of a person is determined by his or her genetics, and it is believed that a person starts growing facial hair in the later years of puberty or adolescence, between seventeen and twenty years of age, and most do not finish developing a full adult beard until their early twenties or later. I would advise you to follow a good lifestyle and eat healthy. These following steps may help: - Drink lots of water and stay well hydrated at all times of the day(Aim to drink 2.5-3 liters of water everyday) - Don't skip meals, Eat healthy, clean and nutritious diet, Don't crash diet - Eat iron rich food, calcium rich such as milk, dairy products - Adults need upto 8 hours of sleep per night - Destress yourself with methods such as yoga/meditation. - Exercise regularly (minimum 30 mins) You can check your testosterone levels, thyroid profile and calcium levels and accordingly have a supplement. If problems persist or worsen visit an endocrinologist.
