Beard growth in men is a very common phenomenon, especially among adolescent and young adult males. As men age, the rate of facial hair growth typically decreases; however, some individuals may retain a full beard for their entire lives. Factors such as genetics, diet, hormones and lifestyle choices can influence the speed at which facial hair grows in each individual. Additionally, men's choice of grooming practices can affect the way that their beards grow in terms of both length and texture.


From an evolutionary standpoint, it is believed that beards evolved to help protect males from environmental hazards while they hunt and perform other activities. Modernly speaking, beards have become fashionable again, with many young men sporting thick or sculpted beards as a form of self-expression. Proper maintenance is necessary to achieve these desired results and will often involve brushing, trimming and waxing as needed.
