A man can grow hair faster by only brushing his hair when it's dry, rinsing the hair with cold water, and drinking plenty of water. He should avoid products that can damage the hair, such as hair dyes. Hair usually grows between one-quarter and one-half inch per month.
When hair is wet, it is more prone to breakage and split ends during brushing. Hair holds more moisture when it's washed with cold water. A balanced diet leads to healthier hair. Protein strengthens the hair, because hair strands are mainly protein. A man should also get his hair trimmed while growing it out, to cut off split ends and damaged hair.
