How Long Can Your Hair Grow in a Month?
Human hair grows at an average rate of half an inch per month, or around six inches per year. Straight hair will tend to show growth more clearly than curly hair due to its nature; however, results will be more or less the same, regardless of your hair type. As well as genetics and lifestyle, your age will also have an effect, as well as any underlying hormonal issues, medical conditions and medications or supplements you may be on.
