It is a good idea to keep legs smooth the year round (not only in summer) for the sake of your own self-confidence.
Waxing: This is the most effective method for removing leg hair.
Electrolysis, of course, is the only permanent method, but waxing is certainly more practical unless you have a lot of time and money to spare. Results last for about six weeks, depending on the rate of your hair growth.
Bleaching: Not really advisable for leg hair unless it is of an extremely fine and soft nature.
Shaving: This is considered by many as the most reasonable and fast way of removing leg hair. However, this has its disadvantage as the hair has to be shaved off every other day.
Creaming: Has longer lasting effects than shaving. But it is more expensive.
