Shaving is the cheapest way and less painful. People believe the myth that if you shave your hair it grows back faster and thicker and more hair growth comes in. I have been using a razor to shave my eyebrows, side burns and my little mustache hairs since I was 14... If anything, the hair has become thinner! When you shave, you only cut the surface of the hair off. You aren't cutting the bulb (below the skin) which would effect the size, color ect. of the hair. That is where the hair growth happens. When you wax and tweeze hair, you remove the bulb which in fact will make the hair grow back in thicker over time. Shaving may not last as long but it is safer then putting chemicals on your face! Also, there is no possible way either shaving, tweezing or waxing causes more hair growth. Hormones and nutrition are responsible for this.
