Is it good/ bad for a 15 y/o to do this? *10 points*?

Yeah its bad to loose weight at your age, you grow outward before you go upwards as your body is creating fat stores. Also it is natural for women to have more fat than woman because women have fat stores on places such as the *** and boobs, men collect fat round the organs. But there is nothing against what you do with your face or hair you won't hard yourself but avoid the dieting and too much intenser exercise.
