The age at which a girl should start shaving her legs is a personal decision and can vary depending on cultural and individual factors. However, some girls may start shaving their legs around the age of 12 or 13, when they begin to notice hair growth on their legs. When starting to shave, it is important to use the correct supplies and techniques to avoid nicks, razor burn, and skin irritation. Here are some tips for shaving your legs:

• Supplies: Use female razors with a rounded head and a curved handle that are made to help you access those trickier spots behind your knees and around your ankles. Use shaving cream or gel to soften the hair and allow for an easier glide. You can also use conditioner or body wash in a pinch.

• Technique: Shave at the end of your shower when your leg hair is soft and your follicles are open. Wash your legs with soap and warm water before shaving to prevent infections. Shave in the direction of hair growth, and go gently over the knee and ankle, which are the trickiest parts of shaving your legs. Rinse your razor between strokes and replace your razor blade when it feels dull. Rinse your legs with cool water after shaving to close up your pores.

• Skin care: Exfoliate your legs before shaving to lift dead skin cells from the surface and allow the razor to get super close to the root of the hair. Use a gentle physical body polish or an exfoliating body wash that contains glycolic or salicylic acid. After shaving, rinse any remaining oil and soap off your legs, dry them off, and put on some soothing moisturizer on the areas you shaved.

It is important to note that these tips are general guidelines, and everyones skin is different. It may take some trial and error to find the best shaving routine for you.
