You do not need any fancy styling products to style short hair. The anti-frizzing products that you would use on hairstyles of other lengths can also be used on short hair. Some products will lock the hair in place, and create a smooth style. This can help to produce some impressive hairstyles. For straightening or curling your hair, there are styling tools available that are compact enough to use on short hair, such as the Sedu range. Caruso hair setters are similarly compact.
As long as you choose the right style, short hair can be very flattering and feminine. Celebrities such as Natalie Portman and Halle Berry have shown that short hair does not automatically mean a masculine appearance. Take some time to find a style that you like, and seek advice from an expert if you are unsure, as a short hairstyle is a big transformation.
