It doesn't have to be long. I've done blowouts on all lengths of hair. Including pixies. Blowouts are not only great for a super cool look, but with the right products your hair will feel amazing. Most of my clients get 2-4 days out of a blowout, but I have women that stretch it 7 days with the right hair care routine. Even as the style relaxes and the curls may fall you still have hair that has body, volume, and movement and smells good depending on the products. So whether your hair is long or even if it is short, a blowout will work just fine.
