Growing out short hair is a process that requires some patience. Hair grows at an average rate of about 1/2 inch a month, so plan on spending some time in the transitional stages between short and long locks. While proper nutrition can help your hair's health, sadly there is no real way to speed up the growth process. You can, however, take some steps to make the growing out process a little more bearable.
Maintain hair health by using a good quality conditioner, avoiding harsh chemicals like relaxers and bleach, and minimizing heat damage. If you use a blow dryer, curling iron or flat iron on your hair, invest in a heat protection spray. Weak and damaged hair will break and split, prolonging the grow out process.
Visit your stylist every six to eight weeks to get a routine trim if you have split ends. Ask your stylist to cut off a minimal amount, less than 1/2 inch. You don't want to sacrifice any more length than necessary; just remove the damaged ends to prevent them from splitting and breaking even further.
Purchase some cute barrettes, headbands or maybe even a hat or two. If you're starting the grow out process with very short hair, such as a pixie cut or any other layered or choppy short style, there will most certainly be some awkward phases. Clip back bangs that are growing out, so you aren't tempted to cut them off, or use a headband or scarf to keep short, unruly strands out of your face.
Find a picture of the hairstyle you're hoping to achieve. Setting a definite goal will help you stay motivated, even when you're having a bad hair day.
Consult your stylist if your in-between locks start to feel too unmanageable. Explain your situation, making sure to mention you don't want to lose any of the growth you've worked so hard to achieve. Your stylist may be able to reshape your cut without taking off too much length.
