Almost everyone has probably had their hair cut too short at some point. But don't worry — here are some simple ways to fix a haircut that's too short and get your confidence back .

A bad haircut is disappointing, but there's no need to be sad about it for too long. Your hair will eventually grow back (obviously), but waiting for that to happen can be easier said than done, especially if you've had a bad haircut.
The good news is that people have found ways to deal with bad haircuts. Here are the most effective ways to deal with hair that is too short.
How to fix hair cut too short
Talk to your stylist
Having open communication with your stylist can go a long way, so be upfront about your feelings. A good stylist knows that their haircut is for the client, not the stylist. The beauty of the job is making people feel good about their hair. Most professional stylists want the opportunity to fix your hair and make sure you're happy, [possibly] by offering a discount on a service or product
If you do not receive satisfactory feedback, you should change shops or hairdressers.

After talking to your barber, you may choose to get a second opinion from the owner or a more experienced barber. If you feel like you and your barber are not on the same page, there may be someone else nearby who shares your point of view. Most experienced barbers are not only better at their craft, but also have a better understanding of their clients’ wants and needs. The more experience a barber has, the better able they are to help you make the best choices. Don’t be afraid to get a second opinion – invest in your haircut.
To grow hair back
Obviously, you have no choice, and sometimes patience is the best option. Have you ever cut your hair much shorter than you wanted, only to realize it was too late and there was no going back? It must have felt like the end of the world. But what you shouldn’t do is fix your hair yourself. This can often make the cut much worse and the time it takes for your hair to grow back can be much longer.
Letting your hair grow back after a bad haircut may not seem like the ideal option, but depending on how you cut your hair, it may be the best solution. While hair doesn’t grow quickly, your stylist can usually make some adjustments to help your hair grow out more easily.
Hair extension
Hair extensions can add length and volume to a bad haircut, helping to repair damage while your hair grows out. Maybe your stylist cut it a little too short. Maybe your layers are too much, but if your haircut is too short, extensions are the quickest fix. These neat little clip-in pieces are super easy to use for beginners, no previous experience necessary. Extensions can add length and/or volume, and they can also help to blend in a bad haircut. Plus, they’re actually pretty fun to wear.
Use hair clips and hats
Accessories can be a great way to cover up any minor issues with your hairstyle. Bangs not flattering? Go for a ’00s bouffant. Layered hair? A fun back-swept hair clip can add a little extra flair to your half-up look without much time or effort.
