If you want to try an AI-powered tool to see how a new hairstyle will look before you actually cut your hair, HairstyleAI is a great choice. The service generates photorealistic images of yourself with a variety of hairstyles, letting you try different looks before you decide on a style. With 30 different AI-generated hairstyles, 4 poses and 120 high-resolution photos, you can compare and pick the ones you like best. You can upload your own selfies, and the AI will generate hairstyles that you can download. The service has a fast turnaround time and costs $9 for a single use, making it a fast and cheap option.
If you want a more general-purpose AI tool, you might want to try Lucidpic. It's mostly geared for generating hyper-realistic images for avatars, stock photos and custom characters, but you can also control every aspect of the image, including hair style. That can be handy if you want to try different hair styles within a larger creative project. Lucidpic offers a free tier for generating up to three images and subscription plans starting at $12/month, so it's good for casual and heavy use.
