Wonderful app, although if I could suggest one function for improvement, it would be to recommend hair dyes when choosing a hair color shade. I found the perfect hair color for myself with this app, but I have no idea which hair dye would carry the hair color that I like (which is a huge bummer—but I can probably ask a Sally's employee for assistance).
As far as the app as it is, I would recommend it to *anyone* who's curious as to how they would look with different hairstyles and hair colors. It's the best hairstyle transformation app on the App Store (believe me, I've probably downloaded—and deleted—all of them, besides this app of course!). The app hasn't crashed on me, nor has it malfunctioned as of yet. I really like the face shape bonus option, because I had a hard time figuring out my face shape prior to downloading this app.
I can't add constructive criticism about the customer/stylist option on the app, because I don't go to a salon for hair dying/bleaching and haven't a need for it (I do my own hair).
Keep up the great work! I hope a makeup transformation app is an idea on your bucket list!
