There may be fewer surprises.
Because hair is so stretchy when wet, it looks much longer, and this is especially true for people with very curly hair, says Labrecque. Cutting the hair when it's already dry allows the stylist to trim just the right amount off – and eliminates the shock factor that can come right after a cut, when it can bounce up way more than anyone expected. What you see is what you get when you cut it dry, and that can cut down on any miscommunication between client and stylist, says Ungaro.
