Technologies are generally described for measuring hair condition using a hair condition measuring device. Example devices and systems described herein may include a first clamp, a second clamp, a vibrator, a laser beam source, a photodetector and/or a processor. The first claim may be configured to clamp a first end of hair, and the second clamp may be configured to clamp a second end of the hair, so that the hair is stretched between the first clamp and the second clamp. The laser beam source may be configured to generate a laser beam toward the hair. The photodetector may be configured to detect at least part of the laser beam reflected by the hair and convert an intensity of the detected part of the laser beam to an electrical signal. The processor may be configured to measure condition of the hair based on the electrical signal.
