Hair care Hair care Hair care is an overall term for hygiene and cosmetology involving the hair which grows from the human scalp, and to a lesser extent facial, pubic and other body hair. Hair care routines differ according to an individual's culture and the physical characteristics of one's hair. Hair may be colored, trimmed, shaved, plucked or otherwise removed with treatments such as waxing, sugaring and threading. Hair care services are offered in salons, barbershops and day spas, and products are available commercially for home use. Laser hair removal and electrolysis are also available, though these are provided (in the US)
Laser hair removal sometimes incorrectly referred to as "laser hair removal". IPL-based methods, sometimes called "phototricholysis" or "photoepilation", use xenon flash lamps that emit full spectrum light. IPL systems typically output wavelengths between 400 nm and 1200 nm. Filters are applied to block shorter wavelengths, thereby only using the longer, "redder" wavelengths. IPLs offer certain advantages over laser, principally in the pulse duration. While lasers may output trains of short pulses to simulate a longer pulse, IPL systems can generate pulse widths up to 250 ms, which is useful for larger diameter targets. Some current IPL systems have proven to be more successful
