This study aims to determine the effects of UV types on permed hair. According to an analysis of changes in wave continuance by the type of perm agent and UV type, hair shape and physical properties when UV rays (A, B and C) with different wavelength were applied to permed hair, the wave continuance degree by UV irradiation further declined in UVB and UVC irradiations compared to UVA in ‘C’ perm. In ‘T’ perm, UVA was the lowest, followed by UVB and UVC in terms of wave continuance degree. The physical properties were significantly lower in UVC irradiation than UVA and UVB irradiations in perm agents. However, the damage rate in ‘T’ perm was greater in UVB and UVC irradiations than in UVA. According to an analysis of the type of perm agent and UV type, UVA was the lowest, followed by UVB and UVC in terms of wave continuance and hair physical properties, while elongation rate was the lowest in UVC irradiation rather than in UVA and UVB. According to an analysis of scales on the hair surface, the damage degree of the hair surface in ‘T’ perm agent under UVC irradiation was particularly high. The wave continuance degree and physical hair properties by the type of perm agent were significantly decreased in ‘T’ perm agent, more so than ‘C’ perm agent. In summation, both the type of perm agent, UV irradiation time and UV type had a considerable effect on wave continuance and hair physical properties. Specifically, ‘T’ perm agent and UVC had the biggest effect on wave continuance degree and hair damage degree.
