| Summary: | In society, hair serves as more than just a biological feature. It is regarded as an
essential tool for self-expression and holds cultural significance in many social circles.
The unique structure and diverse composition make hair a versatile material, and
many common hair treatments make use of this unique property to change its texture
or colour. Photodegradation of hair is an unavoidable consequence when exposed to
UV in the atmosphere in daily life. Extensive research has explored the impact of UV
radiation on different hair types, recognizing its role in altering hair morphology.
However, there remains a significant gap in understanding the impact of UV on
cosmetically treated hair and the extent of this impact on photodegradation. Therefore,
this study explored the impact of cosmetic treatments like thermal treatment, chemical
treatment, and bleaching alone on hair morphology using scanning electron
microscopy (SEM). Further, to evaluate the impact of UV on cosmetically treated hair
morphology, cosmetically treated hairs were exposed to UV light for different
durations. The results revealed that processes like dyeing and bleaching confer some
level of photoprotection against long-term UV exposure, while thermal treatments
exacerbate the deleterious effects of UV irradiation. This indicates the complex
interplay between cosmetic treatments and UV exposure on hair health. This study
provides valuable insights into the synergistic effect of both hair cosmetic treatment
and UV light. Further research is needed to fully understand the extent and
mechanisms of UV-induced protein damage, which is crucial for developing effective
strategies to protect and maintain hair health under sun exposure and cosmetic
treatments |
