【 摘 要 】

There are few studies that characterize the non-pigmented hair compared to pigmented hair. Furthermore, it is important to evaluate how the natural process of aging hair influences quality of life in women. For this purpose, a questionnaire was applied to evaluate the impact of greying hair and the appearance alterations on women´s self-esteem. The satisfaction level of volunteers regarding their hair structure and conditions such as shine, strength and smoothness were also evaluated. Mechanical properties, such as elasticity and traction to rupture were measured using Universal test equipment. Scanning electron microscopy (SEM) was used to measure the hair surface morphological conditions. A large majority of the volunteers indicated that the beginning of greying hair can negatively influence their quality of life. They also reported that the primary changes of their hair were the frizziness, dryness and loss of shine, increased loss and breakage and thinning. Morphological evaluation showed that the non-pigmented hair cuticles were thinner than pigmented hair. The adherence of the cuticle scales was more pronounced in the non-pigmented hair .Finally, this study showed the influence of the appearance of grey hair on quality of life in women as well as the morphological alterations resulting from the greying processes.
