Thinning hair is generally caused by two factors: loss in hair density, that is to say less hair per cm2, and a smaller hair diameter. The time when hair starts thinning has many factors: family history, age, diet, stress, hormones or even lifestyle habits are part of the long list of factors.
Technical expert in hair care, the L’Oréal Professionnel hairdresser can carry out an in-salon diagnosis to determine both the hair type and thinning hair causes, and recommend the tailored professional fuller hair treatment. The hairdresser is able to feel and see how thick and long the hair is both in terms of diameter and the quality of lengths and ends. He then checks hair root density and volume by gently running his fingers through the hair.
