Hair is very sensitive to internal alterations and so a lack of sleep triggered by stress, can be followed by the onset of an accelerated hereditary loss of hair. According to Clinical Director of the Institute of Trichologists and Nioxin expert, Keith Hobbs, this can be explained by the fact that “Cells are regenerated during sleep and deprivation will affect the health of your hair. In many cases, a correct diagnosis from a qualified member of the Institute of Trichologists can be followed by treatment and a successful outcome”
