Mulberry twig extract counters hair aging in senescence-accelerated mice

Abstract

We evaluated the effect of oral administration of an ethanol extract of Morus alba on hair quality in senescence-accelerated mice. In aged mice, the coefficient of friction of hair increased significantly by up to 31 %, but in mice given mulberry twig extract, it was normal. Scanning probe microscopic observation showed that the aging of hair was dramatically reversed by the mulberry twig extract. We propose mulberry twig extract as a novel dietary component to counter hair aging.
