A prematurely discoloured (whitened) hair was washed bi-monthly five times; then daily five times and with five dilutions of the same Vernonia amygdalina aqueous leaf extract. The results of the hair treatment with V. amygdalina leaf extract (washing with the extract) showed that V. amygdalina leaf extract produced a concentration and frequency of application dependent restoration of the natural dark colour of the whitened hair. It also restored original hard texture, body form and lusture of the hair which was lost when the hair whitened.
