title: Study of colouring effect of herbal hair formulations on graying hair.
abstract: OBJECTIVE
  To screen the hair colouring properties of hair colorants/ herbal hair colouring formulations.
  
  
  METHODS
  The dried aqueous herbal extracts of Gudhal leaves (Hibiscus rosa-sinensis), Jatamansi rhizome (Nardostachys jatamansi), Kuth roots (Saussurea lappa), Kattha (Acacia catechu), Amla dried fruit (Embelica officinalis), were prepared. Coffee powder (Coffea arabica) and Henna powder (Lowsonia inermis) were taken in the form of powder (# 40). Fourteen herbal hair colorants were prepared from these dried aqueous herbal extracts and powders. Activities of hair colorants were observed on sheep wool fibers. On the basis of the above observation six hair colorants were selected. These six formulations were taken for trials on human beings.
  
  
  METHODS
  The formulation coded HD-3 gave maximum colouring effect on sheep wool fibers as well as on human beings and percentage of acceptance among the volunteers were in the following order: HD- 3 > HD- 4 > HD-1 > HD-13 > HD-14 > HD-11.
  
  
  CONCLUSIONS
  The remarkable results were obtained from five herbal hair colorants, viz., HD-1, HD- 3, HD- 4, HD-13 and HD-14 on sheep wool fibers and human beings. Formulation HD-3, having gudhal, jatamansi, kuth, kattha, amla, coffee and henna, was the maximum accepted formulation and suggested that these herbs in combination acts synergistically in hair colouring action. It also concluded that jatamansi, present in different hair colorants, was responsible to provide maximum blackening on hair.
