Help may soon be at hand for those who are losing or have lost their hair.  team of Japanese scientists has discovered stem cells that are vital in  hair regeneration process. This is promising news for  millions of people worldwide who suffer from baldness.  cure has eluded scientists for decades, despite extensive research and significant investment in research.  scientists are now embarking on clinical research and laboratory trials. They hope to adapt  stem cells to finally create  therapy for hair loss. Baldness predominantly affects men. By  age of 35, around two-thirds of men will experience some degree of hair loss. By  age of 50, up to 85 per cent will experience significantly thinning hair.
 scientists took fur cells from mice and cultured them in  lab. They observed that hair growth was  cyclical process within the follicle. They analysed  stem cells and used 220 combinations of chemicals to make  hair regrow naturally. Lead scientist Takashi Tsuji said: "Our culture system establishes  method for cyclical regeneration of hair follicles from hair follicle stem cells and will help make hair follicle regeneration therapy  reality in  near future." He added: "Losing hair is not life-threatening, but it adversely affects  quality of life." Sam Baker,  52-year-old bank worker, hopes the therapy works. He said: "Having  full head of hair again will make me look ten years younger".
