My 14 year old grandson is going to look splendid in his Christmas blazer,French blue shirt, and Gucci tie. My next step in helping him grow up is the taming of his soccer-mop hairdo. I see the big mop of hair on many soiccer players in newspaper photographs, so I understand his inspiration. Can anyone suggest a shampoo that will help keep the mop orderly? His hair is medium thickness, with a slight curl at the ends, which makes things look disorderly. Or.....is the problem the haircut itself?
