LUSH Daddy-O purple shampoo for blonde/gray hair. This is one of the best purple shampoo's I have ever used, and the fact its all natural, vegan friendly and no animal testing makes buying it even easier! I prefer to use it once to twice a week just to keep my blonde fresh.
My great grandmother said that her mother used to do this. When she died she didnt have a gray hair. Teabagging your hair! Blondes: Chamomile; Red: Rooibos; Brunette: Black. Once a week, steep 2 tea bags in 2 cups boiling water for 10 minutes. Let the liquid cool to room temperature. Pour the mixture over wet, just-washed hair, rubbing it through the way you would shampoo. Leave the rinse on for 10 minutes; wash and condition to seal in the silky, glossy results.
