Colgate is completely a fake brand. Its promises are all fake . In 1917, when colgate came to India . At that time all indians used to clean their teeths throughsalt and charcoal. And At that time , The brand said that it harmful for our health and duggests to use their product and Nowadays, colgate iis advertiding its product by saying that it has salt which cleans our teeths . Some toothpastes of its have charcoal which they say make our gum strong. So I am totally against the use of colgate. And recommend you all to not to use the colgate products because they do anything for their profit.
