A very simple trick can tell you whether your hair is damaged or not. Many of you might already be aware of this. But, for those who are not, you can take a test.
Comb your hair and pick one strand of your hair from the comb. Drop it in a glass full of water. If the hair sinks, your hair is damaged. And, if it stays afloat, your hair is healthy. Caution: Do not pluck hair from their roots just to do this experiment. Plucking the hair damages its follicle and can impede future hair growth.
