A good hair is what everyone likes to have. A long and soft one without any breaks and shiny too. But just liking will not do any thing. The idea is to stop causing damages to hair. Damage is caused by pollution and chemical agents. But what we see in real life is that we use shampoos that contain chemicals that cause harm to the hair.
So when you use a hair shampoo, make sure that you use the one that has less chemical content in it or better use the one that is free of chemicals itself. This could greatly reduce the damage that is caused to the hair by yourself. Use a herbal shampoo instead of the standard chemical ones.
