I've been recommended so many different kinds of shampoo and conditioners to make my hair shiny and soft, but they haven't worked. I want soft, easy, manageable hair!

My hair is really thin. Do Dove products work well?

Could you give me pointers on how to maintain glossy, silky hair?
Thanks!

The best way to maintain thin silky hair is to throw out all the shampoo and air conditioners you use which have chemical contents. For a typical shampoo, you can see more than 30 chemical contents in it which may be harmful to you.
Silky hair is attractive but more prone to damage. So try using herbal remedies for it. There are a lot of available herbal oils and treatments for your problem.
