More and more "Hair Loss Treatment" ads on Yahoo!

A few weeks ago, I saw "Svenson Hair Care Center" on Singapore Yahoo when I was opening Yahoo! Mail. Today, upon opening Yahoo! Mail, I saw another similar Hair Care Center ad, "Trichokare Hair Loss Solution". Hair care center seems to promote widely these days. And seems that more and more are opening all around the world. They even give Hair care shampoo for free on every visit of hair care. It seems that such hair problems grow in every country every year. Does it mean that this hair loss problem getting serious?
