To tell you the truth I believe that if a hairstyle has to become a trendy hairstyle it is just a question of styling products. The trick is to know how to choose the right styling product. So many different styling products are available that you may find yourself lost in the world of styling products. You may buy anything from molding paste, to hair mud. You can even make a trendy hairstyle by yourself. You just need to put any smelly stuff you find around you on your hair and you are ready. You just created the perfect trendy hairstyle.
I keep my trendy hairstyle for seven years now. May be you will say, "Seven years? Oh, it is not already a trendy hairstyle! This is your grandma's hairstyle!". Okay, I know, I won't get offended! I know my hairstyle will not be a trendy hairstyle forever. But I do not want to change it. I love my trendy hairstyle. I still think that it is a trendy hairstyle.
I will set your minds at rest with another story of a trendy hairstyle. I used to know a woman who loved her 80's bug hairstyle with large quantities of hair spray. Why did she love her hairstyle? We won't probably understand her. But I believe you met such strange people on the streets every day. Hairstyles from 70s and 80s are getting more and more fashionable.
