Hair salons in Virginia are among the best places for people to get their hair done. Hairstyles go back a long way. In Imperial Rome, hairstyles were extremely complicated. They often involved a mass of curls on top of the head. A massive hairstyle called the Tower allowed wealthy women to compete for the tallest hair in the 17th century. And hair grows fast. It is second only to bone marrow for the fastest growing tissue. To treat it, each year women spend around 160 USD on shampoo and conditioner. In India today, the chief mourner shaves his or her head ten days after a family member dies.
