Recent studies reveal that haircutting and hairstyling were practiced in some form as early as the glacial age. The Egyptians were the first to nurture beauty in an extravagant fashion, and became well-versed in the art of makeup and hairdressing. The ancient Egyptians were also the first to use cosmetics as part of their personal beautification habits. The 19th century was the era of research and innovation that saw many changes in the field of hair care. In the 20th century, hairstyling began to follow trends, and soon became available to the masses that could then choose their styles based on their individual needs and desires.
