Apart from the smooth/ curly hair (which might be down to the way they look on camera, with bright screens behind, and/ or the need to keep the look consistent day after day) - how the percentages you gave compare with the rest of the population? For example, most women have short or medium-length cuts. Nearly half are blonde (or dye their hair blonde). Almost all women keep dyeing their hair in their 70s. Etc. Btw, when's the last time you saw a man tv anchor with long hair? Or curly?
