Cyndi Lauper has her platinum blonde hair cut in an inverted bob haircut. This most flattering style has a few razored top tendrils, all to keep her look up to date.
A "quiff" is the name of this particular hairstyle with the inspiration coming from the 1950 pompadour look and then combining it with a mohawk finish. However, Cyndi Lauper likes her unforgettable signature hairstyles, and though she has a modern day accent with these wavy wisps, she took this style to the extreme so we categorize this as Freaky Friday.
There are messy styles and then there are "Messy styles. Anytime you take the 'bedhead' seriously, it will definitely be considered a Freaky Friday.
A short, spiked style on Cyndi Lauper is highlighted all across the front hairline, as you can see, with bright purple haircolor, very possibly done with temporary spray. We certainly see her "true colors shining through" with her Freaky Friday style.
