So I'm really giving you PICTURES!!! lol, this style is super easy to do AND will work on a variety of hair lengths. I did this on braid-out hair and used bobby pins to hold my hair down. I just folded my hair to create the scales. You can choose to add more/less dinosaur scales/layers. I was in a hurry and kept it simple with 3 layers. I can imagine me trying this style again with 10 layers...SUPA DUPA CUTE!
Finally, if you want a more "polished look" you can also opt to pin back the front/bangs portion to achieve the look below.
Have an awesome weekend! PS - I did find out some interesting things on water chemistry as it relates to hair, look for that post next week!
