Something I've pondered on for a while and that is my main fursona's hairstyle. For the longest time, her hairstyle has been the ones on the top, but I've decided to give her more styles and colors in case I tire of her default look (again, the two at the top). This ref pretty much shows the styles she goes through during the year. Left is what it looks like tied back and right is when her hair is down.

Spring (also her default hairstyle):
Hair is wavey/curly and long. Her hair length ends halfway down her back. When she ties it back, she straightens out two thick locks that dangle at both sides of her face.

Summer:
Her hair color starts to look lighter because of the sun. She has darker patches where her highlights used to be and on the tips. She also has her hair cut shorter than before, length going a little past her shoulders.

Autumn:
Hair returns back to Spring/default color and length but is now straight instead of wavey/curly. She sometimes lets her hair grow down to her waist.

Winter:
Hair goes wavey/curly again, but is now dyed red.

And that is all that needs to be known about her hairstyles. Whatever look people go for when they draw her, the most important thing of all is the hair curl at the left side of her face and the curly lock that sticks up. Highlights are a must to remember too (some people seem to forget that).
