Wash or wet the hair apply some product. Curl crème is not right product her as it will be too soft. I recommend a good old fashion mouse and squirt a bunch in your palm. Take a few large areas of your hair, with both hands ball scrubbing with the palms of your finger and squeeze them towards your scalp, like you are crumpling paper. Use a blow-dryer with a diffuser pushing the hair into the teeth of the diffuser attachment. If you have butter fly clips, you can leave a few of the clipped in at angel to give height or volume.
The cut is great for this messy curly hair.

Sometimes I finish off the style with a bit of medium curling iron here or there with not over doing it!
Undercut textured shag gives your the body it needs for this style.
FYI A great style and cut to deal with damaged tresses from to much coloring during the year.
Almond blond color has been quite popular for short hair.
I am experienced and like cutting short shags like this at my hair salon in West Hollywood. Make an appointment as see the difference!
