1. We start by giving substance to the hair with a salt water styling spray (our editorial favorites are in this selection). When you have very thick hair, you do it in two parts:you tie the top and you only spray the lower part of the hair.
2. We pass a stroke of the hair dryer and then brush. Then we part her hair in four and braid quickly.
3. After applying hairspray to each braid, take your hair straightener and apply light pressure throughout the braids.
4. Finally, remove the rubber bands and untangle roughly. For a little final touch, we add a little hairspray.
And There you go ! You have mermaid hair!
