BORROWED HADN'T RESEARCHED ON THIS YET THOUGH I KNEW IT EXISTS

 How to go About Temporary Dreadlocks

I discovered how to do this while I was in high school.  I went to a catholic school, so real dreadlocks were not an option.  I wanted dreadlocks that could be worn for a day.  Here is how you do it:

You will need...
-hair straightener
-hair gel
-hair spray
-some clips or rubber bands
-flat iron protection spray (so you don't fry your hair)

Step 1. Start from the back of your head and make your way forward.  Clip/rubber band most of the top section of your hair.  Leave enough hair by the neckline to make 3 (larger dreads) to 5 (smaller dreads).

Step 2. Spray that section with that flat iron protection spray.  Divide the hair into sections.

Step 3. Twist the hair tightly and hold the end.  Iron the lock up and down a few times, going toward and against the head.

Step 4. Generously gel the lock while holding on to the tip.  Keep it as tight as you can.

Step 5. Let the gel dry for a few seconds before spraying with hair spray.  Continue until you have a head full of locks!

Remove by washing!!!

NOTE:  They will not be as tight as real dreadlocks, but will coil up individually quite nicely.
