This is a very easy and handy DIY if you don’t have rollers or flexy rods. I saw this DIY at Youtuber Nalia1908. The only tool you need for this style is aluminium foil. Make sure you use some (styling)products (or water, oil, sheabutter) for your hair before you put the foil in. I did it with twists.
What to do?
*For more definition, make sure you put the foil a set time. Cause I did it way too short in my hair. (lol)
