Sometimes I don't even wash it every other day... shh don't tell anyone.
But lately I've been tired of my typical bun for my 2nd/3rd day hair, so I decided to switch it up with some heidi braids. Remarkably, they were are easier than they look.
Separate your hair into two equal parts and secure loosely with a band.
(optional: tease each side at the crown to create volume. I also tease part of the lower hair before I braid as well.)
Braid the right side starting at your ear. Braid "up" -- as you braid, move the braid higher (see above). This will make it easier to pin to the side. Secure with a clear elastic.
Pull the braid straight over your head and pin at least three times: one near your ear, once in the middle and one at the end of the braid. You can tuck the pins into the braid to make them less visible.
Repeat on the other side, braiding the left side up at an angle and then pinning over the right side. Tuck the ends of each braid underneath each other.
Tada! Easy-peasy heidi braids.
And don't worry if it isn't perfect; it looks better a little mussed.
