Hairdos

By way of Fine Little Day, a list of hair-centric posts ...

Photo tutorials at A Cup of Jo - my take on the messy 'do is a braid, which the wind and my toddler then dissemble to varying degrees

Plenty of inspiration at Hair Romance - more narrative than pictorial instruction though

Messy Buns

Try this Messy Bun technique from Parisienne.

First and most important step: Make your hair dirty. “I wash my hair only once a week,” admits C. “When your hair is too clean, it won’t stay put.” After showering, she massages in either Aveda Pure Abundance Hair Potion or a homemade spray, made with one part sea salt, three parts water and a few spritzes of leave-in conditioner. “It makes my hair piece-y enough to work with,” she says.
Also of note: she recommends Rene Furterer Naturia Dry Shampoo with absorbant argilla to make it through the week between those shampoos.
