This might be a bit out of your comfort zone but why not try something new? Wrap a scarf around your head for a bohemian summer look.
It gets all buggy in this heat so why not add a few more to your life with these sweet clips from Vintage In Color on Etsy.
I foolishly bought some Bumble and Bumble beach spray for my own hair this summer but you can easily make your own by mixing 1c warm water, 1 Tbsp sea salt, 1 tsp. coconut oil, and 1 tsp of hair gel in a spray bottle.
This last one is about all I have time for most days. A messy low ponytail can be spiced up a little with a gold hair cuff. Amazon sells a ton of them here.
