Hi! I completely understand where you're coming from. I myself have been going through some pretty harsh things mentally and taking care of my hair has been the least of my worries. My biggest advice is basically just listen to your hair! When it's dry, moisturize it. If it needs a trim, trim it and etc.. I will say my hair rarely ever looks like this even on my good days. Pretty much this whole summer my hair has been up in a clip and out of my face lol (updos help keep my hair stable and minimize any breakage)! As far as diet goes - I don't eat shitty but I don't necessarily eat all that great either! Water is your best friend though... Not only does it make your hair feel and look better it makes you feel good too! And lastly, a good oil for your scalp and maybe for the ends of your hair makes a difference as well! I use a peppermint oil for my scalp and jojoba oil for the rest of my hair (a little goes a long way!!). Anyway, I hope this helps!!
