Hair

Can we talk about something frivolous for a minute? I realize in the grand scheme of things my hair is not exactly a pressing matter but I need hair help. I need suggestions. I need advice. I need someone to tell me what to do.  

This is my hair: 

This is also my grumpy morning face.  

My hair is very fine and is also thinning thanks to kids and cancer and wonky hormones. I haven't had it cut in 8ish? months. The last time I had it coloured was April of 2016. 

I have a hair appointment scheduled for Saturday. Normally I would just show up and my amazing stylist would tell me what she was going to do, she'd do it, I'd love it, end of story. But my amazing stylist has left the hair world (SADNESS) and I'm going to someone new. Cue panic.  

I had virgin hair when I started seeing my old stylist so she was able to do my foils using "high lift" (I don't know anything about hair but this excited her). Do I continue highlighting my hair? Do I go darker? Do I chop it all off and start new? Tell me what to do. 

I wear my hair up in a messy bun pretty much every day. I have a lot of postpartum regrowth creating a fuzzy halo around my face and nape of my neck. The regrowth is about 50% grey because bodies are the worst. My hair is wavy and gets curlier the shorter it gets. The picture above is after I blow dried it without product. If I let my hair air dry it's a frizzy, wavy mess. 

I am not adverse to longer, sideswept bangs but my hair can't do blunt bangs. I cannot do a lot of layers or the frizz gets out of control. I am toying with attempting the Curly Girl Method to see what happens (but I'm also so very tired so probably I'll attempt it in 2019).

So! What should I do with this mop? Bonus points for links and pictures.
