Body changes

I’m seeing some odd body changes in the last few weeks. I’ve been doing a VLCD diet to try to reduce total fat mass. It involves calorie/protein cycling and its brought my fat down but also robbed some muscle (too much actually). I’m coming off the diet but I’ve seen some strange sides. Aside from being smaller and a bit more cut my ‘hair’ has changed. I know this sounds odd but my hair is becoming thicker and almost curly (at least wavy). Any explanation for this?
