Hi hun, its good to hear that you are feeling much better today. I think it just takes abit of time for your body to adjust to the diet.
I wouldnt worry about the hairloss. When i first did CD, i started to experience abit of hairloss once i lost about 3 stones. It wasnt much and its all grown back now.
Some people have experienced hair loss when they start moving up the steps and when they return to eating but it shouldnt last long and it should grow back soon after. Its all part of the cylcle that your hair grows through.
But if you're really concerned, try doing a search for hairloss on here and you should find alot of information about what others experienced and how they went about looking after there hair. I know i posted something a while back about a shampoo bar that i was using from Lush to help make my hair thicker and i would highley reccommend it.
