I am vitamin D deficient and I wonder why i have such paradoxical response with vitamin D3. Normally my hair is very strong and i have close to zero shedding ( although i am quite thinned out) . And every time I am trying to fix my vitamin D deficiency I get really severe shedding a week after I start supplementing 1000 iu per day which is low dose.. Any ideas why this happens ? I supplement D3 with K2
