I was going through an eating disorder due to depression about a year and a half ago, and I lost a lot of weight because of it. I believe my unhealthy weight caused a telogen effluvium episode about a year ago. My scalp got extremely itchy all of a sudden and I was shedding a lot of hair. This shampoo with ketoconazole called lemerie or something on amazon helped a lot with the itching. Unfortunately with men, I have read that telogen effluvium can kick start male pattern baldness. To explain this better, when you shed the hairs with telogen effluvium it is just like skipping ahead 5-6 years or whatever the life span of the hair was. If the hair would have been affected by male pattern baldness 5-6 years down the road, that is why telogen effluvium can turn out the way it does for some males. I think telogen effluvium mostly affected my temples though. All of my hair felt slightly more thin when first going through the shed, but now a year later my hair is about 8 inches long all around and mainly my temples have receded a little. The main balding pattern on my dad's side is receded temples but not much loss on the back and crown. It looks like your hair has thinned on the whole top of your head. Is anyone in your family a Norwood 6, look at the balding patterns and see if anyone's matches where telogen effluvium has affected your hair.
