Yup!!! no matter what people say. these are absolutely related.
People with bigger foreheads especially lose more hair and also are often blessed(should I say cursed) with very thin hair to start with and appear more "Aged" If I can use the word. And unfortunately, these are not even good candidates for a HT and more tragically, I am one of them.
there might be people who have bigger foreheads but also have the hair to account for it, but they are an exception rather than the rule.
tragic it may sound but that's the harsh reality.
