Yep, I know all about bathroom mirrors and outdoors, and how that can affect things. My hair can look hilariously scalpy when under direct sunlight.
It looks thin under direct lighting and if combed up, but looks 100% fine in normal lighting, or even in harsh light when combed slightly forward.
You're right though, time to start treatments - Looking forward to seeing what they can do!
I've been applying Dr Lee's 5% minoxidil once per day (at night), but I am thinking that propecia may be a better bet, or possibly both, although I am not sure minoxidil is really necessary at this stage.
Just ordered some revivogen too, which definitely works I would say, judging from their trials, and some of the user experiences here. Two DHT combatants should help I reckon.
