I've been on treatments for about 2-3 months now, and I also noticed my hair get much darker (which I prefer). I think it definitely looks like you've gotten some thickening man, looks great! Keep it up! I've also noticed my eye lashes have gotten longer unless I'm just imagining it? Have you noticed the eye lashes too or ?
Different angles, different lighting, different...hair color? hard to tell. But the temples look somewhat thicker.
I can definitely see thickening, especially in the crown... I would attribute this entirely to the minoxidil/keto. What's with the LLLT brother? It's just a waste of time! Stick with what you are doing and DON'T add anything for a while. Be grateful you are responding.
