I was also scrolling about Yoga because I heard people said it will be very helpful to increase health. And I have a back pain to start with. Coincidentally I found this article saying Yoga also can help with hair loss. But not to the optimum. Yoga somehow can help with blood circulation at our head, by consistently practice headstand yoga.

This is the first I've heard of it, but it looks interesting. I don't know about yoga, but it helped me to change my diet and stop eating sugar. And I will try yoga, sounds interesting.
