Excessive hair loss is called Khalitya in the classical Ayurvedic texts. Khalitya is diagnosed as an imbalance in all the tridoshas - Vata, Pitta and Kapha.
Let's take Kapha; just as an example. Kapha manages the nutrients on your scalp. If Kapha is too low, then there isn't enough nutrition reaching the hair roots. Like a clogged pipe. But if Kapha is too high, then there is congestion. And that prevents nutrition from being absorbed by the hair roots. It repels water like a non-stick pan or a lotus leaf.
So Kapha balance is crucial – in fact, dosha imbalances effectively starve your hair roots of nourishment. Balancing the scalp enables the nutrition to easily reach the follicles and also get absorbed.
Ayurveda is not just a bunch of herbs - it is about balance. Modern medicine calls this concept of balance, homeostasis.
