Hello!
In TCM the Kidneys are said to "manifest in the head hair". The Lungs "Dominate the skin and body hair".
The quality of the Blood can be seen in the dryness and brittleness of the skin, nails and hair, as one of the functions of Blood is to keep things moist.
In this way the quality of someone's hair can give information about their Kidneys, Lungs and Blood. e.g. someone who is thinning or balding with dry hair may have Kidney and Blood deficiency. Someone with a full head of brittle hair may have good Kidneys but poorer Blood etc..

HTH!
