Hi my question is about the HairDX test. If male pattern baldness can be inherited from either side of the family, is the Hair DX test only about 52 percent accurate since it tests the X chromosome only? And is it even less accurate in regards to actual hair loss because of the complex gene expression?
Men have one X chromosome and one Y chromosome so the impact for the test on a man’s only X chromosome is clearly from one parent or the other. The overall predictability is only about 70% and possibly the cause of the difference between 70% and 100% are the other factors associated with gene expression and possibly other genes not tested.

One parent or the other? Men can only pass on the Y chromosome to their sons except in those rare cases which would probably preclude hair loss altogether(XXY, XXYY).
Hi, im interested in taking the HairDX genetic test. Is it correct that this test only tests the x chromosome?
Does this mean this test is not very helpful to me as there is no genetic hair loss from my mothers side, even my 95 year old grandfather has a head full of hair, with no receeding hair line. However, everyone on my fathers side is bald. Will the HairDX test not use that in the determination? or would you say its still useful?
