Blood tests for Men and Women with Genetic Hair Loss: Is Measuring DHT Necessary?

New study shows Measuring DHT not Helpful

Androgenetic alopecia (AGA) is one of the most common types of hair loss in both men and women. In men, it is known as male pattern balding and in women it is known as female pattern hair loss.

The exact reason for genetic hair loss remains to be worked out but it is thought that in those affected genetic factors make the hair follicles more sensitive to the hormone dihydrotestosterone (DHT). Such sensitivity causes those hair follicles to get skinnier and skinnier with time - a phenomenon which is called 'miniaturization'


Measuring DHT : A good idea or not?

If DHT is so important in the development of genetic hair loss, a common question is whether doing a blood test for DHT has any value in the evaluation of androgenetic alopecia. 

A recent research study was designed to evaluate the benefit of measuring DHT blood levels in men and women with androgenetic alopecia. The study comprised 49 individuals, including 9 men and 19 women with androgenetic alopecia. The control group consisted of 17 healthy women and 4 men without hair loss.


Study Results: No Benefit of Measuring DHT

All in all, increased serum concentrations of DHT were observed in both patients with androgenetic alopecia and in those without. More importantly, the differences in mean values of DHT were not significant according to two groups and increased serum concentrations of DHT were not correlated more severe hair loss.



Although DHT plays an important role in the various steps that lead to androgenetic alopecia, measuring DHT blood levels are not useful for most patients.
