Causes, diagnosis and treatment of Diffused Patterned Alopecia (DPA)

Diffused Patterned Alopecia (DPA) is a type of androgenic alopecia or genetic hair loss. Unlike typical male pattern and female pattern hair loss Diffused Patterned Alopecia does not follow the Norwood scale or Ludwig scale. In this article we will discuss how Diffused Patterned Alopecia (DPA) is caused, diagnosed and treated.

Causes: Diffused Patterned Alopecia (DPA) is a type of hereditary hair loss commonly referred as androgenic alopecia or genetic hair loss. Diffused Patterned Alopecia (DPA) can affect both men and women, however it is more common amongst men. In some individuals their follicles are genetically vulnerable to balding. Over time, these genetically vulnerable follicles are attacked by the hormone known as Dihydrotestosterone (DHT). This hormone binds with the receptor sites of these susceptible follicles and cause the hair follicles to shrink overtime until they no longer grow.

Diagnosis: Diffused Patterned Alopecia (DPA) can be difficult to diagnose especially in its early stages and is often misdiagnosed as Diffused Unpatterned Alopecia (DUPA). While both conditions are characterized as as diffused thinning, Diffused Unpatterned Alopecia (DUPA) sufferers lack the stable permanent zone neccessary for hair restoration. Dermatologists and hair restoration surgeons are able to diagnose Diffused Patterned Alopecia (DPA) by comparing the top, sides, and back of the scalp by using high magnification instruments that can detect miniaturized follicles. If the top of the scalp contains miniaturiztion and the sides and back of the scalp do not, then the surgeon is able to ascertain whether or not the patient is suffering from Diffused Patterned Alopecia (DPA) or Diffused Unpatterned Alopecia (DUPA).

Treatment: Diffused Patterned Alopecia (DPA) responds well to medical hair loss treatments like Propecia (finasteride) and Rogaine (minoxidil) both medications are approved by the FDA as genetic hair loss treatments. Both hair loss drugs work synergistically together and both can stop the progression of hair loss and even regrow hair in some patients.Hair tranplant surgery is also an option for many men and even women with Diffused Pattered Alopecia or DPA. 


It is crucial that men and women suffering from androgenic alopecia or genetic hair loss consult with a skilled and experienced hair restoration surgeon  to properly diagnose their hair loss. It is critical to differentiate between Diffused Patterned Alopecia (DPA) and Diffused Unpatterned Alopecia (DUPA) because DPA patients are candidates for hair restoration surgery  while DUPA patients are generally poor candidates for hair transplantation due to the  lack of a stable permanent donor zone.
