Q: Can stress produce diffuse unpatterned hair loss (DUPA), or was it bound to happen anyway? — D.D., Park Slope, Brooklyn

A: Both DPA (diffuse patterned hair loss) and DUPA (diffuse unpatterned hair loss) are genetic conditions, unrelated to stress and would have happened anyway. These types of hair loss are characterized by a high percentage of mininiaturized hair in broad areas of the scalp. See the Classification of Hair Loss in Men and Classification of Hair Loss in Women pages on the Bernstein Medical – Center for Hair Restoration website for more information on this topic.

In contrast, stress generally presents as increased hair shedding, a reversible condition referred to as telogen effluvium. It is called this because the normal growing hair is shifted to a resting (telogen) phase before it temporarily falls out. Increased miniaturization is not associated with telogen effluvium.

Q: I’m currently 24 years old. Ever since turning 20, my hair on top began to thin little by little. I have noticeable thinning on the top part of my scalp and on my crown, but have no recession at the temples. My hairline looks amazingly young and hair on the donor areas seems quite thick. Am I in the early stages of male patterned baldness? I cannot place myself in the Norwood scale since my thinning doesn’t seem to follow the classic pattern. I just started on Propecia. Should I be considering a hair transplant? — B.R., Landover, MD

A: From the description, it sounds like you have typical Diffuse Patterned Hair Loss or Diffuse Patterned Alopecia (DPA). In this condition, the top of the scalp thins evenly, the donor area remains stable, and the hairline is preserved for a considerable period of time. Please see: Classification of Hair Loss in Men for more information.

Propecia would be the best treatment at the outset. When the hair loss becomes more significant, patients with DPA are generally good candidates for surgical hair restoration. It is important, however, that your donor area is checked for miniaturization to be sure that it is stable before a hair transplant is considered.
