How do you tell if you have DUPA vs Diffused thinning MPB? I’ve searched online, and haven’t really found substantial answers. I have diffused thinning across the top of my scalp, with it being noticeably thinner at my crown. Some hairline recession as well. I got a scalp biopsy done and derm said MPB, but I […]

I have diffuse thinning and believe that it is DUPA. Is it more difficult to treat? Make sure that you have DUPA, just don’t assume you have it. The unpatterned thinning extends to the side and back of the head which is usually protected against genetic balding. It is much more resistant to treatment. To […]
Note that his donor area hair is not high in the back of his head, and much of the donor area we can see is see-through. This man, fortunately, never had a hair transplant for it would make his situation worse and it would produce significant scars, adding to his problem. [If you have any […]
Many men have written to me to ask me if they had Diffuse Unpatterned Alopecia (DUPA), which I defined in the literature with Dr. Bob Bernstein in 1996. This is a “female type of pattern” where the hair in the donor area has significant miniaturized hairs. In men, it is also called Senile Alopecia when […]
As you suggested, this is a photo using a hand microscope of the donor area. What do you think? My rule for diagnosing DUPA is to count the miniaturized hairs from the back of the head. If they exceed 20%, as yours does, then it is DUPA. You have some hair that is being lost […]
A 30-year-old man contacted me for surgery. As usual, I had him purchase a hand microscope and a micrometer. We went on Zoom, where he took control of his hand microscope. First, we used the micrometer. He measured his donor hairs (about 20 of them), and they ranged from 30 microns to 91 microns, averaging […]
You know how with senile alopecia or DUPA, the hairs miniaturize but don’t (usually anyways) actually shrink to the point where they fall out and stop growing altogether? They miniaturize to a certain extent but then stabilize in a miniaturized state and are still retained (hence why you don’t see people with DUPA develop totally […]
I am scheduled for an upcoming hair transplant, and I am worried about having Diffuse Unpatterned Alopecia (DUPA). The surgeon didn’t understand when I asked him about DUPA in my donor area, and I don’t want to go forward if I have DUPA. Please help me with the diagnosis. Here are four pictures from my […]
Are Dupa (Diffuse Unpatterned Alopecia) and Age related thinning the same condition, just that the former name is applied if it develops in a young person whereas the latter name is applied when it develops in a person of advanced age? No, these are not the same. DUPA usually has miniaturization well over 50%, if […]
I am a 21 year old male that has noticed my hair appears to be thinning on the back and sides after I buzzed it. This was not visible whilst I had longer hair. Please see the attached image of my donor area under a microscope. This is a difficult call. What I am seeing is a drop […]
This astute 23-year-old male examined his donor area through a hand microscope purchased from Amazon after reading some advice I gave on Reddit. He was suspicious about having DUPA based on his view of his donor area, so he sent them on to me for an opinion. Both Dr. Bernstein and I believe that this […]
I fear I may have developed DUPA. My sides and back have become transparent and I am approaching an NW7. I have added oral fin, oral min, and topical pyrilutamide which I believe has helped and the oral min has regrown some hair and increased thickness a bit. But the density is still poor. I […]
With Dupa and Age related thinning, does every single follicle on the scalp miniaturize? And do the miniaturized follicles in these conditions eventually miniaturize to the point where they fall out and stop growing altogether like in AGA, resulting in a totally bald scalp (including the donor area)? Or do they miniaturize just to an […]
DUPA (Diffise UnPatterned Alopecia) is fairly uncommon. The diagnosis is always made by examining the hair in the back of the head with a hand microscope (Trichoscope). Here is an example of what it looks like: https://baldingblog.com/do-i-have-dupa-photo/
I have dupa I need to know if hair fibres work well for hiding side and back hair spots I have thin hair there If you really have DUPA, then Scalp Micropigmentation (SMP) is the thing to do aside from treating the disease with finasteride.
