32 year-old man with dupa hair loss. I did DHI hair transplant, could the transplant be harmful to the existing hair?

Personalized medical advice on the Internet without a good history and examination is inaccurate and may lead to confusion. It is best to speak with a expert who can help determine if your condition is DUPA.

it seems the dhi method does not include a scalp analysis. Please go back to your surgeon and ask why they proceeded to surgery when you had a contraindication for a hair transplant. 

Diffuse Unpatterned Alopecia (DUPA) is an uncommon form of male hair loss where there is thinning of the hair throughout the scalp. It can co-exist with male pattern hair loss. Most reputable hair transplant surgeons would advise patients with DUPA not to have a hair transplant as there is no scalp 'safe zone' from which to harvest donor hair and the generalised thinning can be progressive.
