Can telogen effluvium cause a slight recession of the hairline?

Usually Telogen Effluvium is diffuse, with hair loss over the entire scalp.  Your hair loss (without photos) appears to be patterned, and is more likely due to male pattern hair loss.  Photos would obviously be helpful.

Telogen effluvium can cause a recession to the hairline. I suggest seeing a hair loss expert now to evaluate and go over your condition and provide you information about your best treatment options and timeline for results. There are great non-invasive options like prp/progesterone and/or hair transplantation. See an expert. Best, Dr. Emer

No, a TE would not cause a change in the hairline in the manner described, especially when it's uneven. Hairline maturation and genetic hair loss (and a range of other conditions) however would cause such a change. Please see a physician for guidance.

IF you have recession, you probably do not have telogen effluvium but rather some form of genetic hair loss.  See a specialist
