Is ridging in the forehead is a new sign of FFA?

Frontal fibrosing alopecia or FFA causes hair loss along the frontal hairline and temples and sometimes even extends around the back of the scalp as well. Many patients experience eyebrow, eyelash loss and even body hair loss. Treatments are urgently needed to help stop the condition before hair transplants can be considered. 

Researchers from Spain recently reported a new finding that we should all be on the lookout for - depression of the skin overlying the frontal vein (which is a vein that can often be seen in the middle of the forehead). The researchers reported 11 women who had a depression or ridge in the skin overlying the frontal vein and propose that this too is a feature of frontal fibrosing alopecia.
