Convenience of a Nearby Mole
In the early stages monitoring hair regrowth can be challenging - especially when the degree of hair regrowth is not enough to be noticeable by the patient.
In these situations it can be very helpful to compare the changes that have occurred at a fixed location of the scalp. During clinical trials, a small circular dot is often tattooed on the scalp so that the clinician can compare that exact same spot over time.
In daily practice we don't tattoo the scalp. However, if a patient has a mole, pigmented spot, or blood vessel this can be used as an easy frame of reference to compare how hair density in the area changes over time.
