Is Kenalog related menstrual cycle disruption and hair shedding/loss?

If you just consider kenalog by itself, it can be a cause of hair loss.  In general, it may take over a year before you see hair regrowth.  However, there may be other reasons for hair loss that you are not aware of.

Kenalog injections can cause irregular periods in a small proportion of women. It takes about 2-3 months for normal periods to resume, rarely a bit longer.REFERENCE FOR INTERESTMens JM et al. Disturbance of the menstrual pattern after

Without knowing more about your history and being able to examine you, I can't tell you if your hair loss will reverse if you stop the steroid injections
