 [ Symptoms ] i received cortisone shots in my scalp for the purpose of hair growth but the shot left me with hyper pigmentation [ Disease ] hi it is hypopigmentation and can take a few months to completely get resolved if it is not aesthetic you can consult a dermatologist and get evaluated so that he can advise steroid ointments to be applied over the area but it has to be done with precaution as steroid ointments can cause skin thinning and other side effects hope this helps
