I've notice that the Rogaine has given me severe dandruff. I have tried many types of dandruff shampoos, with little success. I've also heard that scaling skin on the scalp impedes hair re-growth. Studies have shown that the response to this drug varies a great deal from person to person. Generally, patients should not expect to see re-growth before four months of use.
New growth is shed after minoxidil use is discontinued.
Clinical studies have found that minoxidil works best for those patients who are younger, who have been losing their hair for a short time and who have less initial hair loss. The medication's effectiveness appears to be related to the activity level of hair follicles. Side effects include itching and other skin irritations on the scalp. You may want to consult a dermatologist. 882-7000 to make an appointment with a University of Missouri Health Sciences Center physician.
