The Alma TED hair restoration treatment uses a handpiece that sends sound waves and light air pressure into your scalp. This combination of sound waves and air will work in harmony to enhance circulation and promote hair growth. You should not notice any discomfort during the treatment; in fact, many patients report the treatment to be a relaxing experience. The number of sessions you need for optimal results will be determined during your initial consultation; however, you may notice visible changes in as few as three treatments.
