I have had microneedling on my back to remove sun damage. I am 2 treatments in and already seeing a difference. I am squeamish at the sight of needles and I have had hair filler by roxanne. She took her time injecting the product in my scalp and again 2 treatments in my hair is fuller. It has more bounce and the patchy areas are less visible and seeing new hair growth. I am pleased with my results and she is very skilled and her technique with injectables/needles is superb.
