I recently started using MDhair routine and it has been really great so far. My main goals were to improve the quality and thickness of my hair, so I was sent a 4 step treatment which includes the restore serum, customized shampoo, customized hair wellness supplements, and the collagen powder. So far, I am so pleased with the results! The routine is super easy to follow, the products smell great and my hair is starting to feel healthier and smoother. The collagen dissolves easily in my coffee, without any taste. I can't wait to see how things continue to progress in the coming weeks!
