I'm using her products since I was a child. Her oils "S" and "N" are popular for hydration and hair fall. Another classic is the Mirtha's brush. In Puerto Rico is difficult to buy for normal hair ("herbal" shampoo, regular conditioner, "N" oil, and "wave set" for styling). Sometimes I have to buy it by online. The famous motto was: Whatever your beauty problem, Mirtha's has the answer.
