Dr. Clara Santos is one of the best known aesthetic dermatologists in the world. She has the largest series (more than 10 years) of successful results in hair restoration treatments using Carboxi therapy and other Mesotherapy techniques in the world. She practices in Sao Paulo, Brazil, and I had the privilege of participating in her training course at her very busy clinic and to learn from her first hand in February 2011. She practices a wide array of dermatologic aesthetic techniques, including peels and body sculpting. However, my primary reason for visiting her was to gain first-hand knowledge on Carboxi and Mesotherapy treatments for hair restoration from the world’s most experienced practitioner in this area.
