Rooted in traditional Thai herbal lore, SUDTANA takes a modern approach to ancient remedies and rituals for naturally healthy, radiant hair and skin. Our Nourishing Hair Mask Oil & Scalp Revival Treatment Set is handcrafted with natural herbs that have not only been used in traditional Thai medicine for centuries, but have also been academically and scientifically verified. Our formula is based on the time-tested recipes handed down by our Founder's late grandfather. Recipes our Founder took with her to MIT to enhance their potency while staying true to their traditional roots. After two years of scientific tests and trials, what resulted are harmonised blends of concentrated herbal oils, specially balanced in calculated ratios to enhance their potency, purity, safety and performance without a single drop of chemical present.
