Why Us
SUDTANA is a clean beauty brand specialising in hair and skincare, inspired by generations of Thai herbal traditions and refined through scientific research explored during our founder’s studies at MIT.
Our approach brings together traditional Thai herbal knowledge and MIT-backed science to create all-natural hair, skin, and body care designed to restore long-term balance.
Scalp-First, Not Trend-First
While many brands focus on surface correction, we prioritise scalp health and long-term balance. Healthy hair begins at the root, and visible skin clarity begins with a resilient barrier.
This commitment to foundational care sets us apart in a market driven by quick fixes.
Tradition Backed by Research
Our founder, Manusanun “Mew” Leelahongjudha, is a Thai MIT alumna inspired by her grandfather’s herbal practice in their Thai village. SUDTANA refines ancestral knowledge through structured formulation science without losing cultural integrity.
Farm-to-Skin Integrity
We work directly with small-scale Thai farmers to preserve ingredient traceability and botanical quality. Our small-batch production model protects ingredient quality while supporting responsible farming across Thailand.
Recognised Performance
Our root-cause philosophy has been recognised by the Clean Beauty Awards 2026 in the Hair Treatment Category, the ELLE Best of Beauty 2025 award in the Hair Care Category, the Marie Claire UK Hair Awards 2024 in the Natural Formula Category, and the Marie Claire UK Skin Awards 2021 in the Natural Formula Category.
Our formulations are also trusted within professional spa environments that value ingredient integrity and long-term results. Our collaboration with properties under Four Seasons, Rosewood, and Sheraton, among others, reflect our commitment to formulation integrity, safety, and performance in professional wellness environments.
Sustainability with Structure
Sustainability for us is operational, not decorative. We prioritise direct farmer partnerships, local sourcing within Thailand and Southeast Asia, small-batch production, and responsible packaging solutions.
