Frequently Asked Questions
About YUSOU
YUSOU is a Thai-founded haircare brand created by EMMÉ LAB.
Guided by our mission to create beauty rituals that strengthen rather than strip, we develop thoughtful formulas designed for real life—helping care for your hair while respecting your colour. Every detail is shaped by Calm Confidence, Thoughtful Innovation, and Clean Intention.
YUSOU is a name inspired by the languages and philosophies of East Asia.
Rather than being a direct translation of a single word, it was intentionally created to reflect values of grace, balance, craftsmanship, and quiet excellence.
To us, YUSOU represents The Art of Gentle Victory—the belief that meaningful beauty is achieved through care, intention, and consistency.
YUSOU is proudly created in Thailand.
Our products are thoughtfully developed to meet international cosmetic standards, combining carefully selected ingredients from around the world with formulations designed for real-life lifestyles and climates.
Every product reflects our commitment to Calm Confidence, Thoughtful Innovation, and Clean Intention.
YUSOU does not test its finished products on animals. We are committed to responsible product development and believe in being transparent about our practices as the brand evolves.
Yes. Every YUSOU formula is thoughtfully developed with colour-treated hair in mind.
Our products help care for coloured, bleached, highlighted, balayaged, and chemically processed hair by supporting softness, shine, and long-lasting colour. Designed for everyday life, they help protect your hair from daily stressors such as washing, heat, humidity, and UV exposure while maintaining healthy-looking hair.
Yes. YUSOU products are thoughtfully formulated for regular use, including daily use when needed.
Unlike treatments designed for occasional use, our formulas take a gentle, balanced approach to colour care—helping maintain softness, shine, and colour vibrancy while respecting your hair and scalp.
For the Violet Veil Blonde Toning Shampoo, the ideal frequency may vary depending on your hair colour, tone, and desired result. You can adjust usage as needed to maintain your preferred look.
YUSOU products are thoughtfully formulated with a gentle, balanced approach for everyday use.
However, every scalp is unique. If you have a particularly sensitive scalp, known allergies, or specific skin concerns, we recommend reviewing the ingredient list carefully and performing a patch test before first use. If irritation occurs, discontinue use and consult a healthcare professional if needed.
Products
Yes. YUSOU products are thoughtfully formulated for all hair types and textures, including straight, wavy, curly, and coily hair.

Yes. YUSOU products are suitable for most types of hair extensions.
This includes clip-ins, tape-ins, wefts, and other professionally installed extensions. To help maintain the longevity of your extensions, avoid applying conditioner directly to the attachment points or adhesive bonds, and always follow the aftercare advice provided by your extension specialist.
The full ingredient list is available on each product page and on the product packaging.
If you have known allergies or ingredient sensitivities, we recommend reviewing the ingredient list carefully before use. If you have any questions about a specific ingredient, our Customer Care team is always happy to help.
Our products have a shelf life of 24 months when unopened. Once opened, we recommend using them within 12 months.
We do not recommend using YUSOU products after their expiration date, as we can only ensure the quality, safety, and performance of products used within their recommended lifespan.
