Sunday was created not just to make another shampoo, but to rethink how we care for ourselves—from the root.

Born in the subtropical climate and fast-paced rhythm of Hong Kong, Sunday is a response to the overlooked needs of modern scalps. Humidity, pollution, styling habits, and stress—these are everyday realities that affect scalp health. Instead of covering up the symptoms, we chose to understand them. Then, we built formulas to address them.

Our philosophy is simple: let your scalp breathe.

We believe healthy hair begins with a healthy scalp. That’s why every Sunday product is formulated to cleanse deeply without residue, nourish without weight, and restore the scalp’s natural balance using a thoughtful blend of science-backed ingredients and plant-based actives.

• No chemical buildup.
• No unrealistic promises.
• No unnecessary complexity.

Just honest, effective care designed to work in harmony with your body over time.We don’t believe in quick fixes.

We believe in long-term habits, gentle training, and daily rituals that support your scalp’s own ability to heal, adapt, and thrive.

When your scalp feels lighter, your hair grows better, and life flows a little more freely.

That’s what Sunday stands for—a reset, a rhythm, a reminder to care for yourself from the root.
