• Sodium Hyaluronate (Hyaluronic Acid): A low-weight humectant optimized to lock in essential moisture without forming a heavy film on fine follicles.
• Coco-Glucoside: A very mild, coconut-derived surfactant that gently clears excess sebum and styling residue while preserving the natural scalp barrier.

Suitable For

• Hair Types: Specifically engineered for fine hair textures across all styles, including straight, wavy, curly, and coily hair.

How to Use

1. Saturate: Wet your hair completely with warm water.
2. Emulsify: Dispense a very small amount of this highly concentrated formula (a little goes a long way) into your hands and rub your palms together to create an active lather.
3. Massage: Focus the ultra-light lather directly onto your scalp and roots to lift away oil, then gently work it down through the mid-lengths and ends.
4. Rinse & Follow: Rinse thoroughly with water. Gentle enough to be used as your daily shampoo or on every designated wash day.
