The Lebel IAU Cell Care system is a professional 5-step hair treatment designed to build and retain moisture using the concept of bound water (結合水). This innovative approach helps deeply hydrate both the scalp and hair while maintaining softness from roots to ends.

Unlike treatments that only add moisture temporarily, this system strengthens the hair’s internal moisture-retaining ability for long-lasting hydration and manageability. The secret lies in its "moisture structure" technology, which enhances the hair’s ability to bind water and maintain elasticity.

What is Bound Water?
Bound water is essential for maintaining lasting hydration. It’s not just about adding water to the hair but enhancing its ability to hold and retain moisture within. This treatment system boosts both scalp and hair hydration power from the inside.

Step-by-Step System:

【Step 1】IAU Cell Care 1 – Scalp & Hair Moisture Base

Scalp: Replenishes hydration in the stratum corneum, adds elasticity, and protects the scalp barrier.
Hair: Penetrates with moisturizing agents to protect against damage and promote water retention.

【Step 2】IAU Cell Care 2 – Fiber Restoration

Introduces fiber-repair ingredients to reinforce the internal structure of damaged hair.

【Step 3】IAU Cell Care 3S SILKY / 3M MELT – Lipid Infusion

3S SILKY: Lightweight, silky finish.
3M MELT: Rich, deeply moisturizing finish.
Both contain lipid ingredients that connect water and protein inside the hair for smoothness and flexibility.

【Step 4】IAU Cell Care 4 – Hydration Lock Oil
