How to use

All dosage guidelines below refer to medium-length hair. Adjust amount depending on hair length and thickness.

① Step 1 — IAU Cell Care 1

Apply 10 pumps (approx. 30 mL) directly to the scalp and hair after shampooing and towel drying. Gently massage from scalp to ends. This step helps refresh the scalp, remove residue, and boost moisture absorption while delivering anti-aging care. Rinse thoroughly.

② Step 2 — IAU Cell Care 2

Apply 18 pumps (approx. 6 mL) focusing on mid-lengths and ends. Work into the hair with fingers. This step infuses the cortex with hydrolyzed proteins and improves the permeability of active ingredients. Do not rinse.

③ Step 3 — IAU Cell Care 3S & 3M

Use either 3S (for fine/soft hair) or 3M (for thick/coarse hair). Apply 6 pumps (approx. 18 mL), spread evenly on hair length. Massage thoroughly and leave for a few minutes. Do not rinse. Proceed directly to Step 4.

④ Step 4 — IAU Cell Care 4

Apply 6 pumps (approx. 18 mL) to seal in moisture and smooth the cuticle. Spread from mid-length to ends, massage in, leave briefly, and rinse thoroughly.

⑤ Step 5 — IAU Cell Care 5S & 5M

These are take-home masks for weekly use. Each 40 mL tube provides approx. 4 applications (about 10 mL per use). Apply after shampooing, spread from mid-length to ends, leave for 3–5 minutes, then rinse well.

Avoid contact with eyes and do not use on broken or irritated skin.
