Lebel IAU Serum Mask

Lebel IAU Serum Mask is a concentrated weekly treatment from the IAU Serum line, designed for dry, thinned, frizzy or chemically processed hair that needs deep smoothing and a visible reset along the lengths. The aroma-rich formula sinks into the cortex, helps the cuticle sit flatter, and leaves hair feeling elastic, glossy and easier to control.

It sits as the once-a-week intensive step in a Lebel IAU Serum routine, applied through the lengths after shampoo and rinsed out before the regular conditioner or leave-in; for severely damaged hair, pair with an IAU activator serum for an added boost. Cell Membrane Complex penetrates deep into the cortex to help replenish the inner lipid structure that heat, colour and daily wear gradually wash out, while Inca-Inchi seed oil and karite (shea) oil, the IAU Serum line's hero combination, coat the strand in a thin omega-rich film that controls surface frizz from the inside out. The Nanogel hydration system holds moisture in the shaft so the smoothing effect lasts longer than a film alone would give, leaving the cuticle visibly smoother — and because the effect builds with each application, results become more pronounced with regular weekly use rather than after a single treatment.
