Typical volumising products use hair-dehydrating ingredients (alcohol, salt and drying resins) to dry out and force open hair’s protective, outer cuticle layer. When the cuticles are roughed up and raised, hair strands can’t lay flat, creating the effect of fluffed-up, full-volume hair. However! opening the cuticle is very damaging, and leads to dehydration, frizz, brittleness. Xtra Large uses totally new volumizing technology: a weightless yet bulky polymer blend(fortified with strand-strengthening BAMBOO) that mimics a raised outer cuticle layer but leaves hair’s essential cuticle layer smooth, intact, and hydrated. The result? Instant voluptuous, sexy “naked” volume, body, guts and grip without compromising hair health.
