Japanese Water Gloss Mirror Straight Hair Treatment What is the difference between Paimore Straight Treatment and LV PRO Water Gloss Mirror Smooth Straight Treatment? Both Paimore Straight Treatment and LV Pro Water Gloss Mirror Smooth Straight Treatment are modern non-damaging or low-damage straightening techniques, offering a more natural and glossy result compared to traditional ionic perms. Paimore focuses on patented restoration technology, with strong structural reconstruction and a durability of about 6–9 months. LV Pro, on the other hand, uses a mildly acidic "medical-grade" formula, providing intensive repair and an ultimate water-gloss mirror finish, making it suitable for severely damaged hair after bleaching or dyeing.
