LvPro 01 Hard 1000ml

Gentle Yet Powerful Weakly Acidic Straightening for Stronger Texture Control

A professional acid straightening cream that combines hair-friendly pH with enhanced reducing power to address a wider range of curls and frizz.

LvPro Acid Fiber Straight is formulated around the concept of minimising damage by eliminating alkaline agents, which are a primary cause of hair stress. Working in a weakly acidic range close to hair’s isoelectric point, it significantly reduces chemical load and unpleasant perm odour while delivering reliable straightening performance.

Unlike conventional alkaline straighteners, this system can effectively smooth highly damaged or bleached hair, which are often difficult to manage, while maintaining softness, shine, and a natural finish.

LvPro Acid Fiber Straight 01 Hard

Building on the core performance of LvPro 01 Natural, the Hard version adds a low-odour cysteamine as an auxiliary reducing agent. This enhances straightening strength while keeping odour minimal, allowing flexible control over stronger curls, resistant textures, and retouch applications.

Product Features

■ CTG (Cysteamine Thioglycolate) as the Main Reducing Agent
CTG is a next-generation reducing agent developed for damaged hair. It maintains reducing power even below the isoelectric point (pH 4.5–5.5) and helps protect hair integrity during heat processing. It also significantly suppresses residual perm odour.

■ Four Functional Care Ingredients

Fiberhance (Hair-Strengthening Component: Gluconic Acid / Gluconamide)
A glucose-derived strengthening ingredient designed to act within the hair cortex. By bonding with keratin, it reinforces keratin fibres from the inside, improving strength, elasticity, and body.

Levulinic Acid
When activated by heat, it enhances shine and softness while improving overall hair texture. It is a mild, high-safety acid with no residual odour.
LvPro is not an acid heat treatment.

Nano-Elcalactone (Heat-Responsive Inner Treatment Ingredient)
Penetrated elcalactone reacts with amino acids in hair proteins when heat is applied, forming bonds that significantly improve shine and tactile smoothness.

Nano Ceramide Complex
Five types of ceramides and 18-MEA derivatives are nano-encapsulated for efficient delivery to damaged areas, helping restore moisture and leave hair smooth and supple like healthy hair.

■ LvPro Booster G48 for Additional Power (Optional)
When extra straightening strength is required, LvPro Booster G48 can be added to increase reducing power while maintaining a hair-friendly pH. Suitable for strong curls and virgin root retouching.
※ Use up to a maximum of 10% relative to the first agent.
※ Mix only the amount needed for immediate use; never return leftover product to the container.

■ About GMT
GMT is a German-developed reducing agent designed for use in the weakly acidic range (hair’s isoelectric point). Its amphiphilic nature allows it to penetrate efficiently into hair, ensuring uniform internal action.
