Strengthening Repair Mask

La Biosthetique Strengthening Repair Mask is a high-performance, professional salon treatment specifically engineered to provide deep structural repair and weightless volume for thin, fragile, or damaged hair strands.

Balancing deep care with lightweight body, it prevents fine hair from going limp.

Best for:

• Thin, fragile, or damaged hair strands;
• Those looking for deep structural repair with weightless volume;
• Anyone with fine hair that has undergone chemical services or heavy thermal styling.

Key Product Pros:

• Unlike standard rich repair masks, its gel-cream hybrid formulation leaves fine hair airy, bouncy, and full of kinetic movement;
• Actively plumps the hair shaft, providing noticeable root lift and overall body;
• Rebuilds fragile disulfide bonds and internal networks, fortifying strands against split ends;
• The botanical protein coat behaves like a natural defense barrier against blow-drying and heat-styling friction;
• Smooths out the hair cuticles instantly, minimizing messy flyaways and cutting down brushing breakage;
• Imbues the hair with a professional, glossy, and light-reflecting shine alongside a signature sophisticated fragrance.

Active Ingredients:

• Tahitian Microalgae Extract acts as a powerful volume booster that revitalizes the hair structure right from the roots and drastically minimizes breakage;
• Hydrolyzed Rice and Soy Proteins penetrate porous areas within the cortex to repair structural damage, smooth out rough cuticles, and seal moisture inside;
• Carrageenan Moss and Sugar Kelp Extracts provide a boost of mineral-rich, lightweight hydration while acting as a natural shield against thermal styling damage;
• Natural Humectants infuse moisture into the core of the strand, reducing static electricity and flyaways while enhancing elasticity.

About Volume Line:

• The line is a premium collection designed for individuals with fine, limp, or structurally weakened hair.
• The entire line aims to thicken the hair diameter, reinforce fiber resilience, and provide a lifting effect from the roots without leaving oily residues.
• For optimal results, experts recommend pairing this mask with the Strengthening Shampoo.

Wash your hair with a suitable shampoo, ideally from the Volume line, and gently squeeze or towel-dry excess water.

Evenly distribute an appropriate amount of the mask through the mid-lengths and ends, working it right up to the root area if needed.

Leave the mask on for 10 minutes to allow the micronutrients to fully bind to the hair fiber.

Rinse thoroughly with lukewarm water. Use weekly for continuous structural maintenance.
