Professional Acid Filler Base – Deep Fiber Restoration Hair Mask with Lactic Acid, pH 2.5–3.0, 300ml

Give your hair the ultimate strength and fiber-level repair it deserves.

The Professional Acid Filler Base is a high-performance formula designed for cold restoration of fragile, over-processed, or chemically treated hair.

With a pH of 2.5–3.0 and a high concentration of lactic acid, it works deep within the structure to reinforce disulfide bonds, rebuild internal fibers, and prevent breakage and brittleness.

This product is Step 2 in a professional three-phase filler treatment system.

For optimal results, apply Amino Acid Filler Base Architect before use, and follow with Lipid Filler Restoration of Cuticle to seal and protect the outer layer.

Important:

• This is not a standalone treatment.
• It must be used as part of a complete hair repair protocol.
• For professional use only.
• Gloves are recommended during application.
