Bis-Aminopropyl Diglycol Dimaleate

Bis-Aminopropyl Diglycol Dimaleate — technology for restoring disulfide bonds in hair

Bis-Aminopropyl Diglycol Dimaleate is a high—tech cosmetic ingredient best known as a key component of next-generation hair restoration systems. It was this compound that became the basis of the "bond-building" concept — the restoration of internal hair connections damaged by staining, lightening, thermal effects and chemical procedures.

The ingredient has become widely known thanks to the products of the Olaplex brand, but today similar molecules and technologies are used in professional systems from other manufacturers.

How Bis-Aminopropyl Diglycol Dimaleate Works

Hair consists mainly of keratin, which contains so-called disulfide bonds. They are responsible for the strength, elasticity and resistance of the hair to damage. During bleaching, coloring, perming, or regular heating, some of these bonds are destroyed.

Bis-Aminopropyl Diglycol Dimaleate is designed to interact with damaged areas of the hair structure. The molecule helps to connect and stabilize broken disulfide bonds, making hair stronger, less brittle and visually smoother.

Unlike conventional conditioning components, which mainly work on the surface of the hair, this ingredient is focused specifically on the internal structure of the web.

The main properties of the ingredient

Bis-Aminopropyl Diglycol Dimaleate is used primarily in the professional care of damaged hair and has several important effects:

• reduces hair breakage after coloring and lightening;
• helps reduce damage during chemical treatments;
• improves the strength and elasticity of hair;
• makes hair smoother and less porous.;
• promotes the preservation of hair quality with regular thermal exposure.;
• helps to reduce fluff and tangle.

The ingredient is especially in demand in the care of blonde, chemically treated and severely damaged hair.

Where it is used

Bis-Aminopropyl Diglycol Dimaleate is most commonly found in:

• bond-repair systems;
• means for recovery after lightening;
• professional salon treatments;
• intensive masks and serums;
• protective additives to dyes and lightening powders.

In many formulas, the ingredient is combined with moisturizing agents, amino acids, proteins and silicones for comprehensive hair restoration.

Features and limitations

Despite the pronounced regenerating effect, Bis-Aminopropyl Diglycol Dimaleate is not able to "revitalize" completely destroyed hair. If the structure is already severely damaged mechanically or chemically, the ingredient helps to improve the condition and reduce further destruction, but does not return the hair to its original state.

It is also important to understand that the best result is achieved when used systematically as part of a full-fledged care, especially after aggressive lightening procedures.

Which hair is suitable for

The ingredient is especially recommended for:

• bleached hair;
• dyed hair;
• damaged and brittle hair;
• hair after perming;
• dry and porous hair;
• hair that is regularly styled with hot tools.

For natural and undamaged hair, the effect may be less noticeable, since the technology is primarily focused on restoring already disrupted connections within the hair.
