* Penetrating the hair shaft: Restructurants contain ingredients that can enter the hair's cortex, the inner layer responsible for strength and elasticity.
* Rebuilding protein bonds: Damaged hair often has broken or weakened protein bonds (like disulfide bonds). Restructurants help to rebuild and reinforce these bonds, making the hair stronger and less prone to breakage.
* Filling in gaps: The product can fill in gaps and imperfections in the hair's cuticle (the outer layer), making it smoother and more resistant to damage.
* Improving elasticity: By strengthening the hair's internal structure, restructurants can help restore elasticity, making the hair less brittle and prone to snapping.
Common ingredients in restructurants may include:
* Keratin: A key protein that makes up hair.
* Amino acids: The building blocks of proteins.
* Hydrolyzed proteins: Proteins that have been broken down into smaller pieces, allowing them to penetrate the hair more easily.
* Ceramides: Lipids that help to bind the cuticle scales together.
Restructurants are often used:
* After chemical treatments: Such as coloring, perming, or relaxing, which can weaken the hair.
* On very damaged hair: Due to heat styling, environmental factors, or other stressors.
* As part of a deep conditioning treatment: To provide intense repair and nourishment.
In summary, a restructurant is a powerful hair treatment that aims to rebuild and fortify damaged hair from the inside out, improving its strength, elasticity, and overall health.
