Why Some Nanoplasty Treatments Last Longer Than Others

Not all nanoplasty treatments are created equal — and the reason some last longer than others comes down to the active ingredients used. Most nanoplasty formulas fall into two main categories: glyoxylic-acid–based formulas and cysteine-based formulas. Both smooth the hair, both reduce frizz, and both can give beautiful results — but they work very differently, and that affects both longevity and the long term health of the hair.

Glyoxylic Acid: Longer-Lasting, but Not the Gentle Option

Glyoxylic acid is the ingredient responsible for the longest-lasting nanoplasty results. It works by creating a type of coating or “film” on the hair when heat is applied. This helps lock the hair into a smoother, straighter shape, giving the impression of stronger straightening and longer durability.

However, there’s a catch.

Although it’s marketed as gentle, glyoxylic-acid formulas can become damaging over time. The intense heat required to activate the acid can dehydrate the hair, make ends brittle, and in some cases cause long-term dullness or breakage. The more often this type of formula is repeated, the higher the risk of buildup and damage.

Cysteine-Based Nanoplasty: Gentler, Healthier, but Shorter-Lasting

Cysteine formulas, on the other hand, work with the hair’s natural structure. Cysteine is an amino acid already found in the hair, so these treatments focus on repairing, softening, and gently restructuring bonds. The result?

• Shinier hair

• Better long-term health

• Flexible movement

• Far less risk of dryness or breakage

The trade-off is longevity. Cysteine based nanoplasty may not last as long as glyoxylic acid, especially on coarse or resistant hair.

So Which Is Better?

Neither is “better” they’re simply different. Glyoxylic gives longevity; cysteine gives health. The best choice depends on your hair type, porosity, history, and what you value more: maximum duration or maximum hair integrity.
