Nanoplastia Step by Step: Sectioning, Processing and Thermal Activation

This is the professional execution sequence used in the Nanoplastia Professional System. It assumes a compliant professional line — in our protocol, Nanoplex Arginina™ — and a client who has already passed diagnosis.

1. Diagnosis and strand test

• Assess porosity, elasticity, density and chemical history before touching a product.
• Run a strand test on any hair with bleach, high-lift colour or repeated chemical services.
• Decide the target: full realignment, partial volume control, or postpone and reconstruct.
• Record the decision. A written diagnosis is what protects you if the client's expectation drifts.

2. Preparation wash

Clarify to remove residue, oils and product build-up so actives can penetrate. Number of washes is a diagnostic decision: resistant, high-density hair usually needs more, compromised hair needs fewer. Towel-dry and then blow-dry to the moisture level your protocol specifies — application on the wrong moisture level changes everything downstream.

3. Sectioning

Work in four quadrants, then subdivide into horizontal partings no thicker than the product can penetrate evenly. Thick sections are the number-one hidden cause of uneven results: the outer face of the strand gets full product and full heat, the inner face gets neither.

4. Application

1. 1Start at the densest, most resistant area — usually the nape or the crown depending on the head.
2. 2Keep the correct distance from the scalp as specified by the product.
3. 3Apply strand by strand, then comb through to distribute and align.
4. 4Keep total application time controlled so the first sections are not over-exposed while you finish the last.

5. Processing

Processing time is a range in the manufacturer's instructions and a judgement on the hair. Read the fiber: it should feel aligned and pliable, not slippery and not gummy. Elastic, stretchy behaviour during processing is a stop signal — rinse and treat, do not push on to the iron hoping it recovers.

6. Thermal activation

Follow your product's temperature specification — never a number you remember from another line. Keep the iron moving at a consistent speed, keep tension even, and count your passes deliberately rather than working until it "looks right", because the visual feedback lags the structural damage.

7. Cooling and finishing

Let the fiber cool completely before the finishing steps — the alignment stabilizes as it cools, and combing hot hair undoes part of the work. Finish according to the protocol of your line, then style dry to show the client the movement, not just the straightness.

8. Aftercare briefing

• Specify the wash window and the home-care products that maintain the result.
• Explain that sulfate-heavy shampoo and chlorine shorten longevity.
• Set the rebooking date before the client leaves the chair.
• Send a follow-up message a week later — it is the cheapest retention tool you have.
