FAQs

RUTAM Nº8 works on both washed and unwashed hair — anytime your hair needs repair.

It is designed as a leave-in treatment that continues to work for hours, especially while you sleep.

"The 8-Hour Miracle"

The name “Nº8” comes from our clinical concept of 8 hours of continuous repair.

Applying it before bed lets the 8-Complex system work overnight, restoring softness, strength, and smoothness by morning.

How to use for best results

  • After shampooing (recommended): towel-dry your hair, apply from roots to ends.
  • On dry hair: smooth a small amount through mid-lengths and ends whenever hair feels dry or damaged.
  • Before bed: apply evenly, leave overnight, and wake up with visibly healthier, smoother hair.
  • Do not rinse. Nº8 is designed for continuous absorption.

Nº8 strengthens thin, fragile, or chemically damaged hair fibers — so letting it stay on the hair (day or night) maximizes results.

No. Nº8 is not a styling product.

It does not use hairspray polymers, silicone buildup agents, or cosmetic hold ingredients.

The fuller, lifted effect comes from fiber biology, not styling:

✓ Nº8 thickens the appearance of hair

Its Tri-Peptide Matrix + Biofunctional Proteins reinforce the hair shaft, helping thin hair look stronger, denser, and more resilient.

✓ Repairs and smooths damaged strands

By sealing micro-cracks and strengthening weak spots, hair naturally looks smoother, shinier, and healthier — which visually increases volume.

✓ Improves the scalp–root environment (without being a scalp product)

It supports a healthier foundation at the root level, allowing strands to grow stronger and appear fuller over time.

You feel volume because your hair is stronger — not because it’s “styled.”

It’s clean, weightless, and natural.

Nº8 is a hair serum first, not a scalp tonic.

Apply it to:

  • Roots → for strengthening weak, thin, or flat roots
  • Mid-lengths → for damage repair and hydration
  • Ends → for smoothing frizz and preventing breakage

Then gently comb or use your fingers to distribute evenly.

If blow-drying, lift the roots with your fingers — Nº8’s biofunctional actives help hair hold natural bounce.

Result: fuller roots, smoother lengths, stronger ends.

Yes — Nº8 is designed for daily use.

It’s silicone-free, non-greasy, and absorbs quickly, so it will not weigh down the hair or create buildup.

If your hair is very fine, use 1–2 pumps.

If thick or damaged, use 2–4 pumps.
