The science

Biotech-led scalp care, engineered for textured hair.

Our formulations are developed using advanced dermatological research, scalp barrier science & the latest in biotechnical cosmtic science.

Why Scalp Science Comes First

The scalp is biologically active skin.

It regulates inflammation, microbiome balance, follicle health, and hair growth cycles.

When scalp function is compromised — through buildup, barrier disruption, mineral accumulation, or irritation — hair outcomes suffer regardless of styling or moisture routines.

Healthy hair growth is downstream of a healthy scalp.

Barrier Integrity & Scalp Health

A compromised scalp barrier leads to:

  • Increased water loss
  • Heightened sensitivity
  • Chronic flaking and irritation

Our approach prioritises barrier restoration, over aggressive cleansing.

We focus on:

  • Skin-identical lipids
  • Film-forming humectants
  • Anti-inflammatory actives
  • pH-optimised systems
Microbiome Balance

The scalp hosts a complex microbial ecosystem.

Rather than broad-spectrum antibacterial formulas, TROI uses:

  • Targeted antifungal actives
  • Microbiome-supportive ingredients
  • Controlled delivery systems

This allows the scalp to self-regulate, reducing recurring irritation.

Chelation & Hard Water Impact

Hard water minerals and environmental metals bind to hair and scalp proteins, leading to:

  • Reduced product performance
  • Increased dryness and brittleness
  • Dullness and reduced elasticity
  • Persistent scalp irritation

Chelation gently removes these ions without disrupting the scalp barrier — restoring balance and improving efficacy.

Specifically Designed for Textured Hair

Textured hair is often treated as a single category.

In reality, it spans diverse fibre structures, scalp conditions, and care routines, each with different formulation needs.

TROI products are developed with consideration for a range of textured hair types, including coily, curly, and tightly textured patterns, to assess compatibility and performance across real-world use conditions.

Our approach includes:

  • Evaluation across multiple textured hair types during product development
  • Assessment alongside common textured-hair routines, including protective styling and product layering
  • Use of cosmetic actives supported by published scientific or in-vivo data relevant to scalp health or hair fibre care
  • Formulation at concentrations aligned with supplier data and publicly available research

Precision matters — particularly for hair types that have been historically under-represented in research.
