Hair Care

We turn high-precision science into real, proven results for the Hair Care market. With exclusive methodologies, advanced technologies, and protocols that simulate real-world use, we rigorously assess the efficacy, safety, and performance of hair products, delivering clear, reliable, and highly visual evidence.

Our portfolio ranges from damage assessment, hydration, frizz control, and heat protection to advanced studies of hair growth, scalp health, environmental protection, shape retention, and performance across hair types such as curly, gray, and damaged hair. We combine high-precision instrumental techniques and innovative sensory assessments to generate data that strengthen claims, accelerate innovation, and increase brand value.

More than tests, we deliver applied scientific intelligence that turns innovation into competitive differentiation and commercial results.

Hair fiber integrity, strength & repair

Assess hair fiber integrity and mechanical performance to investigate damage, strengthen hair, prevent breakage, and support repair claims. From surface-level changes to internal structural alterations, these studies help characterize how hair responds to cosmetic treatments and repeated stress.

  • Cuticle integrity and surface damage
  • Internal hair structure and protein-related changes
  • Hair strength, flexibility and resistance to breakage
  • Breakage prevention under repeated brushing
  • Split-end repair and prevention
  • Improved detangling and softness
  • Hair fiber diameter and structural changes
  • Molecular and structural characterization of hair damage

Hair appearance, styling & texture control

Investigate how cosmetic products influence hair appearance, texture, and styling performance under different conditions. These studies support claims related to frizz control, curl definition, straightening, volume, shine, and hairstyle maintenance.

  • Frizz control under different humidity conditions
  • Curl definition, retention, elongation and elasticity
  • Curl definition and shape maintenance in textured hair
  • Straightening effect and long-lasting alignment
  • Volume control and fullness
  • Enhanced shine, mirror-like shine and shine on curly hair
  • Hair movement, bounce and natural-looking results
  • Faster hair drying
  • Reduced static and visible product residue or flaking

Hair color, pigment & color protection

Evaluate hair color changes and the performance of products designed to preserve, enhance, or modify hair color. These studies investigate color retention, fading, pigment distribution, and protection against factors that compromise color appearance.

  • Long-lasting color and reduced fading after washing
  • Protection against color degradation
  • Reduced pigment loss during cleansing
  • Color intensity and uniformity
  • Pigment distribution within the hair cortex
  • Color retention within the hair fiber
  • Anti-yellowing effects and maintenance of the desired shade
  • Gray hair color enhancement or recovery

Scalp health, hair growth & hair loss

Investigate scalp health and hair growth-related outcomes through clinical, instrumental, and biological approaches. These studies support the assessment of scalp conditions, hair density, hair loss, and changes in hair follicle activity, including investigations involving specific physiological or metabolic conditions.

  • Hair loss reduction and changes in the hair growth cycle
  • Hair density and hair diameter changes
  • Hair growth and follicular activity
  • Changes in hair follicle biological markers
  • Scalp barrier function and barrier efficiency mapping
  • Scalp redness, oiliness and dandruff-related signs
  • Changes in scalp condition and visible symptoms
  • Perceived improvement in hair and scalp well-being

Hair hydration, deposition & protection

Investigate how cosmetic ingredients interact with the hair fiber, including moisture-related properties, ingredient deposition, and protection against environmental and styling-related stressors. These studies help explain where ingredients are deposited and how products may help preserve hair integrity.

  • Hair hydration potential and water-related structural changes
  • Surface and internal deposition of cosmetic ingredients
  • Ingredient substantivity and distribution within the hair fiber
  • Silicone deposition and persistence on hair
  • Removal of product residues from the hair fiber
  • Protection against chlorine-related damage
  • Reduced deposition of environmental particles on hair
  • Thermal protection of hair protein structure
  • Protection against UV light-induced damage

Sensory performance & consumer perception

Understand how consumers and trained evaluators perceive hair and scalp performance following product use. These studies connect measurable changes with sensory attributes, professional assessments, and the perceived benefits that matter during everyday use.

  • Improved softness, smoothness and manageability
  • Easier detangling and combing
  • Improved wet and dry hair feel
  • Perceived frizz control and curl definition
  • Perceived improvement in hair appearance and styling results
  • Professional assessment of hair treatment performance
  • Perceived improvement in dandruff-related symptoms
  • Perceived improvement in hair loss-related concerns
  • Improved well-being associated with hair and scalp condition
