Proteins Structural Proteins Research: Moderate

Scientific Name

Hydrolyzed Keratin

Classifications

Processing: enzymatic-hydrolysis
Source: animal
Type: hydrolyzed-protein

Benefits

  • Supports hair strength and resilience
  • May improve nail hardness and growth
  • Provides building blocks for hair and nail structure
  • Helps repair damaged hair
  • Supports skin barrier function
  • May reduce hair breakage and brittleness

Specific Properties

  • Enhanced bioavailability and absorption
  • Smaller peptide size for better utilization
  • More soluble than intact keratin
  • Contains essential amino acids and cysteine
  • Derived typically from wool, feathers, or horns

Safety Notes

Generally recognized as safe when used as directed. Derived from animal sources (typically sheep wool, feathers, or horns), so not suitable for vegans. Those with allergies to wool or feathers should use caution. Limited data on long-term supplementation. Topical products are generally well-tolerated.
