Function: Damage care, increase hydrophobicity of bleach-damaged hair, reduce hair frizz, improve combability, and enhance hair texture
Description of certain amino acids:
Basic Amino Acids
Basic amino acids enhance hair strength and shine.
Neutral Amino Acids
Neutral amino acids counter strands from drying out and improve combability, smoothness, and silkiness of hair.
Acidic Amino Acids
Acidic amino acids increases the moisture of hair, improving combability, and smoothness.
Alanine
A non-essential amino acid administered to moderate the ionic equilibrium; neutralising the static electric conductivity and reducing hair frizz. It is also able to increase the hair surface hydrophobicity of bleach-damaged hair.
Histidine & Phenylalanine
Essential amino acids used to improve the tensile strength of hair shafts in water.
Pyrrolidonecarboxylic Acid (PCA)
PCA improves colour retention for dyed hair, while sodium PCA is used as a moisturiser.
Arginine
An essential amino acid applied to reduce the oxidative change in contact angle and tensile strength. It is furthermore used to prevent the undesirable attack by hydrogen peroxide on hair proteins and hair surface lipids.
Active in: Strength Shampoo, Recovery Conditioner, & Growth Serum
