1. 36-Type Protein Complex Blending Technology🔗
Hair Plus Protein Bond Ampoule Essence (18,486 Reviews, 4.7★)🔗
The #1 product, Protein Bond Ampoule Essence, features a complex blend of 36+ protein-related ingredients.
7-Peptide Complex:
- Hexapeptide-9 (EWG 1)
- Palmitoyl Pentapeptide-4 (EWG 1)
- Acetyl Hexapeptide-8 (EWG 1-2)
- Nonapeptide-1 (EWG 1)
- Copper Tripeptide-1 (EWG 1)
- Palmitoyl Tripeptide-1 (EWG 1)
- Tripeptide-1 (EWG 1)
Peptides are low-molecular-weight proteins formed by bonding 2+ amino acids. They strengthen hair's keratin structure and repair damaged areas.
20 Essential & Non-Essential Amino Acids:
- Essential amino acids (9 types): Lysine, Histidine, Threonine, Methionine, Valine, Isoleucine, Leucine, Phenylalanine, Tryptophan
- Non-essential amino acids (11 types): Arginine, Aspartic Acid, Serine, Glutamic Acid, Proline, Glycine, Alanine, Tyrosine, Cysteine, Asparagine, Glutamine
Amino acids are the basic building blocks of proteins. This formulation covers all 18 amino acids found in hair keratin to reconstruct damaged protein bonds.
6 Types of Hydrolyzed Proteins:
- Hydrolyzed Silk (EWG 1)
- Hydrolyzed Rice Protein (EWG 1-2)
- Hydrolyzed Soy Protein
- Hydrolyzed Elastin (EWG 1)
- Hydrolyzed Keratin (EWG 1)
- Hydrolyzed Collagen (EWG 1)
Hydrolyzed proteins are large protein molecules broken down into smaller sizes for easier penetration into hair shafts. Each derives from different sources (silk, rice, soy, elastin, keratin, collagen) to provide diverse amino acid compositions.
Additional Protein Ingredients:
- Silk Powder (EWG 1)
- Silkworm Cocoon Extract (EWG 1)
- Milk Protein Extract
- Keratin Amino Acids (EWG 1)
2. Leave-In Formula Technology🔗
No-Rinse Protein Ampoule🔗
Hair Plus Protein Bond Essence uses a "no-rinse hair pack" formulation. It's a leave-in type that can be applied to wet or dry hair after shampooing without rinsing.
Leave-In Formula Ingredient Design:
- Purified Water (EWG 1): Base ingredient
- Castor Seed Oil (EWG 2-3): Hair coating and shine
- Amodimethicone (EWG 1-2): Silicone emulsion for smooth texture
- Cetearyl Alcohol (EWG 1): Emulsion stabilizer
Leave-in formulas must be designed with a lighter texture than regular treatments. BeautyCore Lab combines silicone emulsion (amodimethicone) with botanical oil (castor seed oil) to deliver proteins to hair without heaviness.
3. Heat Protection Technology🔗
Hair Protection from Blow Dryers and Styling Irons🔗
Several products manufactured by BeautyCore Lab explicitly feature "Heat Protection" in their product names.
Heat Protection Product Line:
- Protein Bond Ampoule Modern Peach (592 reviews, 4.8★)
- Protein Bond Ampoule Pear & Freesia (550 reviews, 4.8★)
- Protein Bond Water Essence Pear & Freesia (1,446 reviews, 4.8★)
- Protein Bond Water Essence Modern Peach (1,208 reviews, 4.7★)
- Protein Bond Treatment Pear & Freesia (100 reviews, 4.9★)
Heat protection products are designed so that protein complexes prevent keratin denaturation from heat, while silicone and oil ingredients coat hair surfaces to buffer heat transfer.
Moisturizing + Coating Base:
- Glycerin (EWG 1-2): Moisture retention
- Butylene Glycol (EWG 1): Humectant
- 1,2-Hexanediol (EWG 1): Moisturizing + preservation
- Butylene Glycol Dicaprylate/Dicaprate (EWG 1): Emollient
These ingredients supply and maintain moisture in hair while enhancing protein ingredient stability.
BeautyCore Lab's Manufacturing Strategy🔗
3-Level Protein Complex Blending Technology🔗
BeautyCore Lab's protein bond products combine proteins at 3 different molecular weight levels.
| Level | Ingredient Type | Function | Count |
|---|---|---|---|
| Level 1 | Peptides | Low-molecular proteins penetrate hair interior and strengthen keratin bonds | 7 types |
| Level 2 | Amino Acids | Basic protein building blocks reconstruct hair protein structure | 20 types |
| Level 3 | Hydrolyzed Proteins + Protein Sources | Medium-molecular proteins form protective barrier on hair surface | 10 types |
These 3 levels of proteins have different molecular sizes, so they act on different parts of hair.
- Level 1 (Peptides): Penetrate hair interior, enter through cuticle gaps to repair damaged keratin bonds
- Level 2 (Amino Acids): Smallest size penetrates deep into hair core, providing raw materials for protein synthesis
- Level 3 (Hydrolyzed Proteins): Form protective barrier on hair surface and middle layers, preventing moisture evaporation
Key Findings🔗
Efficient Product Portfolio🔗
BeautyCore Lab's 14 Hair Plus brand products recorded 83,491 total reviews. That's an average of 5,964 reviews per product.
Core Product Line Focus:
- Protein Bond Ampoule Essence (no-rinse type): 5 SKUs, 36,889 total reviews
- Protein Bond Water Essence (water type): 3 SKUs, 24,027 total reviews

Safe Ingredient Design🔗
Among the top product's 56 ingredients, only 3 are EWG grade 5 or higher.
- Cetrimonium Chloride (EWG 6): Conditioning agent
- Fragrance (EWG 8): Product scent
Most protein ingredients are EWG grade 1, making the formulation safe for sensitive hair and scalp.
Frequently Asked Questions🔗
Q. Why use all 36 types of proteins?A. Hair keratin is composed of 18 types of amino acids. BeautyCore Lab formulates with 20 types of amino acids to cover all hair constituent amino acids. They add 7 types of peptides and 6 types of hydrolyzed proteins so that proteins of different molecular sizes act at different depths within hair. Small amino acids penetrate deep into hair core, medium-sized peptides fill cuticle gaps, and large proteins form surface protective barriers.
Q. What's the difference between leave-in formulas and regular treatments?A. Regular treatments are rinse-out types that require 5-10 minutes before rinsing after shampooing. Leave-in formulas are applied without rinsing, requiring light texture and fast absorption. BeautyCore Lab's Protein Bond Ampoule combines silicone emulsion with botanical oils to deliver proteins to hair without heaviness. It can be applied to wet hair after shampooing or to dry hair anytime, offering high convenience.
Q. How does heat protection work?A. Heat protection products are applied to hair before using heat styling tools like blow dryers or flat irons. Protein complexes prevent heat-induced keratin denaturation, while silicone and oil ingredients coat hair surfaces to buffer heat transfer. BeautyCore Lab's heat protection products contain amodimethicone (silicone emulsion) and castor seed oil to protect hair even at temperatures above 180°C (356°F). The protein complex formulation minimizes heat-induced keratin damage.
