Herbal Nourishing Grey Hair Covering Shampoo Formulation

Here is a suggested formulation for a grey hair covering shampoo with nourishing herbal extracts:

This formulation uses a semi-permanent color system combined with ingredients to nourish the hair and potentially reduce the appearance of new grey hair over time.

Key Ingredients:

• Semi-Permanent Hair Color Shampoo Base: This forms the base of the shampoo and is designed to work with semi-permanent colorants.
• Semi-Permanent Hair Colorant (Natural Black): Provides the black color to cover grey hair. You can adjust the shade or use other colors as needed.
• GreyReverse™ (Palmitoyl Tetrapeptide-20): A peptide ingredient that helps stimulate hair pigmentation to reduce the occurrence of grey hair over time. It is recommended for long-term use.
• Hydrolyzed Keratin: A protein that helps to restore and nourish damaged hair, improving strength, moisture, and shine.
• ColorFix™: Helps semi-permanent hair color adhere better to the hair and last longer by coating the hair with cationic properties.
• Dried honeysuckle flowers (for water-based, no color bleed): A natural herbal extract suitable for water-based formulations, adding a natural conditioning or beneficial property. Other water-based herbal extracts can also be used.

Sample Formulation Structure:

• Semi-Permanent Hair Color Shampoo Base: ~90%
• Semi-Permanent Hair Colorant (Natural Black): ~10%
• GreyReverse™: 1-5% (recommended 5% for best results)
• Hydrolyzed Keratin: 0.1-5.0% (recommended 2% for rinse-off shampoo)
• ColorFix™: 0.1-5.0% (recommended 0.6% for shampoo)
• Dried honeysuckle flowers (or other water-based herbal extract): As desired (follow supplier recommendations)
• Other desired additives (fragrance, preservatives, etc.): As needed

Notes:

• This type of shampoo provides semi-permanent color that washes out gradually. Regular use is needed to maintain the color.
• Semi-permanent color may not provide complete coverage for all grey hair, especially if the hair is very resistant.
• Adjust the percentage of colorant based on the desired intensity.
• Ensure all ingredients are compatible and follow recommended mixing instructions and pH adjustments (e.g., for ColorFix™, maintain pH not lower than 8.0).

This formulation provides a starting point, combining grey coverage with nourishing and hair-strengthening ingredients, plus the option to include natural herbal extracts.
