Ingredients to Add Weight and Smoothness to Herbal Shampoo

Based on your current herbal shampoo formulation using kaffir lime water, Coco Betaine, Coco Foam, Sugar Thick, and thyme preservative, it's understandable that you're experiencing a light feel without using a conditioner. To add weight and smoothness to your hair directly within the shampoo, you can incorporate conditioning agents.

Here are a few ingredients you can consider adding:

• Silicone Hi-Cond: This is a liquid silicone specifically designed for conditioning shampoos. It helps make hair soft and smooth, prevents tangling, and provides a coating effect that can add a feeling of weight. Recommended usage rate in shampoo is 0.5-1.5%.

• Clear-Cond™ (Quaternium-80): This is a highly effective water-soluble conditioning agent. It provides good smoothness and can be used in clear formulations. Recommended usage rate in shampoo is 0.2-2%.

• Hydrolyzed Keratin (Liquid): While not primarily for adding weight, Hydrolyzed Keratin is a protein that can penetrate and help restore damaged hair, improving its strength, moisture, and shine. This can contribute to the overall feel and appearance of healthier, smoother hair. Recommended usage rate in shampoo is 0.1-5.0% (suggested 2.0%).

How to incorporate:

These ingredients are typically added to the water phase of your shampoo formulation. Follow the specific mixing instructions and recommended usage rates for each ingredient to achieve the desired results.

Adding one or a combination of these conditioning agents should help your hair feel smoother and have more weight after washing, even without using a separate conditioner.
