Adjusting Shampoo Formula to Prevent Hair Flatness

Hello,

Thank you for your feedback on the shampoo formula. It's great that the formula makes your hair soft, smooth, and weighted, but it's understandable that you want to avoid the flatness and quick oiliness.

Regarding your questions:

Which ingredients cause hair flatness?
Based on the staff's response, the ingredients in your formula that can contribute to hair flatness are:

• Poly conditioner Pro (ID 1056)
• Guar Cationic (ID 186)
• Vitamin B5 (Panthenol) (ID 111)

These ingredients are conditioning agents. While they help with softness, smoothness, and detangling, using too much, especially in combination, can weigh down the hair, leading to a flat appearance and potentially faster oil buildup, particularly for certain hair types.

How to adjust the formula to prevent tangling and flatness?
The key is to find the right balance of conditioning agents. You've already tried reducing Poly conditioner Pro, which helped slightly but didn't eliminate the flatness. This suggests that the combined effect of the conditioning ingredients (Poly conditioner Pro, Guar Cationic, and Vitamin B5) is likely causing the issue.

To reduce flatness while minimizing tangling, consider these adjustments:

1. Reduce the total amount of conditioning agents: Instead of focusing only on Poly conditioner Pro, try reducing the percentages of Guar Cationic (currently 0.15%) and/or Vitamin B5 (currently 0.5%) down as well.
2. Experiment with ratios: You need enough conditioning to prevent tangling (which Poly conditioner Pro seems effective for) but not so much that it causes flatness.
   • Start by significantly reducing Guar Cationic and Vitamin B5.
   • Keep Poly conditioner Pro at a level that prevents tangling (perhaps slightly higher than the 0.6-0.7% you tried, if tangling returns, but lower than the original 1%).
   • Test different combinations. For example, try reducing Guar Cationic to 0.05-0.1% and Vitamin B5 to 0.1-0.3%, while keeping Poly conditioner Pro around 0.7-0.8%.
3. Consider your hair type: Fine hair is more prone to being weighed down by conditioners than thick hair. The optimal percentages will depend on your specific hair characteristics.

Finding the perfect balance will require some experimentation with the ratios of Poly conditioner Pro, Guar Cationic, and Vitamin B5. The goal is to use just enough conditioning to achieve detangling and softness without the cumulative effect causing flatness.

We hope this helps you find the ideal formula for your hair!
