Suitability of Zinc Pyrithione and Hydrolyzed Vegetable Protein in Water-Based Pomade

Based on the information provided:

Regarding adding ingredients to your water-based pomade formula:

1. Zinc Pyrithione (for anti-dandruff): This ingredient is not suitable for use in a pomade. Anti-dandruff ingredients like Zinc Pyrithione need to be applied directly to the scalp to be effective. Since pomade is typically applied to the hair itself and does not make significant contact with the scalp, you would not see the desired anti-dandruff effect.
2. Hydrolyzed Vegetable Protein (for hair nourishment): This ingredient can be used in your pomade formula. Hair nourishing ingredients work on the hair strands, which is where the pomade is applied.

Therefore, between the two ingredients you mentioned, Hydrolyzed Vegetable Protein is suitable for adding to your pomade, while Zinc Pyrithione is not. Other hair nourishing ingredients could also be considered if you are looking for alternatives for hair conditioning benefits.
