Temporary Hair Color Wax 4.23 oz-Instant Hairstyle Cream Hair Pomades Hairstyle Wax for Party Cosplay Easy Cleaning (orange)

Do i use this before of after styling hair? I have curly/wavy hair and plan on straightening it when i use this product.

Is this safe to use on color treated hair? i have a lot of gray hair so i regularly color my hair. but i’d like to try this for a temporary change.
