Vegan Flash Lightning Showdown: 30-Vol Bleach + Surprising Lift… Perfect for Trendy Hair We were intrigued by MANIC PANIC’s Flash Lightning kit, combining a 30-volume developer with vegan-friendly bleach powder. As detailed in our blog post, the dual-targeting action claims to lighten hair up to five levels—something we immediately wanted to test. The instructions were straightforward, and the product’s application felt forgiving, even for beginners. With its cruelty-free promise, it aligned well with our values. While one must handle bleach with care, our results were impressively even without professional guidance. The pastel green packaging added a playful touch, and the scent, though chemical, dissipated quickly. Overall, the kit delivered a solid lift and proved forgiving—making it a standout for at-home lighter results.
