Garnier Olia 6.65 Intense Red vs Bleach London Vivid Red Permanent Kit

Pick Garnier Olia if you want a predictable, well-documented red with full gray coverage and a gentle ammonia-free formula. Pick Bleach London Vivid Red if you want a bolder, more fashion-forward red and are willing to work with a smaller kit and less coverage guidance. Olia has far more owner feedback and a clearer track record; Bleach London scores higher on ratings but from a much smaller base.

• Choose the Garnier Olia 6.65 Intense Red if you need reliable gray coverage, a non-drip cream that is easy to apply yourself, and an ammonia-free formula you can repeat every few weeks.
• Choose the Bleach London Vivid Red if you want a vivid statement red and prefer a compact kit from a brand built around bold color.
