Which self-dyeing product was the best?

Personally, I think 'L'Oréal Excellence Cream' is the best among DIY hair dyes.

I have been using only L'Oréal ever since I studied abroad.

Other brands only have before and after photos of light hair dyeing.

I started using L'Oréal because I liked that it included before and after photos of black hair dyeing.

Shampoo and conditioner are also included separately inside.

I liked that they seemed genuinely concerned about their customers' hair damage.
