L'Oreal Magic Retouch Disappointment

I bought a L'Oreal Paris Hair Retouch product (Black) about a month ago to cover my slight grey hairs. This product is so disappointing for the price I paid R110 at Foschini. It makes my hair look dry and damaged, honestly. Whenever I touch my hair, my fingers are black. Its a great idea, but absolutely not recommended.

This is so disappointing. I refuse to continue using it. I cannot wait to wash my hair for it to be washed off.

I might as well keep dyeing my hair black.. this is more effective and my shine remains.
