My dad had a very pleasant experience using Quick touch 1 minute Hair color and highly recommends it to everyone who color their hair.
I must say I have not used any hair color that does its job so fast. I went to shower almost instantly after i applied the product. It must have been on my hair for not more than 2-3 minutes. I am seriously impressed! My grays are covered and my natural hair color remained the same. I did not notice any harshness in my hair too.
