I want to dye my hair myself.

My gray hair has increased significantly lately, so I've started dyeing it regularly at the hair salon.

My hair is thin and weak, so I want to try dyeing it myself to minimize damage, but I'm not sure which product is good.

I saw on a home shopping channel that dyeing your hair yourself doesn't look too difficult, so I want to give it a try. Could you please recommend some products you've used that are easy for a beginner like me to use?
