Love Moon Instant Shampoo or VCare Herbal Dye - Suggestion needed

Hi Friends,
Have you ever used or heard of Love Moon Instant Black Shampoo. It is a instant black dye for grey hair. The product contains two packets one is a shampoo and another one is a conditioner. The packet clearly mentions the ingredient list like ammonia, parabens, dimethicones, etc. I have less grey hair (10 to 20 max), but that is bothering me a lot. Mine is a super dry hair and henna is a big no no for me.


Please suggest me some good hair care tips that could cover my grey hairs and prevent from getting again.

Thanks in Advance,

Divya
