Is there a type of shampoo that covers grey hair and turns it into black within 3 months if used dai

I recently bought a hair product manufactured in malaysia which claimed that if used daily, it can cover grey hair and turn your hair silky smooth.

Is there a type of shampoo that covers grey hair and turns it into black within 3 months if used daily?

I don't think a shampoo exists that will do that for you.

If you're looking for something inexpensive you can do yourself, try purchasing a bottle of color glaze. They come in all different price ranges and colors. Ask a stylist which brand or color she would recommend. The good thing about the glazes? You use them at home in your shower about once a week!

I have been a hairstylist for 22 years, I have never heard of a shampoo permantly turning your hair another color. It's just not possible. It can be a temporary thing. If you want to change your hair color, you can buy dark brown and black color with no ammonia, just put the color on, let it process and shampoo it out. That's a guarantee. Your hair will grow so once you see gray again, time to color again. Usually 1.5 months.
