SchwarzkopfColor Boost Color Vibrancy Booster, Dark Cool

I have tried a LOT of hair products since going grey 4 years ago as I got tired of hair color and seeing grey roots. I pour this into the palm of my hand without gloves and apply underneath my hair working to the top lastly. I wait 10 to 20 minutes and then add hair conditioner and a little water. I massage into my hair and leave on 5 minutes. Then wash out. It gives depth of some darkness to my grey hair. It tones the yellow tinge that grey hair has with use of well water. A gloved hand will stick to the hair so do not use gloves. When finished your palms will be deep purple. Use soap and water and wash your hands until the color is gone. The color will last in your hair for 4 to 6 weeks if you don't use shampoo daily.

Recently I started using a Beauty School to process and color my hair blonde. However, I never leave there with the golden blonde shade of blonde that I want, it’s always shades lighter. . Looking through Amazon, I came upon the Schwarzkopf Toner. I decided to purchase their golden blonde and try it out. Well, to my amazement, it turned out to be a fantastic product. It doesn’t matter what shade of light blonde I leave The Beauty School with. I wait a week, then use the golden blonde toner, and Voilà I have golden blonde. Beautiful golden blonde. I like that you can lighten the golden blonde depending on how many drops you use or Darken the shade. It’s so so easy to use. No mess no fuss. Use a small amount of conditioner, the amount of drops you want, mix it on the gloves provided n spread it around your hair like you do with conditioner. Wait 5 minutes, rinse n you have great shining color. Love ❤️ love this product. Highly recommend.

I followed instructions with 3 pumps to my conditioner. There should have been at least a browner tint to my blonde hair - nothing. So I added like 10 pumps to the conditioner - and it worked. The small bottle will not last long but it is a good temporary way to visualized whether I would like to dye my hair permanently darker.

The product itself is fine, but order from someone else. This seller sent me hair color manufactured in March 2021 (check the batch number), past its recommended shelf life, and I was advised not to use it. A request for a replacement earned me an even older box. Tried contacting the Schwarzkopf Store through Amazon, as instructed--but they did not reply to either of my inquiries.

Love the ease of use , and how it makes your hair color last between coloring.

This product is terrible...it did absolutely nothing to my hair color,the only thing it did was stain my scalp purple...it also stained my shower wall and tub 🙄 1000% DO NOT recommend buying this for any reason...it's just awful! Nothing positive to say about it!

It helps keep my hair a natural shade of blond while the past bleaching grows out, without using a permanent color.

Did not lighten my wife’s hair
