[SEASON3] GDS Color Boost Hair Dye Shampoo (+10M units sold Worldwide) ⭐

I mixed it up and honestly, this was very, very easy to apply. You just put it on like shampoo and wait anywhere from about three to ten minutes.
One small thing to keep in mind — if you leave it sitting too long before rinsing, it can leave some residue marks on your hands or around the sink. As long as you rinse on time, there’s no mess at all.
That’s what I liked most. No gloves, no stains on my skin, and nothing left behind in the bathroom when you follow the steps.
After rinsing, the color looked even and natural, especially around my hairline where the grays usually show first. Simple process, quick results, and very low effort. Using it once or twice a month feels perfect to keep the color fresh.

Using this was honestly easier than I expected. I just pumped a few times, rubbed it between my hands, and applied it exactly like a regular shampoo. No special technique needed.
I left it on for about 7 minutes, but I could already see the color starting to change around the 3-minute mark, especially where my hair was thinner and lighter. After rinsing and drying, the coverage looked even and natural — not dark or flat.
What sold me is how quick and predictable it was. No guessing, no mess, and no harsh feel afterward. This is one of those products where you finish and immediately know, “Yeah, I’ll keep using this.”

Before using this, the gray around my hairline was the first thing I noticed in the mirror. Especially near the temples and parting — it stood out even when the rest of my hair looked fine.
After using it, those areas look much more even. The gray isn’t jumping out anymore, and the color blends in naturally with the rest of my hair. It doesn’t look flat or dyed, just darker where it needs to be.
What I appreciate most is that it didn’t turn into a whole process. No gloves, no sectioning, no waiting around. Just a normal wash, and the difference shows once it’s dry.

I was starting to notice more and more gray at the roots — not all over, but those little white patches that show up first and make your hair look tired. That’s what bothered me the most.
After using this, those areas blended in way better than I expected. It doesn’t look dyed or heavy, just darker where it needs to be. The roots especially look cleaner and more even now.
What I like is that I didn’t have to do anything extra. No sectioning, no timing stress. Just shampoo, rinse, done. It’s subtle, but when you see the before and after, the difference is obvious.

I’ll keep this simple because the result kind of speaks for itself.
I had a lot of white hair and beard going in, so I wasn’t expecting miracles. But after using it, the color blended in way better than I thought. No harsh dye look, no weird shine — it just looks cleaner and more even.
What surprised me most was how normal it felt to use. It’s literally just shampoo. No mixing, no mess, no strong smell. Ten minutes later, I looked in the mirror and honestly thought, “Alright… that’s a win.”
If you want something quick that makes you look more put-together without trying too hard, this does the job.

I hate giving Reviews but this one I have to because I am amazed by your product and I need to share to a lot of people who is like me with gray hair! I totally love your product.I didn’t expect that with one shampoo application, my grey hair is fully covered for more than 2weeks now.So easy to apply and just for few minutes and the result is beautiful and my hair feels nourished and shiny.I don’t feel any burning in my scalp and strong odour.
Instead of going to the salon every1 & 1/2 month, now I can go less or even just use GDS and it is more healthier for me without any chemicals and I save money too.

absolutely love it!!! The first time I used, I didn’t know how to do it and still covered most of my whites. The second time I nailed. Covered all my whites and my hair is very shine, didn’t damage my natural color at all.

Does an excellent job my hair looks great as Does my wife.

color is great and easy to use with no skin staining , however it does nothing for beard color...... but do like it

Does not do what it promised
