Why Reparex against grey hair?

Directly from the Slovak manufacturer

Healthy alternative to hair dyes

Stop greying hair and restore your natural hair color from the inside. Reparex against grey hair is a unique enzymatic liquid that restores the hair to its original color. Unlike the classic hair dye, Reparex does not cover hair, but acts from the inside thanks to special enzymes. The greying is removed gradually by blocking the production of hydrogen peroxide in hair follicles and the whole process looks natural.

Re-pigmentation Process

How To Reverse Grey Hair?

The unique enzymatic composition of Reparex works directly inside the hair.
What causes grey hair?
Grey hair is caused by the accumulation of hydrogen peroxide inside the hair follicles. The result is the oxidation of the natural hair pigment, melanin.
If melanin gets oxidized, only its colorless form enters the hair.
How can we stop or reverse greying hair process?
First, we must remove the accumulated oxygen from the oxidized colorless melanin. At the same time, we must prevent ongoing oxidation.

Two potent substances will help us with restoring grey hair:

→ glucuronate reductase (enzyme)
→ silver compounds

Thanks to their combined effect, Reparex successfully removes oxygen from oxidized colorless melanin. As a result, the melanin is successfully colored to its original color. With this simple procedure, Reparex restores the color of your hair from inside it.

Again, thanks to the use of medicinal herbs and our know-how, our product can alleviate hair loss and even, in some cases, can revive hair roots to restore growth. It’s easy to use and you’ll learn it very quickly. 

Before and After reviews

"At first, I liked the gray and thought I could work with it but as it took over I realized I was looking a lot older than I wanted to and decided to give Reparex a try. I am now into my second bottle and am loving it. It is fast, easy, effective and has no odor."


From our customers

I'm glad I discovered Diamond Yacca. I have been using it for more than a year now, 2 capsules daily. During that time, I found that I was feeling better overall and that my high blood pressure had returned to normal. I am very satisfied with this product and I will continue to use it. I recommend anyone who has similar problems with blood pressure and blood vessels as I do to try to use it. I believe it will help.

Proven product, top quality. It needs to be tried.

Capt K. Cosmetics

I have been using it continuously since 07/2021. I currently dose 2 tablets 4 times a day. So it suits me so far, so I plan to continue this scheme in the next period.

I have dyed my hair, can I still use Reparex?

Using Reparex on dyed hair will cause adverse effects. Reparex doesn't work properly on dyed hair as it can cause discoloration of your hair.

How long does it take to see the first results?

Our customers report the first results within the first week. However, it depends on the density, length of your hair, your age and the period of how long you've had grey hair for.

I've started Reparex treatment, can I keep using a shampoo?

Yes, you can. There are no adverse effects or contradictions. You can keep using your favorite shampoo.

Can I use a hair drier after Reparex application?

Yes, you can. Using a hair dryer can actually speed up the re-pigmentation process.
