Dexe Black Hair Shampoo Review: Before And After

Share With Friends and Family

“Dexe Black Hair Shampoo colors your hair black in just 5 minutes and lasts up to 4 weeks,” says the product’s marketing material, but how true is this claim? It’s been a long time since I wanted to write about this hair care product, and now, enough of the procrastination, let’s get this out of the way.

Ever since I started my career as a professional hairstylist, I’ve always experimented with different brands of hair dyes to see the results, and now, I can share some of them with you.

So, last month, I bought the Dexe Black Hair Shampoo dye pack with ten sachets, and today, I used it on a client with almost brown hair. Since he was hurrying to make it in time for a ceremony, I had to wash off the dye before the recommended time.

I expected the worst, but guess what! It was still okay, even though I washed away some of the shampoo dye.

Right here in this review, I will show you the best and quickest way to apply this shampoo dye, the ingredients, and, most importantly, my thoughts about the product, with a before and after picture.

But before I continue, I would like to tell you that this isn’t a sponsored post. It’s an unbiased personal review of my experience using the hair shampoo that I’d love to share with you.

Dexe Black Hair Shampoo Review

The shampoo dye had been sitting on my shelves for months before I finally mustered the courage to use it on a client, no thanks to a pessimistic colleague who kept convincing me it wouldn’t work. Since nobody else has tried the shampoo, I couldn’t bring myself to experiment with an unwilling customer. 

According to the manufacturer, the shampoo dye wasn’t made just to change hair color. Here are some other beneficial properties of Dexe Black Hair Shampoo:

  • It strengthens and nourishes the hair and roots.
  • It gives the hair a silky and shiny look.

I must confess that after the whole process, I was impressed with the resulting black color. I will keep updating the review as I continue to use it.


Not very surprisingly, our test subject for Dexe Black Hair Shampoo came back two weeks later, and the color washed off. I asked him how many times he washes his hair; he replied: “Every day.”

I also used it on a lady and it lasted for a similar length of time, which in my opinion, isn’t too bad for a black hair shampoo. Nobody expects dye to work forever, and when you’re buying a multipurpose dye with three functions, you certainly don’t expect it to last eight weeks.

So, your fear is likely true: Dexe Black Hair Shampoo works but doesn’t last as long as regular hair dye. The longest you can hope for is three to four weeks, and that’s when you don’t have a daily hair-wash routine.

Dexe Black Hair Shampoo Ingredients

There are two agents in each Dexe hair shampoo sachet- Developer and Colourant.

Part A Ingredients: Aqua, Sodium Laureth Sulfate, cocamide DEA, Glycolstearate, sodium lauryl sulfate, propylene Glycolstearate, p-Phenylenediamine (PPD), m-Aminophenol, resorcinol, sodium erythorbate, Acrylates/Steareth-20 methacrylate copolymer, Cocamidopropyl betaine, Parfum, ethanolamine.

Part B Ingredients: Aqua, Sodium Laureth Sulfate, cocamide DEA, sodium lauryl sulfate, propylene glycol, Cocamidopropyl betaine, Parfuy, disodium phosphate, phosphoric acid, hydrogen peroxide, oxyquinoline sulfate, and etidronic acid.

Dexe Black Hair Shampoo Application Instructions

If you are using it for the first time, the first important thing you should do is a strand or patch test. This test will show you if your hair is compatible with the dye, so you don’t experience full-scale allergic reactions. 

To do this, you should take a small amount of the shampoo dye content and apply it to the skin behind your ears. Or apply to some hair strands that are not easily visible.

Allow the dye content to sit on your hair or skin for 24 hours. If you notice any redness, itching, swelling, or any other symptom of allergic reactions, discard the shampoo immediately.

If the patch test went positively, however, here’s a step-by-step application instruction for Dexe Black Hair Shampoo.

Step 1: Wash your hair normally and allow it to dry. Hair dye works best on dry hair, so the few hours wait for your hair to dry is always worthwhile. 

Step 2: Apply any oil around your hairline, neck, and ear to avoid staining. I recommend you wear black overall or apron with a black towel around your neck if you have long hair.

Step 3: Wear your protective gloves; there are ten pieces of free nylon gloves in the full pack, and each piece of the glove has a pair (for left and right hands)

Step 3: Squeeze out the dye content into a small bowl (either stainless or plastic). Mix thoroughly and apply on your hair. Don’t worry if the shampoo dye starts turning black quickly. (That’s it’s nature)

Step 4: For ladies, remember to divide your hair into four sections and clip each. Make sure the dye is evenly spread, section after section till your hair is completely covered. If your hair is thick and(or) long, use 2-3 sachets at a time.

Step 5: Finally, rinse hair thoroughly with water and shampoo. You can blow-dry or leave it to dry out by itself.

Note From Manufacturer: The coloring effect can be affected if the temperature is low or the hair is hard or resistant. If the black color you achieved is not perfect, increase the time you allow it to sit on your hair to an extra 15 – 20 mins. 

Price And Where To Buy

Dexe Black Hair Shampoo is relatively popular, so you should be able to find it in your neighborhood supermarket. If you still can’t find it, however, you can get it on Amazon (#ad) or any other online store.

I purchased the pack I used on my clients from a local supermarket for $20. The price may be higher or lower, depending on where and how you’re buying (offline or online).

Before And After Picture

I didn’t have access to a studio camera for the before and after pictures, but I hope my amateur try gets the point across.

Is Dexe Black Hair Shampoo Safe?

In my experience, none of my clients showed any adverse reactions to the shampoo, nor did it exhibit any properties that would make me deem it unsafe. Also, none of the items in its ingredients list appears to be unsafe, so you should have no problems using it.

However, this is not an endorsement of Dexe Black Hair Shampoo, and we’ll always advocate for strand and patch testing before applying any hair dye. No hair product is 100% safe for 100% of people; you don’t want to learn about your allergic reaction by actually suffering it.

Final Thoughts

Dexe Black Hair Shampoo won’t last for as long as a regular black hair dye, but it’s an excellent option for people after a temporary black color. It’s also not as expensive as regular dye, so that makes it an even more powerful choice.8
