Most people who want to hide their gray hair use permanent hair dye, which is readily available. After all, this dye is effective at covering up gray hair evenly and keeping it the longest. Unfortunately, there are powerful chemicals that can damage your hair.

On the bright side, these days you can find products that can hide gray hair without worrying about the damaging effects of permanent dyeing.

In particular, shampoos for darkening or whitening hair are the most popular alternatives to traditional permanent dyes.

Do Shampoo Bars That Darken Your Hair Really Work?

Generally yes. In fact, they serve as a simple yet effective solution for concealing gray hair without harmful effects. However, they do not last as long as permanent dyes.

How does a hair darkening shampoo bar work?

Like other hair darkening shampoos, this hair darkening shampoo bar coats the strands of hair with plant pigments, effectively covering the gray strands and making them appear darker.

Simply put, they sit on top of your hair without being completely absorbed into the strands of hair, so each time you wash your hair, the color fades and washes away. In contrast, permanent dyes work by removing some of the hair’s natural pigment and replacing it with the color of the dye.

Moreover, shampoo bars that darken the hair tend to work best when the shampoo is left on the hair for a while, allowing it to absorb more of the plant pigments present in the shampoo.

However, the downside of using a shampoo bar that darkens your hair is that it doesn’t last as long as a permanent dye. So if you want to keep your hair darker, you need to use it regularly.

Fortunately, shampoo bars that darken your hair can be gentler on your hair as they usually use more natural ingredients and avoid harsh ingredients like ammonia.

Because of this, even with more frequent use, you do not have to worry about long-term harmful effects on your hair and scalp.

Who uses shampoo bars to darken hair?

Darkening Shampoo Bar is highly recommended for those who want to maintain the color of their hair without dyeing them.

Also, this shampoo bar is a great solution for those who want to temporarily cover up a few white hairs as it will make their hair black rather than permanent.

Also, if your hair has a different chemistry, you might want to try a shampoo bar. This is because it is softer on the hair and can restore the tone of colored or faded hair over time.

Also, these shampoos contain red or copper pigments, so they tend to be widely used to maintain the red color. However, to counteract the orange tint that occurs in the strands, blondes should opt for a shampoo that contains a more purple or blue tint.

A Step-by-Step Guide to Using Hair Darkening Shampoo Bars

Wondering how to get optimal results from your hair darkening shampoo bar? Well, hair darkening shampoo bars can be used just like any other shampoo.

In this case, you just need to wash your hair thoroughly, shampoo, wait the time indicated on the packaging and rinse. However, to maximize the effectiveness of these hair darkening shampoo bars, it is best to follow these tips:

Step 1: Wet your hair first

To start, wet your hair with warm water until your hair is completely saturated. This will help create a bubbly lather and provide the best possible cleansing.

Step 2: Make Bubbles

Next, run the shampoo bar under water for a few seconds, then massage between your palms to create lather. Then massage the foam into your hair. Alternatively, you can massage the bar directly into your hair if you wish.

Step 3: Apply to hair

You then need to rub the lather into your hair just like you would with a regular liquid shampoo. But focus more on the scalp and roots.

Step 4: Rinse and condition your hair

When finished, rinse your hair thoroughly, leaving no shampoo residue behind. If necessary, you can do this using a regular conditioner or a solid conditioner bar after washing off the shampoo.

Step 5: Comb your hair

Next, after rinsing and conditioning your hair, use a towel to dry your hair and comb through the tangles with a wide-tooth comb. Start at the tip and work your way up to the root.

Step 6: Style

Finally, all that’s left to do now is blow dry or blow dry your hair and style it as usual! You now have beautiful dark hair.


For those who want to change their overall appearance, using a hair darkening shampoo bar can be the perfect choice. After all, you can change the color of your hair without as much damage as bleach and dyes.

Moreover, as to whether hair darkening shampoo bars work or not, the answer is yes. However, since they simply coat the hair to make it look darker, the effect doesn’t last as long as permanent dyes and fades away with each wash.

Nevertheless, the softer, less harmful properties of this shampoo bar make it a great alternative to permanent dyes. Especially since it can be used regularly without experiencing negative consequences.
