About Colour B4

Colour B4 Extra Strength hair color remover is the safest and most beneficial way to get rid of undesirable hair color and get back to the original hair color.

Steps to Use Colour B4

Here is the step by process to apply Colour B4 on your hair so that you can have better results:

1. Before applying Colour B4 on your whole hair, you can do a patch and strand test.

2. Firstly, mix bottle A with bottle B and shake it well for 60 seconds. Remember to use the gloves provided with it.

3. Now, divide your hair into four sections. Start working from underneath and gently apply the product through your hair. If your hair is longer, then you may need two or more packs of the product.

4. Start applying it from roots to tip and once it is completely covered in your hair, cover your hair with cling film. By doing such, it will generate heat and encourage cuticles to open.

5. Keep it for 60 minutes on your hair. Then, start rinsing it by using warm or hand-hot water.

6. Once you are done with rinsing, start applying half of bottle C (buffer). Apply it through your hair as you apply a regular shampoo.

7. Now, rinse it for 5 minutes and then apply the remaining half of bottle C and again rinse it for 5 minutes.

8. And the process is done. You can see the results in natural daylight after drying your hair. You can repeat the process up to three times a day for very dark and old dyes in the hair.

Advantages of Colour B4

The main advantage of Colour B4 is that it removes the permanent, semi-permanent hair color and colorbuildup from your hair.

Another advantage is that the conditioning buffer of the product prevents reoxidation so that it instantly allows the re-color of your hair and it also conditions and strengthens your hair.

Disadvantages of Colour B4

One of the disadvantages of color B4 is that it is time-consuming as you have to leave it for an hour, then rinse it, then clarify it so it is a long process.

Another disadvantage is that you cannot use semi-permanent or permanent dye straight afterward as you have to wait for 7 days and 3 washes so that your old hair color cannot reoxidize.

Colour B4 Review and Hair Loss Concerns

One of the top searches online is Colour B4 review hair loss. Many people worry whether using this product will make their hair fall out.

Here’s the truth:

• Colour B4 doesn’t directly cause hair loss. It doesn’t contain bleach or high-volume peroxide that can damage follicles.
• But, some users notice increased shedding after use. Why? Usually it’s because the hair is already fragile from repeated colouring, heat styling, or poor hair health. The washing-out stage of Colour B4 requires heavy rinsing and shampooing, which can loosen weak strands.
• If your hair is already brittle, it may feel drier and break more easily after the treatment, giving the impression of hair loss.

💡 Tip: Always deep condition after using Colour B4. A protein or repairing mask helps restore strength and moisture.

Colour B4 Reviews on Red Hair

Red hair dye is famously stubborn. It clings tightly to hair and often leaves a stain even after removal attempts. So how does Colour B4 perform on red shades?

• Works better on lighter reds. If you’ve dyed your hair a copper or light auburn, Colour B4 usually does a decent job stripping away most of the colour.
• Darker reds are harder. Burgundy or intense cherry tones may not come out completely. Many users report their hair turns to a lighter, brassy orange rather than going back to the original shade.
• Multiple applications might be needed. Some people use Colour B4 twice in a row to get better results on red dye, but this can increase dryness.

Example from reviews: One customer who had dyed her hair red for years said Colour B4 removed a lot of the buildup, but she still needed to tone the leftover orange. Another person using it on bright red hair saw it fade to a warm brownish-orange after one application.

Colour B4 Review on Dark Hair

Now let’s look at Colour B4 review dark hair. Dark shades, especially black and very deep brown, are some of the hardest colours to strip.

• Removes some of the black tones. Users often find that black dye fades to a dark brown after Colour B4. Rarely does it take you all the way back to your natural colour in one go.
• Multiple applications are often necessary. Many reviewers say it took two or three attempts before their hair looked lighter.
• Staining is common. Black and dark brown dyes can stain the hair shaft permanently. This means Colour B4 may lighten the look but not completely remove every trace.
• Natural undertones come through. If your natural hair has warm tones, you might see orange or reddish shades after removing black dye.

Tip: If you’ve dyed your hair black for years, don’t expect a miracle. Colour B4 can fade the dye but not fully erase long-term buildup.
