The best way to find out is gathering information from repeat users of the hair dye, and that’s exactly what this post intends to do.

Just For Men hair dye typically last for roughly 3 to 4 weeks, but it starts to fade around the second or third week after initial application.

How to Use Just For Men Hair Dye

Most users and reviewers who have tried Just For Men hair dye corroborated the company’s claims that it’s not damaging to the hair.

While its impact depends on your usage pattern, unless you’re doing it the wrong way, you shouldn’t experience any negative impact.

With that said, here are some important things to look out for when applying Just For Men hair dye:

  • You can be allergic to the dye. So, it is highly recommended that you perform an allergy test 48 hours before applying it on your hair, and this recommendation isn’t only for Just For Men. Regardless of what dye you’re applying patch or allergy test is a crucial prerequisite.
  • If you allow the product to stay for longer than necessary on hair, you might end up with an excessively dark hue instead of the natural look you wanted to achieve.
  • Women should not try to use Just For Men on previously bleached or highlighted hair, as it will react unexpectedly with their fragile hair.

Tips to Make Your Hair Dye Last Longer

There are no hard and fast rules for making your Just For Hair hair dye last longer, apart from the regular application techniques from the manufacturer.

However, there are a few things you should try or avoid (as the case may be) for a long-lasting application:

  • Just like with other hair dye products, consider only using shampoo designed specifically for color-treated hair after applying Just For Men. Using something else will make the colors fade more quickly.
  • Some men prefer dying their hair before getting a haircut. However, doing it the other way around should give a more uniform yet adorable look; but this is just me thinking aloud, I’ve not put it to the test.
  • Swimming lovers hear me now; I hope you’re aware of the negative impacts of the chlorinated water from your swimming pools on your color-treated hair. Try avoiding swimming as much as you can after using Just For Men, and if you must, ensure you’re wearing a swim cap before entering the pool. You can also consider washing your hair with shampoo after leaving.
  • Do not wash your hair with warm water. The heat breaks down the chemicals in the dye, progressively fading your hair.
  • Avoid clarifying shampoo at all costs.

Step-by-Step Guide to Apply Just For Men Hair Dye

Nearly all you need to apply Just For Men hair dye are made available in the pack; you only need to get a bowl, a small toothbrush, and some old clothes to cover your hair after applying the dye.

If you have those ready, here’s how to apply Just For Men hair dye:

  1. Protect your body with an old T-shirt (from the old clothes) and cover your workspace with an old towel or paper to avoid dye stains.
  2. Put on your fancy hand gloves.
  3. Apply vaseline or petroleum jelly around your hairline, ear, and neck to protect them from dye stains.
  4. Pour some dye coloring into the developer and shake very well to mix evenly.
  5. Pour the mixture into the bowl you prepared earlier and stir to mix properly. Leave it to sit for around 3-5 minutes.
  6. Now, distribute the paste evenly all over grey hair areas using the small toothbrush and then brush it up to apply the dye evenly.
  7. Leave it to sit for 2 minutes before applying the dye to other parts that are less grey.
  8. If you want a dark color, let the dye mixture sit on your hair for at least seven minutes so it can cover all your hair correctly. However, five minutes should be sufficient for the natural look most people are after.
  9. When you achieve your desired hue, rinse your hair thoroughly until the water runs clear.
  10. Shampoo and condition.

This technique is what I use on all of my clients and it works perfectly every time. Interestingly, it works on dyes of any brand, not just Just For Men, unless the manufacturer requires an extra step during the application.

Also, determining how long to allow the dye sit on your hair can be tricky sometimes. Since you usually can see your hair during the application (I’m going out on a limb and assuming you have a mirror here), you can simply start rinsing once your hair achieves the desired shade.

If reading huge walls of text isn’t your thing, here’s a video tutorial on how to apply Just For Men hair dye with the provided kit.

Can a Woman use Just for Men Hair Dye?

Just because the name is ‘Just For Men’ doesn’t mean it’s poisonous for women. I’ve seen testimonies from ladies who tried the dye with no negative consequences, but it’s important to ask: why?

There are tons of better hair dyes designed specifically for women; why would you want to punish yourself by using something that isn’t just tiny, but is also not designed for you?

If you must use Just For Men as a lady, you want to buy multiple packs, as most hair dyes for men are tiny for a lady’s voluminous hair.

Is Just For Men Permanent Hair Dye?

While some of the dye’s marketing describes it as ‘permanent’, you shouldn’t expect any permanence, as it essentially fades after a few weeks.

Unlike most temporary dyes, however, it doesn’t fade to your natural gray; rather, it fades gradually to progressively lighter shades of the dye’s color, begging for another application to deepen the color.

If you’ll start using Just For Men, you should know you’re making a commitment. It’s not a big one; you’ll just have to re-apply the dye once every few weeks to maintain your hair’s artificial shade.
