Does Vinegar Set Hair Dye? [FAQs]

Have you ever heard that you can use vinegar to set hair dye? I’ve been curious about this beauty hack for ages. So, I decided to try it out and put it to the test.

Does Vinegar Set Hair Dye? An Experiment!

I’m sharing my results in this blog post, so you don’t have to experiment yourself – let me be your guinea pig!

The Experiment

I wanted to find out whether vinegar could set hair dye in a way that would make it longer-lasting. To do this, I used two boxes of different colors of box dye and divided my head into four sections. In one area, I followed the instructions on the box to apply the paint.

I applied the same color in the second section but added three tablespoons of white vinegar to the mixture before applying it. The third area got a different color using just the box instructions and no vinegar. The fourth area was again a different color with three tablespoons of vinegar added too.


The first thing I noticed was that all four sections felt slightly damp after rinsing them off – even when I hadn’t added any vinegar. However, when comparing each area side by side, vibrancy was different between those with and without vinegar added.

The sections with vinegar looked brighter and more vibrant than those without it, indicating that adding some simple kitchen ingredients can make a big difference in how deep your hair looks!

The next part of my experiment was to see if there was a difference in how long-lasting each section was over time. After shampooing my hair twice over two weeks, there wasn’t much difference between either group – with or without vinegar added faded equally over time.

So, unfortunately, it seems like adding vinegar won’t extend the lifespan of your hair dye – but at least you know your hair will look good while it lasts!

All in all, adding white vinegar to your hair dye can make a big difference in how vibrant your hair looks right after dyeing – but it won’t extend its lifespan significantly over time. Still, if you want an extra boost of color, then adding some simple kitchen ingredients can help you achieve that look!

Thanks for joining me on my experiment journey! Until next time… happy dyeing, folks!


If you want to set your hair dye, try using vinegar – ensure you don’t get it in your eyes! Vinegar acts as a natural fixative that helps seal the color in the hair shaft and gives you long-lasting results.

For those who want to try setting their dye with vinegar, be aware that it may produce a slight smell. A bonus is that leaving a vinegar rinse on your hair for about 10 minutes can help reduce any strong scents from the dye.

Finally, be mindful of how often you use a vinegar rinse – once or twice per month should suffice – as too much can cause dryness and breakage and dull the color of your hair.


What kind of vinegar is best for setting hair dye?

White vinegar is the most recommended type of vinegar to use when trying to set hair dye. It’s an acidic solution that helps stabilize your hair’s color and make it last longer. You can also use apple cider vinegar, which has a milder smell than white vinegar and is known for its cleansing properties.

Does vinegar help with fading hair dye?

Yes, using vinegar on your hair can help prevent your dyed hair’s fading. The acidity of the vinegar helps to close and seal the cuticles of your colored tresses, thus allowing the color to stay vibrant for extended periods. This technique works exceptionally well on more permanent dyes, like bleach or highlights.

Is it safe to use vinegar as a hair dye?

No, using vinegar as a direct substitute for chemical-based hair dyes is unsafe. While some people believe that diluted white or apple cider vinegar will give their locks a natural hue without damaging their strands, this method should be used with caution because there could be unforeseen side effects depending on your scalp health and the type of dye used.

Can I still set my hair dye if I don’t have any vinegar?

Yes! While using an acidic solution like white or apple cider vinegar certainly helps to stabilize and protect the color in your dyed hair, you can also try other alternatives if you don’t have any on hand.

For example, lemon juice or baking soda are suitable substitutes that contain acidity, which can help maintain vibrant hues in your tresses over time!

How often should I apply vinegar to my dyed hair?

Generally speaking, it’s best not to overwhelm your strands with too much acidity because this could end up stripping away some of the colors from your locks over time!

Therefore, applying a small amount of diluted white or apple cider vinegar once every two weeks is usually enough to keep your new tresses looking fresh and vibrant without damaging them further!
