Can you bleach over semi permanent hair dye? That’s the question one of our readers asked us. Before we answer this question, let’s talk a bit about the semi permanent hair dye and why you would want to bleach it out.
Is Semi Permanent Hair Dye Washable?
Semi permanent hair dye is a type of hair color that lasts longer than regular dye, but not as long as permanent dye. It also fades faster than permanent dye, so it needs to be touched up more often. Semi permanent dyes do not lighten the natural color of your hair, so if you have light brown hair and use pink semi permanent dye, the pink will only show up on top of your natural color — not on your scalp or root area.
Semi permanent dyes are washable with shampoo and water; however, they fade quickly when exposed to water and shampoo over time. The color will last about two weeks if you leave it untouched by water or shampoo; however, after one week you may start to see some fading around your face or neck area where there has been frequent contact with water (like during washing).
Will Semi Permanent Hair Dye Damage Your Hair?
Semi permanent hair dye is a great way to add color to your hair without having to commit to a full head of color. It’s also a safe alternative for people who are afraid of damaging their hair with permanent dyes.
The answer is yes, you can bleach over semi permanent hair dye. However, it’s important that you do it correctly — otherwise, you could end up damaging your hair and making the color application worse.
When Bleaching Your Hair Doesn’t Work
Bleaching your hair can be risky if you don’t know what you’re doing or if you use the wrong products. If you’ve bleached your hair before and it turned out orange or yellow instead of lighter, then you know how frustrating this process can be! Here are some common mistakes people make when trying to bleach their hair:
Using too strong of a bleach formula. All bleaches come with instructions, so make sure that you read them carefully before using them on your hair! If the instructions say that it’s not recommended for use on dark brown-black hair like yours, then don’t risk using it anyway — this will definitely damage your hair more than lightening it would have done!
What Does All This Mean?
The biggest issue is that semi-permanent hair color contains ammonia and other harsh chemicals. These ingredients help lift the natural pigment from your hair and deposit a new color. The chemicals in semi-permanent hair dyes will actually break down when exposed to heat or sunlight, which means that as soon as you shampoo your hair, all those chemicals are washed away.
So what does this mean for bleaching over a semi-perm color? Well, it means that if you want to go lighter than your natural shade, you’ll need to use more bleach than usual because there’s less of your natural color left in your strands. And if you don’t want to damage your hair, then it’s probably best not to try this at home!
How Long Does Semi Permanent Hair Dye Last In Your Hair?
Semi permanent hair dye is a great way to cover gray, brighten up your hair color, and add highlights. But how long does semi permanent hair dye last? And how do you know when it’s time to reapply?
Semi permanent hair dye is unlike most other types of dyes because it doesn’t actually remove any of your natural pigment. Instead, it coats the strand with color and then slowly fades out over time. This means that the shade will gradually get lighter until it disappears altogether. If you want to keep your color looking fresh, you’ll need to reapply semi permanent hair dye on a regular basis.
The amount of time it takes for your semi permanent dye to fade depends on several factors including:
- Your natural coloring and skin tone
- The brand or type of product used (some colors take longer than others)
- How often you shampoo (shampooing too often can prematurely fade your color)
Can You Bleach Over Semi Permanent Hair Dye? Do They Mix Well?
You can bleach over semi permanent hair color. However, it’s not recommended.
The reason is, bleach lightens the hair by breaking down the chemical bonds in the dye molecules. But if you use a semi permanent dye on bleached hair, it will not lighten enough to match your natural hair color.
It will just fade away in a few weeks or months (depending on how often you wash). So it doesn’t matter if you have dark hair or light hair, bleach over semi permanent dye is a bad idea!
But there are some ways around this problem:
- Bleaching your hair first and then coloring with semi permanents. This way you’ll get lighter results than if you just colored over bleached hair and it will be more natural looking as well!
- Using darker shades of semi permanents than what you would normally use on bleached hair. If your natural shade is dark brown but you want to go redder or pinker, consider using an orange or copper shade instead of burgundy or rose gold. You might not be able to get the exact same color but at least it will look better than if you used a shade that’s too close to your natural shade but still didn’t match well!
