Before anything else, know that there are three different kinds of hair dyes to determine how long they last.
These kinds of hair dyes actually contain ammonia, which bleaches the natural hair to dye the actual hair color of your liking. However, most people don’t like ammonia in their hair dye since it causes breakage, dryness, and damage to the hair.
One of the most important things to remember is that you absolutely need to bleach your natural hair if you choose permanent hair dye. This saves you the effort, time, and money as you don’t have to buy a bleaching set and bleach your hair multiple times in order to dye your hair dark purple.
Permanent hair dyes typically last for 6 to 9 weeks, approximately 32 washes.
Unlike the permanent hair dyes, semi-permanent penetrates the hair to a limited extent only. These kinds of hair dues don’t bleach the hair and contain a tiny portion of ammonia, making it friendlier and less damaging to your hair. And this is exactly the reason why semi-permanent hair dyes don’t last long.
Semi-permanent hair dyes usually last for about 4 to 6 weeks with approximately 28 washes.
Lastly, semi-permanent or temporary hair dyes don’t have ammonia and don’t need bleaching. Instead, it has an alkaline agent, which is the developer solution. This developer solution aids in dying the hair shafts.
Demi-permanent hair dyes typically last for about 2 to 3 days, with 2 to 3 washes the most.
Follow these fool-proof steps to achieve that dark purple hair dye you desire.
It is crucial to recognize your current hair color in order to somehow know the sort of outcome you will get. Just to remind you, every hair dye has a color chart printed on the box. It is in your interest to always check the color chart to get a grasp of the possible result.
Lighter hair color, for example, will react very differently to darker hair. The fact that you are applying a dark purple hair dye without bleaching doesn’t mean the outcome would be unpredictable.
After determining your current hair color, prepare for dying. You will need to wash your hair with a clarifying shampoo before applying the dark purple hair dye. Take note that these kinds of shampoo are pretty damaging to the hair, especially if you naturally have dry hair.
So prepare your fave hair conditioner to restore the needed moisture of your hair to avoid brittle and dry hair.
Carefully rinse your hair and have it air dried. Once the hair is dry, part your hair into four sections and clip them to keep it in place. It is best to make more sections if you have thicker hair for a more effortless dying experience.
And, of course, do not forget to mix your dark purple hair dye. Read and follow the instruction of your chosen hair dye brand.
Patch testing is recommended before doing anything to your hair, as you might get an unwanted reaction due to chemical exposure to your skin. It is best to do the patch testing behind the ears or within your inside elbows’ skin because this area is more sensitive than the others.
Why do you need to do a patch test? Paraphenylenediamine, also known as PPD, is a chemical found in almost all hair color products. At the absolute worst, it can trigger a significant allergic response and may damage your skin depending on the severity of the reaction.
Apply a small amount of the dark purple hair dye to the said skin areas, and wait for it to dry for at least 5 to 10 minutes. After it dries or after 10 minutes, there has been no allergic reaction such as reddening of the skin, swelling, difficulty of breathing, and/or nausea, you are safe to proceed to the next step.
This next step is for those who are still unsure whether the shade of dark purple hair dye will suit them or are hesitant about what would be the color result. Get a small number of hair strands and the desired amount of dark purple hair dye, apply it to the hair strands, and leave it on for the next 20 minutes.
If the color result meets your expected outcome, you can now dye your entire hair.
