Semi-permanent dyeing is a real hair coloring, but it is much less long-lasting than the “classic” permanent or long-lasting dyeing, for which the hair must be cut or re-dyed (if you decide to change color, of course).
Semi-permanent dyeing also differs from direct coloring or reflective shampoos, which are the first level of artificial hair coloring.
The latter is formulated in ready-made mixtures that are usually applied to wet and towel-dried hair and last 5-6 shampoos.
Semi-permanent dyes, on the other hand, involve a preparation kit like permanent dyes, but with the difference that the formulations change.
How semi-permanent dye works
Typically, the packages contain the actual pigments and a color activator: both products are mixed at the time of application to obtain the coloring compound (the actual dye).
Why this process? Because although it is relatively short-lived, the semi-permanent dye should color the hair for at least 6 weeks.
This is only possible if the pigments penetrate the hair fiber just enough not to be “washed out” after a few shampoos.
Of course, the activator of semi-permanent dyes has power (in technical jargon, we say, “volume”) decidedly lower than permanent dyes.
That’s why we often refer to other terms such as “tone on tone,” “without oxidation”, and “without ammonia”, although this last expression should not confuse since there are permanent dyes without ammonia (it is the substance that allows the permanent dye to change).

For whom is semi-permanent dye indicated
For those who have their first grey hair but also for those who want to try a new color and are undecided. Or, again, for those who have fragile and sensitized hair, for those who want to add tone-on-tone highlights or make their color more glossy.
It should be noted that, in general, semi-permanent dyes do not lighten your color, unless it is specified on the packaging.
In fact, being devoid of bleaching substances, they are not able to lighten.
They are perfect, moreover, for following all the fashion trends on pastel colors, primary colors (blue, green, purple, etc..), and metallic without the fear of damage … aesthetic!
How long does semi-permanent dyeing last
From 12 to 15 shampoos, depending on the formulations. Generally, the duration is specified on the packaging: some brands prefer to opt for the words “5-6 weeks”.
Baths in the pool and sea may accelerate the gradual disappearance of the color.
Unlike permanent dyes, these lighter dyes do not require much maintenance, such as the use of shampoos and conditioners for colored hair, although it is a good idea to take more care if you notice dryness on the lengths that you did not have before the color.
Natural Remedies To Remove Blue Dye From Hair
These mixtures to remove the dye from the hair in a natural way are the result of folk tradition.
For this reason, there is no scientific evidence regarding their effectiveness and reliability. If you notice an adverse reaction, discontinue use immediately.
Keep in mind that the effects are not immediate and that you have to be very careful when using them, because some ingredients can be very aggressive for thinner hair.
On the other hand, as much as they are considered safe, it is advisable to do a small test before applying them to the entire hair. This way, you can avert any adverse reaction.

Remove the dye with shampoo
Anti-dandruff shampoo, as a rule, has among its components the active ingredient of selenium sulfide. This substance, combined with the whitening effect of bicarbonate, helps to remove hair dye.
However, once again, it should be remembered that this is a gradual process that is not immediately noticeable. You need to use it at least twice a week until you notice an improvement. Also, it is to be avoided if you have brittle hair.
Ingredients
- Anti-dandruff shampoo (as needed)
- 2 tablespoons of baking soda (20 g)
Utensils
- 1 glass container
Preparation
- Calculate the amount of shampoo you usually use to wash your hair.

- Application
- You will apply it to your hair like a regular shampoo.
- Spread it all over your hair, massage, and leave for a few minutes.
- Rinse with plenty of water.
Note: Baking soda is a product that tends to dry the hair a lot, so it should be used in very small amounts and with diluted applications over time. Using it too often in a week to remove the dye could damage the hair.
