How long does Koleston hair dye last?
When you choose to dye your hair, whether for the first time or after a long time, you can apply the dye to all of your hair at once and leave it for 40 minutes. Taking care of your hair after dyeing is essential to maintain its luster and beauty. If you use “Wella Koleston” dye, use the attached conditioner for better care, and don’t forget to renew the color’s luster with the activator after two weeks. After a month, you will notice that your hair has regained its health and color.
It is worth noting that using a hair dryer can speed up and improve the results of the dye, but care must be taken not to leave the dye on the hair all night to avoid damage.
Choosing the type of dye determines how long it will stay on your hair; temporary dyes last for about 12 washes and do not affect the original color of the hair or cause graying, while semi-permanent dyes last for about 26 washes and contain peroxide without ammonia. Permanent dyes last until the roots grow in and require re-dyeing after six weeks.

Important instructions before dyeing hair using Koleston Naturals Medium Brown dye
1- Avoid applying dye to your hair while it is wet, and it is best to avoid washing your hair for three days before dyeing it.
2- If your hair is treated with henna, wait 5 to 6 months before dyeing it. The reason is that henna forms layers on the hair that prevent the dye from penetrating evenly, resulting in inconsistent colors.
3- It is forbidden to use this dye for eyebrows.
4- It is important to conduct a sensitivity test for the product 48 hours before applying the dye to the hair.
5- To ensure you get the results you want, do a test on a strand of hair before dyeing the entire hair.
How to use the Coleston formula
To ensure the perfect result when dyeing your hair, you must first make sure that your hair is dry and free of any oils or creams. Use gloves and mix the hair dye with the developer solution included with it. Make sure to close the container and shake it well to mix the ingredients. Then, pour the mixture into a bowl for easy use.
Start by dividing your hair into four sections and apply the dye starting from the ends and working your way up to the roots. Once your hair is completely covered, cover it with a plastic cap and leave it for 30 minutes. Later, wash your hair with water only and use the conditioner provided with the dye before washing it again with water.
Avoid using shampoo for 24 hours after dyeing to maintain color stability. The color can be stimulated and renewed after two weeks using the color activation sachet included in the package, by combing the hair with the activator and leaving it for 10 minutes before washing it.
Koleston dye damage
Hair dyes like Koleston come with their advantages of changing hair color and giving it a new look, but caution must be taken because they have potential harms. Scientific studies have shown the risk of cancer when using these dyes repeatedly. Koleston dye is known to contain a high percentage of ammonia, which increases its strength and makes it more difficult to remove if you do not like the color, and can lead to allergic reactions ranging from mild to severe.
It is recommended to avoid using hair dye in case of hair problems, during pregnancy and breastfeeding, and not to use it on the hair of children under the age of 16. It is also warned against using it on eyebrows and eyelashes to avoid health risks. To test for sensitivity to the dye, it is recommended to apply a small amount of it to a hidden area of the skin and wait half an hour to see if there are any reactions such as redness or itching, which indicates an allergy, and the absence of any reaction means that the dye is safe to use.
