To dye or not to dye, that is a question. If you are still puzzling over this problem, you should know some basic information about coloring hair at first. Hair is mostly made of keratin which is colorless and is arranged in overlapping scales in a hair strand, which makes it flexible.
1. Permanent Hair Color
Firstly, apply permanent hair dye to the hair. Then, the ammonia causes the cuticle to ‘open up’ and let the dye in.
Finally, penetrate peroxide (oxidizing agent) into the hair cortex and remove your existing hair color (melanin).
Thus, you have a new color! To close cuticle back to seal the new color in, you can try conditioner.
If you want to bleach or lighten hair, you can try this process.
2. Semi-permanent Hair Color
It is a gentle coloring process, and can last 4-6 weeks. Semi-permanent dye doesn’t have ammonia or peroxide. Add tiny color molecules to hair’s cuticle without dramatically changing the original hair color. But, they eventually escape the cuticle and the color fades out after several shampoos, since these molecules are small.
3. Demi-permanent Hair Color
This dye doesn’t contain ammonia, but it has a little bit of peroxide.
This type of hair color will coat each hair strand with color, and creates larger molecules in the hair cortex. It lasts about 8-12 weeks.
It is recommended to choose semi-permanent hair dye, as it is the least damaging to your hair. Conditioners indeed can seal the cuticle after the coloring process is finished. But, the hair strand will not revert to the condition it was in originally without your help.
