Types of Hair Dye

Types of Hair Dye

It’s easy to assume that every type of hair dye out there works in the same. In reality, different dyes serve different functions and they shouldn’t be used interchangeably. Here are some of the most common forms of hair dye:

  • Scalp micropigmentation: Rejuvenate SMP describes this as injecting pigment into the scalp to create a natural looking hairline and scalp. This is typically used for shaved heads and combat bald areas and scarring. This is also typically a longer-lasting dye job when compared to a temporary dye or one that rinses out.
  • Temporary hair dye: This only lasts one or two shampoos and is mainly used recreationally, or when someone wants to test out a color on their hair.
  • Semi-permanent hair dye: Lasts 4-6 washes and blends with the existing hair color.
  • Demi-permanent hair dye: This type of dye lasts about a month or two. It’s good for covering up gray areas but needs regular upkeep so that it looks natural.
  • Permanent hair dye: Lasts the longest and provides the most in-depth coverage.
  • Bleach: Bleach is the opposite of a dye, but it still deserves a spot on this list. Whereas dye deposits pigment onto the hair strand, bleach strips away pigment from the strand. This is why dark hair dye fades but highlights and other lightening treatments do not.
  • Henna: Henna is a natural hair dye that is made from crushed plant leaves and is permanent. People who decide to color their hair with henna must use extreme caution – applying any dye or bleach over henna can cause severe damage to the hair and can cause it to fall out.

While I’m no expert and this is by no means an exhaustive list of hair dye types, this list should cover most of the basics.
