The two main types of hair dyes are permanent and semi-permanent. Permanent hair dyes alter the structure of the hair by penetrating the hair shaft and providing a long-lasting color change that remains until new growth appears or the hair is cut. This type of dye typically contains chemicals that lift the cuticle layer of the hair and deposit color deep within.

Semi-permanent hair dyes, on the other hand, coat the outside of the hair shaft and do not penetrate as deeply. They generally last through several shampoos but eventually wash out, making them a good option for those looking for a temporary change or to enhance their natural color without a long-term commitment.

The other choices describe different classifications but do not accurately represent the primary categories of hair dye. For example, temporary hair dye is more of a subset or shorter-lasting option than semi-permanent, while natural and chemical can refer to the origins of the dye ingredients rather than the level of permanence in the color achieved. Organic and synthetic also relates to the source of chemical compounds rather than the dye's lasting power. Thus, recognizing the distinction between permanent and semi-permanent is key to understanding how hair dyes function and how they can be effectively used in practice.
