1. Temporary Hair Dye:
   • Features: Temporary dyes are typically vibrant and vivid, providing a quick and easy way to experiment with different colors. They don’t penetrate the hair shaft deeply and often wash out after a few shampoos.
   • Benefits: Ideal for short-term color changes or for trying out a new look without committing to a permanent change.
2. Semi-Permanent Hair Dye:
   • Features: This type of dye lasts longer than temporary dyes but still doesn’t penetrate the hair cortex deeply. It gradually fades over several weeks.
   • Benefits: Semi-permanent dyes are less damaging than permanent options and are suitable for those who want a temporary change without the commitment.
3. Demi-Permanent Hair Dye:
   • Features: Demi-permanent dyes last longer than semi-permanent ones and can cover grays to some extent. They penetrate the hair shaft slightly, providing a more substantial color change.
   • Benefits: Suitable for those who want a longer-lasting color without the permanence of traditional dyes. They are often ammonia-free, resulting in less damage to the hair.
4. Permanent Hair Dye:
   • Features: This type of dye provides a long-lasting color change by penetrating the hair cortex. It often contains ammonia and requires a chemical reaction to open the hair cuticle and deposit color.
   • Benefits: Permanent dyes offer a wide range of color options and are effective at covering grays. However, they can be more damaging to the hair due to the chemical processes involved.
5. Natural or Organic Hair Dye:
   • Features: Made from plant-based or natural ingredients, these dyes are often free of ammonia, parabens, and other harsh chemicals.
   • Benefits: Considered a gentler alternative, natural or organic dyes are suitable for individuals with sensitivity to traditional hair dyes. However, they may not provide as intense or long-lasting color.
6. Highlighting and Balayage Kits:
   • Features: These kits are designed specifically for creating highlights or balayage effects. They often come with tools like brushes, caps, or foils for precise application.
   • Benefits: Ideal for adding dimension to hair without fully committing to an all-over color change. They allow for a customized and natural-looking result.
7. Bleach or Lightener:
   • Features: Used to lighten the hair before applying a color or to achieve a blond or pastel shade. Contains strong chemicals like hydrogen peroxide.
   • Benefits: Essential for achieving dramatic color changes, especially when going from dark to light. However, bleach can be damaging to the hair and should be used with caution.

Before choosing a hair dye, it’s crucial to consider factors such as your hair type, condition, and the level of commitment you want with the color change. Additionally, performing a patch test and following the product’s instructions are essential to ensure a successful and safe coloring process.
