What is the difference between room temperature dyeing machine and traditional hair dyeing?

1. Usage temperature: Normal temperature dyeing machine dyes hair at room temperature, while traditional hair dyeing usually requires the use of higher temperatures, such as using hot water, hot towels or steam. This means that the normal temperature dyeing machine is more gentle and comfortable, and less likely to cause damage to the scalp and hair.
2. Time: The normal temperature dyeing machine can complete the hair dyeing process in a short time, usually only 10 to 30 minutes. Traditional hair dyeing, on the other hand, can take longer, sometimes several hours to complete. This makes the room temperature dyeing machine more convenient and faster.
3. Hair dye ingredients: Traditional hair dyes usually contain chemicals such as ammonia or oxidants, which can help the dye penetrate into the hair. However, these ingredients may pose certain health risks, such as irritation to the scalp and hair. In contrast, room-temperature dyeing machines typically use milder hair dye ingredients to reduce potential health hazards.
4. Hair dyeing effect: Room temperature dyeing machine can achieve a more uniform and natural hair dyeing effect. It allows better control of dye penetration and distribution, thereby reducing problems with color unevenness or color difference. Traditional hair dyeing may cause uneven hair color or undyed roots due to uneven distribution of dye.
5. Convenience: The normal temperature dyeing machine is simple to operate and does not require professional technology or experience. It usually comes in the form of a disposable hair mask or hair dye that can be squeezed directly from the package and applied to the hair. Traditional hair dyeing may require more tools and steps, such as stirring the dye, mixing agents, and using a brush or comb to apply the dye evenly to the hair.
6. Color changing ability: Normal temperature dyeing machines can usually achieve color changes from dark hair to light hair. It can help the hair dye penetrate into the hair better, making the hair dye effect more vivid and bright. Traditional hair dyeing may be less effective at changing hair color, especially on dark hair.
7. Durability: Normal temperature dyeing machines can usually last for a long time, usually for 4 to 6 weeks. Traditional hair dyeing may cause the color to fade gradually due to frequent hair washing, sun exposure, and the use of shampoo and hair care products.
