HC BLUE NO. 18

Description

HC Blue No. 18 is a semi-permanent hair dye compound used in various hair coloring products. This synthetic colorant belongs to the family of HC (Hair Color) dyes and imparts a blue hue to hair. It is particularly effective in creating vibrant blue shades or as a component in darker, cool-toned hair colors.

The chemical structure of HC Blue No. 18 allows it to penetrate the hair shaft, providing longer-lasting color compared to temporary dyes. It is often used in combination with other HC dyes to achieve a wide range of color results. This dye is suitable for both professional salon use and at-home hair coloring products.

HC Blue No. 18 is generally considered safe for use in hair dyes when applied according to manufacturer instructions. However, as with all hair dyes, it may cause allergic reactions in some individuals. Patch testing is recommended before full application. This colorant gradually fades with washing, typically lasting 4-6 weeks depending on hair type and care routine. It is important to note that HC Blue No. 18 may not be suitable for use on very light or pre-lightened hair, as it can result in uneven or overly intense color results.
