The ability of aniline derivative tints is limited in which area?

Aniline derivative tints are primarily designed for use on the scalp hair and are particularly effective in coloring natural hair and covering gray hair. However, their use is limited when it comes to application on body hair. This limitation arises because body hair can have different textures, structures, and growth patterns compared to scalp hair, which may result in uneven color absorption or unwanted results. Additionally, the skin on the body is more sensitive and may react differently to the chemicals present in these tints, making them less suitable for that area. This specific aspect underscores the importance of understanding the intended applications and limitations of hair color products in the field of cosmetology.
