❖ Question:
What is the ruling on using hair dyes available in the market today? Some people claim that these dyes form a layer like nail polish, which prevents valid wudu. Is this correct?
❖ Answer:
The impact of hair dyes on the validity of
wudu (ablution) depends on
how the dye affects the hair. There are two scenarios:
① Formation of a Coating (Like Nail Polish)
If the dye
forms a layer on the hair similar to nail polish that
prevents water from reaching the hair, then
wudu and ghusl (ritual bath) will
not be valid. It is a requirement for wudu and ghusl that water must reach
every part of the body, including the hair.
② Only Coloring the Hair (Like Henna)
If the dye
does not form a layer, but merely
colors the hair like henna does, and
does not obstruct water from reaching the hair, then it will
not affect the validity of wudu or ghusl. In this case, the wudu is valid.
❖ Summary:
If the dye
creates a barrier on the hair that
prevents water from reaching it, then wudu and ghusl are
invalid. However, if the dye
only imparts color without forming a barrier, then there is
no impact on wudu or ghusl, and using such dye is
permissible.
