The ruling on a woman wiping over her hair after applying a hair setting agent

Question:
Also, a questioner asks: One of the sisters says: Is it permissible to apply spray, which is a substance for setting hair, like water mist, but after spraying it becomes dry and is applied to set the hair? He asks: Does applying this substance to the hair act as a barrier, thereby invalidating her wudu' (ablution) unless it is washed off? And in this case, can the woman pass her fingers through her hair to wipe small parts of it so as not to ruin her hair, which happens with many women, or is it necessary to wipe over the entire head?

Answer:
What is applied to a woman's head, if it solidifies and prevents water from reaching the hair, is not permissible, and it must be removed for wudu' (ablution) and ghusl (full ritual bath). However, if it does not solidify and does not prevent water from penetrating the hair when wiped over or washed, there is no harm in it. Yes.
