Wiping over the head dyed with henna

The questioner:
The Shaykh comes and asks: If a woman covers her head, how does she apply the dye to it? And likewise for her nose.

The Shaykh:
What is natural?

The questioner:
As for the woman who covers her head, she does this; how does she wipe over it? And likewise for the eyebrows and the eyelashes.

The Shaykh:
There is no objection to applying the dye and wiping over it, or putting henna on it and wiping over it. There is no objection because this is not considered one of the barriers that prevent the oil from reaching the skin; it is not a barrier. The henna gives off a slight amount, and it is possible that when water comes upon it, it will penetrate to the head. It is not solidified; it is not solid. So there is no objection, neither to the henna nor to the oil. Yes.

Another questioner:
My dear.

The Shaykh:
Even if it is dry, when water comes to it, it penetrates through it and goes down to what is underneath. It does not prevent it at all. It is dry, and you put it on and pour water over it; the water burns the henna. Yes.
