What is the ruling on a wife's hair falling out due to her daughter pulling it during sleep and breastfeeding, while performing the Hajj pilgrimage?

If her daughter usually pulls her hair, then the wife, keen on preventing that, must cover her head during ihram (definition) or similar states, so that her daughter cannot pull any of her hair. If she falls short in this despite knowing what her daughter will do, then the fidyah (definition) (expiation) becomes obligatory upon her, because the hair in the hand of the muhrim (person in ihram) is like a trust, and he is obligated to pay for its damage. However, if she does not fall short, then nothing is incumbent upon her if her daughter pulls some of her hair, due to her not intentionally committing the prohibited act.
