Is this hair-health multivitamin and mineral tablet safe for women to take?

Yes, this type of supplement, with biotin, zinc, selenium and various amino acids, is generally suitable for women too and is often used to support hair strength when nutrition is the underlying issue. It's just worth ruling out other causes like thyroid function, iron levels or hormonal changes, since those are common in women and won't necessarily respond to a supplement alone. Your doctor can help pinpoint the actual cause before you commit to it long-term.
