Q. May a married woman that totally lost her hair due to radiation treatment, wear a wig which is attached with glue and remains affixed to her scalp for 30 days, at which time the glue is reapplied and she continues to wear it month after month. Is this considered as a normal sheitel or does she have to cover this hair?
If she has new hair implants from an identical twin or from other parts of her body, does she have to cover her hair?

A. Horav Shlomo Millers Shlita opinion is that in the first case she should treat that wig like any other
common sheitl and depending on the minhag she usually keeps, she should behave accordingly. However, she does have to remove the wig before immersing in a mikva.
On the second question, you would consider viable hair implants like natural hair and she has to cover it.
