Hadith prohibits wearing wig when there's a defect

So I heard fatwas from sheikhs and scholars that generally wearing wig is haram but if a women has defect, like hair loss then she can wear it to fix it. For example even in this islamwqa article > With regard to using a wig in a case such as that which you have described, where the woman’s hair has fallen out in a case in which there is no hope of it growing back, we say that in such cases there is nothing wrong with wearing a wig, because in fact it is not done to enhance beauty; rather it is done to remove a defect. Sheikh ibn Uthaymin However I found a Hadith that shows that even in the case when the hair falls out cause of disease. It is still prohibited > حَدَّثَنَا الْحُمَيْدِيُّ، حَدَّثَنَا سُفْيَانُ، حَدَّثَنَا هِشَامٌ، > أَنَّهُ سَمِعَ فَاطِمَةَ بِنْتَ الْمُنْذِرِ، تَقُولُ سَمِعْتُ > أَسْمَاءَ، قَالَتْ سَأَلَتِ امْرَأَةٌ النَّبِيَّ صلى الله عليه وسلم > فَقَالَتْ يَا رَسُولَ اللَّهِ إِنَّ ابْنَتِي أَصَابَتْهَا الْحَصْبَةُ، > فَامَّرَقَ شَعَرُهَا، وَإِنِّي زَوَّجْتُهَا أَفَأَصِلُ فِيهِ فَقَالَ > ‏"‏ لَعَنَ اللَّهُ الْوَاصِلَةَ وَالْمَوْصُولَةَ ‏"‏‏.‏ Narrated > Asma': A woman asked the Prophet (ﷺ) saying, "0 Allah's Messenger (ﷺ) > ! My daughter got measles and her hair fell out. Now that I got her > married, may I let her use false hair?" He said (to her), "Allah has > cursed the lady who lengthens hair artificially and the one who gets > her hair lengthened artificially." Sahih Sahih al-Bukhari, 5941 Then which is the right understanding? And how do you reconcile with the Hadith?
