Can keto harm hair follicles? After getting an HT I stopped using Keto, I started again 2.5 months post-op and the next day I felt mild irritation/burning on my scalp. I saw visible thinning in the Keto areas (as has happened occasionally before) and now 5 months post-op I am not seeing any growth in the recipient areas. The native hairs that fell out grew back right away, those follicles are undamaged but I'm wondering if the Keto can damage the new, more vulnerable transplanted follicles?
