Chemo Weakened My Hair, Extensions Caused Hair Loss On the Sides

I had chemo last year. I didn’t lose my hair but it did thin out, especially at the sides. In december I got hair extensions, after the hairdresser assured me my hair was strong enough. My scalp was slightly red & itchy at the sides and front where the extensions were, but now suddenly my hair at the sides has thinned out even more and I’m almost bald in places. Obviously I’m going to have the extensions removed asap but will my hair grow back? I read recently that if the hair/scalp is traumatised the hair may not grow back. Help!

Hair extensions can produce traction alopecia (hair loss from constant pulling), which may or may not be permanent. Only time will tell. You may need to wait 6-12 months to know if the damage is permanent.
