Clearly you have a bad reaction to the acrylic glue he is using, and you should stop him using it. All the same, I don't think an allergic reaction like that will have killed off your hair follicles in that space of time. My understanding is that that only happens because of traction over time. I think your hair will grow back. I had a hardbond when I first started wearing, and that was my experience. It would help to see a photo though.

Acrylic hardbond and Got2BeGlued are not the only options. There is a huge selection of water-based glues and tapes which will give you 7 - 10 days of hold without the allergic issues. Why not consider one of those instead?
