I have a few like that. They've lasted me 6 years that weak. Be extra careful with washing around that lock. Try not to scrub it too hard. Time will help heal it. Don't mess with it trying to fix it for a while. I mean months and months. If it is still that weak in 6 months, you can get some hemp/embroidery thread and tie it to the hairs around it.
Locks generally seem weaker at the roots because the hair isn't locked up yet. So in a few months, it may fix itself as the hairs at the root mat up and lock together
