Eyebrow growth

Does anyone know what can help with getting eyebrow hair to grow back after getting it waxed too much ? I got it waxed wayyyy to much and now they’re super thin and the ends just don’t grow back. Is there anything I can do? I hate having to fill them in every day but I feel so ugly and insecure without doing so. 😞

I haven’t waxed for about 3 years now, and I did get some Jamaican black castor oil the end of March to try ... which it deff has helped a little bit but they’re still pretty light and the ends aren’t really growing back

Any tips?
