On the GN Daily page there's a featured about thinning eyebrows and a link to forum discussions. This link took me to a defunct thread and suggested starting a new one, so here goes!
Of the many remedies for thinning eyebrows, one was growth serums. I've used these (Rapidbrow) and they really work but as soon as you stop using them the new hair disappears and you're back to square one! (Same applies to eyelash serums and, probably, scalp treatments for hair loss.) They are not cheap so it's worth knowing.
