Liz, early on I started booking my electrolysis on Mondays, with my 'last shave' on Friday mornings. That let me spend my Hairy Weekends in hiding. Not that THAT lasted...
About 6 months in, when I had started full-time life, I found that I occasionally needed to get out on the weekend. Once I joined a church (Unitarian Universalists, a church that matched my belief systems at last!) I found that I had ot be out on Sundays. Jodie, the electrology operator I was seeing, cleared the black hairs out, and tried to keep the 'muzzle' clear of dark hairs in particular. That plus concealer and setting powder helped hide everything from more than a few feet away.
Jodie is clever. She started completely clearing the 'muzzle' after repeated thinning passes as part of each session, and then cleared the jawline, where hairs are visible in silhouette or as the light shines around us. She kept these areas clear as she expanded the thinned out areas on each visit. This helped enormously. The 'muzzle' cleared area has been expanded, and the jawline and neck are mostly cleared now. (Yes, doing 2 two hour sessions each Monday sped this up. Thank goodness!)
All that's really left are 'sideburns', and those are now largely free of dark hairs, and are readily covered by my hairstyle. These sweeps of hair down each cheek are not accidental, ya know!
Soon they will all be gone. Soon, so very soon!
