I just about never name change on MN, but on this occasion feel I should as, sadly, my DS has a 'friend' whose weird mum sort of stalked me on here, 2 years ago. I am a very long term MNetter!
Anyway, DS, 18, is developing a bit of a monobrow which he hates. He struggles with his appearance, despite having the strongest, most luxuriant, impressive hair in the family. We call it The Family Hairloom. 
His eyebrows are pretty conventional, tho they do extend down to the fleshy bit below (the bit your 18 year old DDs would have had fastidiously removed at least 3 years ago, on a monthly basis!) ; but he has an, as yet, blond, monobrow.
He wants it gone. Plus some 'shaping'.
Who, professionally, would do that for him? I could (and would), but in a small way, I sort of think that having 'mum do it in secret at home'- takes away from the: 'Nah, bit of me I wanna deal with, via appointment at an appropriate salon' that adult men have to deal with. Add to that, he has just really subtly hinted that he wants his undercarriage 'cleaned up'.
Now, this in no way upsets, shocks or anything else's me. Girls do it all the time. I remember my first 'encounter' with this, 20 years ago, abroad (not that that's relevant! But can't type the Antipppodeez in case stalker picks up...) where a toddler run around in a park, ended where one mum had to go pick up her DH from his back, crack and sack...! NO idea, til then! But I know now, and fully appreciate why any bloke might want to clear up hair from places he doesn't want it, just like many women.
So, my take away question is- bearing in mind we're currently just talking brows, what does he search to find somewhere where he won't be sitting in the middle of the local mall, getting threaded as his 'mates' stroll by?
And, drilling down, as it were .. how does he search more 'intimate' waxing, should he choose to do it?
