well done

I have a couple of clients who stopped going somewhere because they hate having the few stray hairs trimmed. So i always ask and if there is just a couple then I pull them out. There is nothing worse than stubbly eyebrows.

what i do is i pluck them till they are shaped the way i want then i brush them upwards and whatever excess bits i just trim them along the shape. doing tht tells you exactly how much need to trim. it works well for me and u cant tell they have been trimmed but u prevent that odd look when one hair accidently goes up or strays down...very embarrasing!

and i dont kno what to say about whether you should ask your customers or not, im not an expert but i would think the safest option is to ask but explain why you are doing it and how it will enhance the look. i would be kind of shocked if someone just says would u like me to trim ur eyebrows lol...
