I know you've asked for electrolysis specifically but for Glasgow I'd defo recommend
https://metroclinic.co.uk Metro Laser Clinic for both laser and electrolysis. Lovely people and do a great job.
If feeling shy or awkward feel free to say Jerrica recommended them to you as an icebreaker. Not on commission or anything lol but can give you an easy in for talking about trans stuff.
Andrew & Gillian know me very well since I started and always leave me feeling really good about myself as their trans experience can be good for an honest analysis of your progress. They are honest but nice if you know what I mean so if you have a weakness they can likely make useful suggestions.
Both are amazing and despite my own shyness I had no problems when it came to letting them get in and about my "delicate" areas. I've been done top to toe and I actually enjoy it as I like their company and being looked after by them.
Ok glowing recommendation done. Any questions feel free to ask.
