So I went to book in at my local eyebrow place to have lash extensions this week - but they count fifer me a suitable time. Due to the they offered me the chance to have the done at a suitable time, free, but by someone learning how to do it. Apparently the head eyelash technician from the franchise wil be there to oversee what s going on. What are prs and cons - should I just BO for it and save myself a load of money ?
