I am very particular about my brows (I have naturally blonde hair and my brows are practically white). So it's really easy for someone to over wax them. In all the years I've searched for people who know how to wax them properly, there are only two people who know how to do them right and one of them is Olga. She is SO amazing at what she does and I'm so so happy I found her. Her prices are a little steep but honestly it's worth it to finally have someone who knows what they are doing. She even shades/colors them in properly (people ALWAYS tend to do them too dark and uneven) and takes the time to explain how to do it! It's seriously so hard to find someone who knows what they are doing, especially when it comes to my brows. The only thing I will say is that I had referred my sister who is now a loyal costumer as well, and she doesn't have a referral (or loyalty) program. But I guess when you're so good you don't really need it! Lol
