I had excellent experience with Priti for eyebrow shaping & tinting and eyelash tinting, and can definitely recommend her.
My eyebrows are naturally thin and very light towards the end and I wanted to make them more expressive. She recommended using a tint that is one shade darker than my natural colour, and I'm glad she did - the difference is remarkable in how much stronger & more expressive my brows look (but still natural enough to fit very well with my light brown / ginger hair) :)
