June is great - a lovely person and very good at eyelash extensions and eyebrow tinting. I've had mine for a week now, and they still look as if I'd just had them done. I'd definitely go back for an infill when necessary. The makeup artist in my photo shoot told me that they were among the best eyelash extensions she'd seen.
The ambience of the salon is a bit frantic, but that didn't really bother me. I live in Camden, but would still go back to Brixton to have June do my lashes again.
