I've had my SNS (on natural nails) treatment done at Donnas for a few months now. Each technician applies them differently but so far I have been happiest with the last application (Donna 2). She was attentive, caring and knowledgeable. The application generally lasts up to 3 weeks which is perfect (sometimes a little less depending on how the SNS is applied I have differing results on chips/breakages etc). I will definitely book with Donna 2 again and hope its the same technician :-)
