My advice would be booking at the venue or confirming what you are booking rather than through app. I booked gel powder infills, assuming this would be infill with gel nail polish which was booked at £20. On completing nails I was told £28. There was was NO other options in the infills and extensions section that mentioned gel and NONE at the cost of £28. So not sure what I would have needed to book it under anyway? As I said staff and nails were nice but I would defiantly be wary in the future
