If you have been a frequent shaver previously (even if you have let your hair grow for a few weeks before your sugaring or waxing treatment), shaving can cause hair re-growth to be uneven, in which some hairs can be too short to be removed with wax or sugaring gel & may result in the appearance of stubble after your first treatment. Ideally, all of your hairs should lay flat on your skin to achieve the best results; so some of these shorter hairs may not be removed with wax or sugaring gel the first time. Please have patience & let those shorter stubbles grow (no shaving between treatments!) so that your second treatment will have even smoother results!
