You are right; proper skin prep is essential for best spray results; clients should:
- Exfoliate regularly and a day before the spray with a oil free product to remove dead skin cells.
- Shave or wax a day before the spray.
- Shower a few hours before the spray.
- Not apply makeup, deodorant, perfume or oil based lotions after showering.
- Moisturize regularly and several hours before the spray with a water based moisturizer.
- Wear dark, loose fitting clothing to the spray appointment.
If they a getting a first time spray for a special occasion they might consider doing a trial spray well in advance to preview prep and results.
You should stock / sell the skincare products they will need for prep and for maintenance of their tan; those are not just an important profit area but quality products add to customer satisfaction.
