Choosing a spray tan solution is about more than picking the darkest bottle. A great result depends on the client’s starting skin tone, preferred finish, preparation and how carefully the solution is applied.
What is DHA in spray tan?
Dihydroxyacetone (DHA) is the cosmetic tanning ingredient that reacts with compounds in the outer layer of skin to produce a temporary bronzed appearance. The shade develops over time and fades as surface skin cells naturally shed. The percentage of DHA influences the depth of the result, but undertone, formulation and application technique also matter.
Choosing 8%, 10%, 12% or 14% DHA
For a subtle introduction, 8% can be a helpful starting point; 10% suits clients seeking a more noticeable everyday bronze; 12% may be considered for a deeper result; and 14% is designed for a richer finish. These are starting points, not universal matches to particular skin types. Always consider the client's preferences and carry out a consultation.
Duo Spray Tanning Solution is available in 8%, 10%, 12% and 14% options, making it a practical range for therapists offering more than one depth of tan.
Don't forget undertone
Two clients using the same DHA strength may see different-looking results. Natural skin colour, undertones and the cosmetic guide colour all affect perception. Ask whether a client wants a light golden glow, a warm bronze or a deeper appearance, and keep notes about previous results so future appointments are easier to tailor.
Match the formula to the appointment
For an appointment with a conventional development window, a classic professional solution may be suitable. For clients who need to rinse sooner, consider Express Spray Tanning Solution, while checking its specific rinse instructions. A quick rinse never means the final colour appears instantly.
Application matters as much as the solution
Start with clean, dry skin; ensure exfoliation is done in advance; protect particularly dry areas; and apply an even, controlled layer using professional equipment and appropriate ventilation. Avoid over-spraying elbows, knees, hands and feet. Follow the product's own guidance for rinse time and aftercare.
Helping the tan fade evenly
Explain that moisturising, avoiding aggressive exfoliation and patting skin dry after washing can help maintain a more even-looking finish. No DHA tan lasts permanently, and repeated friction or very dry skin can cause patches.
If you need a closer look at formulation strength, we explain the differences between 8%, 10%, 12% and 14% DHA separately. Salon owners comparing suppliers can also review choosing professional spray tan formulas.
Build a consistent salon menu
A simple menu of light, medium, deep and express options makes consultations clearer for clients. Keep records of formula, shade, application and client feedback. You can compare the professional spray tanning range to decide which options belong on your treatment menu.
A practical way to choose a spray tan formula
Start with the result the customer wants, not just the number printed on a bottle. Ask about preferred depth, previous self-tanning experience, skin sensitivity, undertones, the timing of their event and when they can take their first rinse. Explain that a photograph of a tan on someone else cannot guarantee the same result on their skin.
| Client need | What to consider |
|---|---|
| First appointment or subtle result | Use a conservative shade choice and agree the desired finish in advance. |
| Deeper bronze | Consider a stronger formula only if appropriate to the client and the manufacturer’s instructions. |
| Limited time before rinsing | Discuss an express formula and its specific rinse-time directions. |
| Dry or uneven skin | Address preparation and expectations; a stronger DHA percentage will not correct poor preparation. |
Undertone, guide colour and developed colour are different
Guide colour makes it easier to see where the mist has been applied. It may rinse away, leaving the DHA reaction to continue developing. The final shade can vary with skin condition, application quantity and the formula’s other ingredients. Olive, warm and golden descriptions help describe the intended cosmetic appearance, not a guaranteed match for every skin tone.
How to test a new spray tanning solution in your salon
Before switching your standard menu, test the new solution using the supplier’s instructions and your normal equipment. Record nozzle settings, application technique, colour at the correct development point, first-rinse experience and appearance over the next several days. Keep the lighting and photographs consistent, with client consent, so comparisons are useful.
Sunjunkie’s Duo Spray Tanning Solution currently offers selectable 8%, 10%, 12% and 14% options. For the detailed meaning and limitations of those percentages, see the separate DHA strength comparison. This guide focuses instead on deciding which complete formula and service style suit the appointment.
What to confirm before you book a client
Check that the solution is appropriate for your equipment, that its current application and rinse instructions are available, and that you can give clear pre- and aftercare guidance. Ask about previous reactions or current skin irritation and avoid application to broken skin. Protect against unnecessary inhalation or contact with eyes and mucous membranes in line with supplier and professional safety advice.
