Hi,
thought I would give you some info on spray tanning to clear up any confusion, but if any one wants any more in depth info, I have an article I can e mail you that I have written for this months Tanning World, just pm me.
The DHA is the active ingredient in tanning solutions and creams, and generally does not cause any irritation. The higher the percentage, the stronger the developed self tan, but also the risk of irritation. It is therefore not recommended to be any higher than 8%. If a solution has an 8% dha content, one treatment per week is usually enough for a lovely natural looking tan. Some Companies do add other ingredients that boost the dha, but after trying them I have not personally found them to particularly last any longer than ones that do not, this can also affect the price of the solution.
If you are considering spray tanning, you should definitely ask for a demo and what percentage dha is in the solution, a material safety data sheet should be provided and you could also ask for a toxicological report.
Most solutions will give the same developed tan if the dha content is the same, the difference is usually in the instant colour, some are more reddy orange than others.
Be careful when purchasing solutions, as some additives actually break down the dha making it less effective.
Before a treatment, make sure the client has thoroughly exfoliated, especially dry areas and has used a ph balanced body wash. DHA works better at about 4.5 to 5.5 ph value. Ensure they are not wearing make up, perfume, deodourant etc., and remove any jewellery. You can apply a non perfumed lotion to any severe dry areas such as ankles and elbows.
After the treatment, make sure you have given them the correct aftercare advice and that after showering to remove instant colour they use a body lotion/moisturiser to help keep the skin soft and prevent dry flaking patches.
If they wish, 3 days later they may use a light body buff to keep tan even, although this is not always necessary, it depends on their skin type.
Hope this helps.
