A solution with both DHA and Erythrulose in it is particularly suited to Redheads. The combination of the two tanning ingredients gives a better depth of colour for fairer skins, as the Erythrulose adds a softer level of warmth to the tones provided by the DHA.
The orange look comes from using too much or too darker solution, so opt for a light good quality solution, and you won't have any problems. I have several clients with reddish tones, from Strawberry blonde right the way through to full on redhead and they always look great!
