If you get the right spray tan you'll never look back. Look for a brand which offers differing DHA %'s like Unreal. They have a selection from 6% through to a dark 12%. You can have them mixed by your therapist to make a "bespoke" colour for your skin tone. They also do an after care range which you can top up yourself if you want. They are without doubt the best brand and they use organic Ecocert DHA, no smell and very natural looking. I know they're not so well known but they are catching on check their website
