Try
L'Oréal Keratase Fluid Intergral SPF10 from L'Oréal hairdressers,
Rausch also make one with green tea in it and you can get that from pharmacies. Actually many pharmacies should stock a suitable product, especially the sunscreens from La
Roche-Posay Antihelios spray (I love their gel SPF, it is fantastic and does not sweat off). Good luck.
