Don't know if it's quite the same but Boots have this :-

Might be better than nothing

Have had a mooch on the Boots website and they sell Argan Oil which my friend who has long frizzy hair swears by http://www.boots.com/en/Argan-Oil-Hair-Treatment-100ml_1222352/

Not sure if the airport will have it - suppose it may depend on the size of the shop but you may have time to nip to your local store.

Oo might have a nosey at the argan oil - fingers crossed they got some - probably get something in resort if not. Had my whole day all planned out - still nowhere near finished packing, house work etc

thanks for the replies

Good luck with the hair product and have a great holiday
