Very very cheap hair mask

Hello All, I originally bought a large bottle of Tesco Value hair conditioner (31p for 500ml) as a suds killer for my vax. But decided in one of my madder moments to give it a go as a hair mask. I have very long (and very dry) hair so trying to keep it looking nice is a constant battle. Anyway all I did was wet my hair apply good dollp of conditioner and wrap in a warm towel for 20 minutes then rinse out and dry as normal. Hey presto, lovely soft hair! Probably enough in the Tesco Value bottle to do this another 30 or 40 times. So not even a penny per application!
