DIY Damaged Hair Mask

Came across this video on YouTube for a DIY hair conditioner. I suffer from horrible hair syndrome and i have only found one conditioner that has any effect on it. Unsurprisingly that conditioner is from Wella's professional range and costs a fortune, around £20 - £25 when you buy it out of a salon. I found it much cheaper from lookfantastic.com and hairsupermarket if you ever want to try it.  Therefore i am always on the hunt for some new hair potion. I will definitely  be giving this a try but where to find coconut oil ?

I am getting married in a few months and desperate to keep my hair long but healthy and shiny too! What is your favourite hair treat ?
