I only discovered coconut oil about 2 years ago & I would never be without again. I use Parachute coconut oil (only because I have bought it when I have been in India) and a 500ml bottle lasts at least 7-8 months.
To liquefy coconut oil, I run the hot tap in my bathroom sink, fill the basin up & then pop the bottle in – it turns to liquid in a minute and stays in liquid form until the water turns tepid.
I use this all over my body as a moisturiser every other day and even on my face when it feels dehydrated. You only need a couple of teaspoons to moisturise your whole body.
Since regularly applying coconut oil, my skin feels more supple and some stretch marks seem "softer" in appearance
I also, use a drop or two of coconut oil to tame/condition frizzy hair especially if the weather is either raining or humid.
