I really love using 100% argan oil on my hair. My hair is fairly porous as I lighten it & it really soaks up the argan oil on the ends. I find it light & so doesn't weigh my hair down. I've definitely had less split ends since using it. At the moment I'm using The Ordinary argan oil, I think it's about £7, which is such a bargain as it lasts ages.
@MiaL I would recommd Uniq One all in one hair treatment coconut spray. Its a great spray and can be used as a leave in conditioner. I won't wash my hair if I know i don't have it with me 😊 Last ages, you don't need a lot and if your hair gets knotted easy it's a great detangler.
