Oil for dry, brittle hair

I've been using a lot of Mise en Scène oil so far, but it feels like I'm not making any progress.

It was fine when my hair was short, but now that it's long, the dryness bothers me more...

Could you possibly recommend an oil that is good for dry, brittle hair?

Please recommend something with a reasonable price.

Mise-en-scène products are good too.
