Thank you so much for your review, Katrina. I am hoping to be able to assist you with the use of this product so you can enjoy it and get the benefits from using it :)
The oil is designed to sit 'on' your skin to protect it rather than soak 'in' like a moisturiser would, so make sure you apply your serums and moisturiser first and then the 'Repairing Facial Oil' as your final step.
As for the stickiness and transfer to your pillow, you only need to apply 2-3 drops to your entire face and neck as a little goes a long way.
Hope that helps :) You can definitely use it in your hair too and it makes a great cuticle/nail oil.
