  1. Charlie

    THE BEST. I’m completely obsessed!

  2. Katie

    I’ve been using this for a couple of weeks now and honestly cannot be without it!! My hair has never been softer and healthier. Great recommendation thank you!

  3. Catherine

    Excellent for fine hair!
    I was using Santa Lucia which I also love however I would say this is more lightweight and especially effective after shampoo and conditioner. I have used it every single day since it arrived! I’ll continue to use Santa Lucia as well, it’s so beautiful, however I am tending to use the Milk on damp hair and then Santa Lucia after blow drying because it really adds shine. The bottle is divine. A truly beautiful brand.

  4. Alannah Brown

    I love this! Gorgeous to use, smells wonderful and makes such a difference to my hair!!!

  5. Maggie

    This is magic! I have loved everything from Roz but this is my new favourite. Love using on damp hair after the shower and it instantly detangles and makes my hair so soft without any hint of greasiness unlike some other leave-ins or oils I’ve tried (even with a small amount!) I can even use this on dry hair and it just hydrates and stops the ends looking dry but in a matte way? Such a fabulous product! Recommend to everyone.
