Lookfantastic has now shared with woman&home its top 10 best selling beauty products in both the UK and the US, and it makes for very interesting reading indeed. 

The number one best seller on the e-tailer in the UK? None other than the Olaplex No 3 Treatment. So good is this little bottle of repairing elixir that it's loved by celebrities all around the world, from Jennifer Lopez (opens in new tab) to Gwyneth Paltrow (opens in new tab). Once only an in-salon treatment, the genius formula works to repair broken bonds in damaged hair.
