In the year we shopped online more than ever before, internet sales have boomed in 2020 – including at-home beauty treatments. From learning how to trim your split ends to swapping facials for the best face masks, our beauty routines have looked pretty different this year.

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 to Gwyneth Paltrow. Once only an in-salon treatment, the genius formula works to repair broken bonds in damaged hair.
