TRIED, TESTED, TRUSTED

At the GHI, our beauty and haircare labs have state-of-the-art equipment to assess product claims, meaning our reviews have a scientific basis. Plus, to date, more than 7,000 women have taken part in our consumer trials. Products are blinded (evidence of brand is hidden) so tests are fair.
