Hello my flip friends, I needed to tell you all about this GOOPGLOW Restore & Shine Hair Serum by goop. Julia, in her video review, mentioned that she used it before shampooing and it did a really great job restoring her dry, brittle hair. Especially in these colder months, the serum provided a much-needed boost. Julia also mentioned that she was grateful for receiving this product from Flip. If you've also tried this serum, let Julia know in the comments. Overall, based on Julia's experience, the GOOPGLOW Restore & Shine Hair Serum seems to be effective in restoring and adding shine to hair.
