Hollywood hair serums benefit the scalp by activating blood vessels and providing nutrients. They also help make the cuticles plumper, resulting in thicker-looking hair. Hill recommends using a serum that combines antioxidant-rich ergothioneine, peptides, and a youth-restoring complex to boost hair density. She also suggests Vegamour’s Gro Serum, which uses fair-trade shea butter to balance the scalp.
