About this product
A leave-in scalp serum from The Ordinary that uses a blend of peptides and caffeine to support the look of fuller, denser-appearing hair, not a treatment for pattern hair loss.

The Guru Index verdict
Mixed
~Mixed · 63%What the gurus are saying
Gurus overwhelmingly praise this serum as a hydrating scalp treatment, especially for winter dryness and flakiness, with many repurchasing repeatedly. The consensus is that it excels at moisture and scalp comfort rather than dramatic hair growth. A few reviewers saw no significant density results or didn't notice changes, and one noted potential irritation from castor oil and polysorbate 20 for sensitive scalps. One reviewer flagged that ingredient concentrations aren't disclosed, limiting confidence in efficacy claims.
