The Ordinary's Under-$25 Peptide Serum Boosts Hair Thickness as Experts Back Scalp-Supporting Ingredients

Summary
The Ordinary’s Multi-Peptide Serum is being highlighted as a low-cost option for thinning hair, with users reporting less shedding, thicker hair and visible regrowth after about a month or more of consistent use.
Peptides may help by supporting follicle function, improving scalp circulation, reducing inflammation and extending the hair growth phase, dermatologist Dendy Engelman said, while other specialists also cited benefits for density and scalp health.
The fragrance-free, sulfate-free leave-in serum uses multiple peptide technologies plus plant extracts, and reviewers said its lightweight formula avoids the greasy or sticky feel that often makes hair-loss products hard to keep using.
Engelman said peptide topicals are generally supportive rather than transformative on their own, making them better suited to early thinning or maintenance than advanced hair loss.
For stronger results, she pointed to clinically proven treatments such as minoxidil and in-office PRP, positioning peptide serums as a complementary step rather than a standalone fix.
