Peptides for hair, brows, and lashes

Scalp density serums and lash boosters use named peptide complexes—here is what Capixyl, Redensyl, and Myristoyl Pentapeptide-17 actually refer to.

Scalp vs lash

Hair-density products often combine multiple trademarked complexes (Capixyl, Procapil, Redensyl) with caffeine or botanicals. Lash serums frequently hinge on myristoyl pentapeptide-17—the ingredient behind many “lash boosting” claims.

Timeline

Expect months, not days. Lash and brow serums need nightly consistency through a full growth cycle. Scalp serums are the same story—slow, incremental density changes.

When to see a pro

Sudden shedding, patchy loss, or scalp pain needs a dermatologist or trichologist—not a peptide serum alone.
