The Nighttime Scalp Serum works on two levels simultaneously: soothing and restoring the scalp environment while feeding nutrients into the hair shaft overnight. Healthy hair starts at a healthy scalp — this formula addresses both.

  • Soothes irritation, dryness, and inflammation at the scalp
  • Feeds nutrients into the hair shaft during overnight absorption
  • Castor oil promotes circulation and supports healthy growth
  • Lavender provides antimicrobial benefits without synthetic fragrance
  • Non-greasy — absorbs fully by morning with no residue

    The routine

    Use it your way.

    01
    Apply to clean scalp
    Apply 4–6 drops directly to scalp sections before bed. Use fingertips to distribute across the full scalp, not just the hair.
    02
    Massage for 2 minutes
    Massage in circular motions. This stimulates microcirculation and ensures the castor and argan actives penetrate to the follicle level.
    03
    No rinse needed
    Leave overnight. The formula absorbs completely and won't transfer to pillowcases. Use a silk pillowcase for extra protection.
    04
    Use 2–3 nights per week
    Consistency drives results. Most users notice improved scalp condition in 2 weeks and measurable growth improvement at 6–8 weeks.
