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

Best Overnight Scalp Oil

Castor Oil — Rich in ricinoleic acid, promotes scalp circulation and supports hair follicle health. The backbone of the overnight repair system.

Argan Oil (Morocco) — Fair trade. Penetrates the hair shaft while you sleep to rebuild disulfide and ionic bonds.

Aloe Vera — Deeply calming and hydrating for the scalp. Reduces inflammation and dryness at the root.

Lavender (Naturally Derived) — Antimicrobial and soothing. Provides a gentle natural scent and supports scalp health without synthetic fragrance compounds.

Jojoba Oil — Balances scalp oil production overnight and prevents the overproduction that leads to buildup.

Step 1: Apply 4–6 drops to your fingertips.

Step 2: Section hair and massage directly into the scalp with gentle circular motions for 1–2 minutes.

Step 3: Work any remaining product through the hair lengths.

Step 4: Leave overnight. No rinsing required — the formula absorbs fully by morning.

Use 2–3 times per week or nightly for intensive scalp restoration.

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.
