Sustainability & packaging
+
Recycled & recyclable packaging
Post-consumer recycled materials. FSC-certified outer carton — fully recyclable kerbside.
No filler ingredients — waterless formula
We never dilute with water. Every ingredient earns its place. Less waste, better results.
Fair trade shea butter — Ghana
Sourced from female farmers in Ghana under verified fair trade terms.
Fair trade argan oil — Morocco
From a female-led cooperative in Morocco. Cold-pressed, sustainably harvested.

The Hair Mask works as a deep-treatment system targeting all three bond types simultaneously. The powder component is activated by the serum on contact, creating a fresh, highly potent formula with every use. No preservatives means maximum active concentration — more actives in each application than any preserved alternative.

  • Deep penetration to the hair cortex — not just surface coating
  • Rebuilds all three bond types in one weekly treatment
  • Preservative-free formulation means no compromise on potency
  • Dramatically reduces breakage, shedding, and split ends
  • Restores definition and pattern in curly and coily hair types

Shea Butter (Ghana) — Fair trade from female farmers in northern Ghana. Rich emollient that penetrates deep into the hair cortex, restoring moisture and flexibility.

Argan Oil (Morocco) — Fair trade, cold-pressed. Rebuilds disulfide bonds and adds intense shine.

Aloe Vera Powder — Concentrated aloe locks in hydration and soothes any scalp irritation during treatment.

Amino Acids — Plant-derived amino acids that fill in damage along the hair shaft, smoothing the cuticle and increasing tensile strength.

Baobab Oil — Deeply nourishing, easily absorbed. Restores elasticity and reduces breakage in chemically treated hair.

Step 1: Mix the serum and powder together in the included bowl until fully combined — the mixture will become a rich, creamy texture.

Step 2: Apply generously to freshly washed, towel-dried hair from roots to ends. Work through with fingers.

Step 3: Leave on for 5–20 minutes (longer for more intensive treatment). Cover with a shower cap for deep conditioning.

Step 4: Rinse thoroughly with cool water. Follow with your regular styling routine.

Use once a week or as needed for intensive repair.

Independent clinical trial, December 2023. Participants used the Hair Mask weekly for four weeks alongside their regular NUELE routine.

  • 100% reported softer and smoother hair from first use
  • 100% reported less breakage after the four-week trial
  • 95% said their natural curl or wave pattern was more defined
  • Lab microscopy showed significant improvement in cuticle smoothness and hair porosity

The routine

Use it your way.

01
Apply to dry hair
Mix serum and powder. Apply generously to dry (unwashed) hair from roots to ends. Dry hair absorbs the actives more effectively than wet.
02
Leave for 5–20 minutes
For light maintenance: 5 minutes. For intensive repair after chemical treatment or heavy heat: up to 20 minutes covered with a warm towel.
03
Rinse thoroughly
Rinse completely with warm water. Then shampoo and condition as normal. The mask works before your wash routine, not after.
04
Use weekly
Once a week is ideal for damaged or chemically treated hair. Once every 2 weeks for maintenance. Do not use daily — the actives are highly concentrated.

Lab analysis · Hair strand microscopy

See what changes.

Participants submitted hair strands before and after their trial period for independent laboratory microscopy analysis. What you see below is the structural change — not a filter, not a retouch.

Before
"Severe cuticle lifting and structural fragility — characteristic of chemically treated or heat-damaged hair."
After 2 weeks
"Cuticle sealed, breakage sites filled, shaft darkened indicating strengthened structure — all three bond types reinforced."

The only mask that actually does what it says.
My 4C hair retains moisture for days after a single use. The powder + serum system is more potent than anything pre-made. I've used every deep conditioner out there. This is different — genuinely different.

My bleached hair has never felt this strong.
This mask used weekly for four weeks transformed my ends. The breakage is dramatically less and my hair actually feels structurally sound again. I combine it with the Serum daily.

Takes a little effort — absolutely worth it.
The mixing process takes 2 extra minutes but it's clearly why it works. Hair was noticeably softer and easier to detangle. The clean formula was the deciding factor.
