Split ends are a structural failure, not a styling problem. Once the hair fibre splits at the tip, the only permanent solution is a cut. What a serum can do — and what MELU Serum does measurably — is smooth and seal the visible split, reinforce the weakened fibre around it to slow further splitting, and reduce the mechanical stress during brushing and styling that causes new splits to form. It doesn't fix what's already broken. It protects what's left and makes the damage less visible in the meantime.

MELU Serum is a leave-in cream serum built around Regenerative Organic Certified™ Black Chickpea Extract (Hydrolyzed Cicer Seed Extract) — sourced from Mr. Gabriele Colla's farm in Parma, Italy. The same extract that powers the MELU Anti-Breakage Spray — rich in polysaccharides and antioxidants — works differently here due to the serum format and higher concentration. Where the Spray deposits a protective film pre-styling across the full length of the hair, the Serum works as a targeted treatment on lengths and ends, delivering a richer, more substantive coating that physically smooths and seals visible split ends while reinforcing the weakened fibre structure around them.

Behentrimonium Methosulfate is the primary conditioning agent — a gentler, biodegradable alternative to Behentrimonium Chloride that provides exceptional slip, detangling, and cuticle-smoothing without the charge buildup that can cause stiffness over time. Orbignya Oleifera Seed Oil (Babassu Oil) provides lightweight emollient conditioning with high lauric acid content that absorbs into the hair shaft rather than coating the surface — delivering softness, manageability, and moisture without the heaviness that weighs down long hair. Simmondsia Chinensis (Jojoba) Seed Oil closely mimics the hair's natural sebum and absorbs without residue, adding elasticity and shine to compromised ends. Lauroyl Lysine (an amino acid — fatty acid complex) provides the characteristic velvety feel of the serum and improves the surface slip that allows the formula to glide through lengths without pulling. Sclerotium Gum adds a lightweight film-forming hold that keeps the serum's protective complex in place through styling and drying. Benzotriazolyl Dodecyl P-Cresol provides UV protection at the hair shaft level, shielding the already-damaged fibre from additional photo-oxidative stress. Ethyl Oleate (olive-derived lightweight ester) delivers additional cuticle-smoothing and shine enhancement at the ends.

The formula's overnight application mode is a meaningful differentiator: applied to dry hair before bed, the serum works without heat or styling disruption, nourishing lengths and ends through the night and providing protection against friction damage from movement during sleep — one of the underappreciated causes of tip degradation on long hair.

Efficacy verified through independent clinical testing:

• Visibly reduces split ends by 32.5% after just one use — clinical test on 20 volunteers
• Reduces breakage during brushing by 39% — clinical test on 20 participants with split ends and brittle hair after 4 weeks of use of the MELU system (Shampoo, Conditioner, and Serum)
• 90% of users noticed a visible improvement in the appearance of split ends — self-assessment by 20 participants after 4 weeks of MELU system use

96.6% naturally derived. Vegan.

Metro Vancouver note: Coastal humidity combined with outdoor UV exposure accelerates oxidative stress on already-damaged ends. The Benzotriazolyl Dodecyl P-Cresol UV filter in this formula provides an additional protective layer for long hair worn outdoors in Metro Vancouver's environment year-round.

Who It's For Long or very damaged hair with visible split ends — particularly hair that has been bleached, coloured, heat-styled frequently, or chemically processed. Works on all textures. Fine hair should use 3 pumps maximum to avoid over-softening at the root; apply to lengths and ends only. The overnight application mode makes this well-suited to anyone building a repair routine who wants to maximise results without adding extra steps to their morning routine.

Key Ingredients

• Hydrolyzed Cicer Seed Extract (ROC™ Black Chickpea, Parma, Italy) — Polysaccharides seal visible split ends and create a protective film against breakage; antioxidants preserve hair strength and structure
• Behentrimonium Methosulfate — Gentle biodegradable conditioning agent; exceptional slip, detangling, and cuticle smoothing without charge buildup
• Orbignya Oleifera Seed Oil (Babassu) — Lightweight tropical emollient with high lauric acid; absorbs into the shaft for softness and manageability without surface weight
• Simmondsia Chinensis (Jojoba) Seed Oil — Sebum-mimicking emollient; adds elasticity and shine to compromised ends without residue
• Lauroyl Lysine — Amino acid–fatty acid complex; provides the serum's velvety feel and surface slip through lengths
• Benzotriazolyl Dodecyl P-Cresol — UV filter at the hair shaft level; protects damaged ends from additional photo-oxidative stress
• Sclerotium Gum — Lightweight film-forming polysaccharide; holds the protective complex in place through styling and drying

HOW TO USE: 

Standard application (daily pre-styling): Apply 3–5 pumps to towel-dried hair after washing. Do not rinse. Dry and style as desired. Apply to lengths and ends only on fine hair.

Overnight application (intensive repair): Apply to dry hair before bedtime. Leave in overnight without rinsing. Proceed with usual styling in the morning without washing. Nourishes and repairs lengths and ends through the night; provides protection against friction damage during sleep.

Layering tip: Apply MELU Serum to lengths and ends first, then follow with MELU Anti-Breakage Spray → across the full length for combined split-end reduction and heat protection up to 230°C.
