Leave-In Hair Density Serum – Overnight Scalp Elixir

Watermans Grow More® Elixir is a leave-in hair loss serum and overnight scalp treatment — a sulphate-free UK hair growth serum that absorbs without grease to support a healthy scalp and fuller, denser-looking hair over time, applied exactly where you need it. Why an Overnight Scalp Serum? Healthy-looking hair starts at the scalp — but a shampoo only acts for the few minutes it's on your head. If you're watching a specific area thin at the hairline, the crown, or a patch that never seems to recover, a few minutes in the shower won't turn it around. A leave-on serum keeps working through the night, exactly where you apply it. Grow More® Elixir is built for targeted, around-the-clock support — no medical treatments, no rinsing, no fuss. What It Does Lightweight, fast-absorbing and non-greasy Supports a refreshed, balanced scalp environment Targets thinning or lower-density areas directly Works overnight, between washes Suitable for all hair types, for men and women Sulphate-free, paraben-free, cruelty-free, and vegan Key Ingredients for Hair Growth Biotin: A building block of keratin — the protein that forms each strand — known for supporting hair strength. Caffeine: Studied for refreshing and energising the scalp at the surface. Rosemary Extract: Researched for supporting scalp comfort and a clean, balanced environment. Niacinamide: Known for improving manageability, shine, and condition. Hydrolysed Lupine Protein (ANAGELINE®): Supports hair-fibre resilience and helps reduce breakage. Argan Oil: Nourishes and helps protect against dryness. How to Use Apply a small amount of the hair loss serum directly to thinning or lower-density areas of the scalp in the evening. Massage in gently and leave on overnight — no need to rinse. Use consistently, ideally alongside Grow Me® Shampoo and Condition Me® Conditioner, for best results. Did You Know? A leave-on serum beats the shower clock. Shampoo only acts for the few minutes it's on the scalp — a leave-in serum keeps supporting the area for hours, which is why it's applied overnight. Target the area, not the whole head. This serum is designed to be applied precisely where density is lower — the hairline, crown or a specific patch. Biotin is a building block of keratin, the protein that forms each strand, which is why it's associated with stronger hair. Caffeine works at the scalp surface to refresh and energise the area around the follicle. Hair grows in cycles, so use it nightly for at least 8–12 weeks before judging results. Hair Loss Serum FAQs How long before I see results?Hair grows on a cycle, so apply nightly for at least 8–12 weeks before judging results. Many notice a calmer, healthier-feeling scalp sooner. Results vary from person to person. Where do I apply it?Directly onto thinning or lower-density areas of the scalp — the hairline, crown, or any patch you want to target. A small amount is enough. Do I rinse it out?No — it's a leave-in. Apply before bed, massage in, and leave overnight. Will it regrow hair on bald areas?Grow More® is a non-medical cosmetic scalp serum: it supports a healthy scalp and the hair you have, and helps reduce breakage. It doesn't treat hereditary or medical hair loss — for that, please see your GP or a trichologist. Can I use it with the shampoo and conditioner?Yes — it's designed to complete the Grow Me® routine. Wash with the shampoo, condition, and use the serum overnight. Is it vegan and cruelty-free?Yes — sulphate-free, paraben-free, palm oil-free, vegan, cruelty-free, and made in the UK.
