Leave-In Hair Density Serum – Overnight Scalp Elixir

While you sleep, your hair should be working. A shampoo only works for the few minutes it's on your head. Grow More® Elixir is the high-strength leave-in step for men and women that keeps working all night, applied straight onto the scalp exactly where you need it.

Important: this is a targeted scalp treatment, not an all-over hair spray. You don't spray it through your hair. You apply it directly onto the problem areas of your scalp. Around 90% of our customers put it on their scalp before bed and leave it in overnight, with no need to wash out.

Why Grow More®?

• ✔ The problem it solves: a routine that stops when you rinse. This stays on the scalp and works between washes, all night long.
• ✔ Who it's for: men and women alike. You apply it at night straight onto the problem areas of your scalp: the hairline, the crown, or anywhere thinning. It's ideal for anyone who doesn't want to wash their hair 4 to 5 times a week but still wants the full results of the Grow Me® routine.
• ✔ Why it's better: a targeted, non-greasy leave-in you apply directly onto the scalp, not sprayed through your hair. No rinsing, no fuss, no residue.
• ✔ The result you'll get: a re-energised scalp and the optimal environment for healthy hair growth, with fuller, denser-looking areas over 12 weeks of nightly use. Results vary from person to person.

What It Does For You

• Keeps your routine working between washes. Can't wash 4 to 5 times a week? Apply this to your scalp at night and it still gets its daily care.
• Targets the areas you choose. Precision care aimed straight at the exact spots you want to improve, instead of diluting the effort across your whole head.
• Re-energises your scalp. It helps energise the scalp by supporting healthy circulation around the hair follicles, creating an environment where follicles can function at their best.
• Fits into any life. Lightweight, fast-absorbing and non-greasy. Apply before bed and forget about it, no need to wash out.

The toothbrush trick: for faster results, keep the bottle next to your toothbrush and apply it to your scalp every night on the areas you want to improve. It becomes as automatic as brushing your teeth, and consistency is what brings results.

Grow More® is a non-medical, cosmetic scalp serum. It cares for the scalp and the hair you have. It does not treat hereditary or medical hair loss.

Grow More® Elixir FAQs

How do I apply it?

Onto the scalp, not through your hair. This isn't a spray-all-over serum: you target it directly onto the problem areas of your scalp, the hairline, the crown, or any patch you want to work on. A small amount is enough. Massage in gently and leave overnight. Around 90% of our customers apply it before bed and leave it in, with no need to wash out.

How long before I see results?

Hair grows on a cycle, so apply Grow More® nightly for at least 8 to 12 weeks before judging results. Many notice a calmer, healthier-feeling scalp much sooner. We recommend you choose the subscription that will save you money in the long run. You need to use this product for at least three months. But why stop using something that actually works? Results vary from person to person.

How does it work on the scalp?

It helps energise the scalp by supporting healthy circulation around the hair follicles. Improved scalp circulation helps create an environment where follicles can function at their best. Our carefully selected ingredients work together to nourish the scalp and create the optimal conditions for healthier, stronger-looking hair.

Will it make my hair greasy?

No. It's lightweight, fast-absorbing and non-greasy, designed to disappear into the scalp and get to work.

Is it vegan and cruelty-free?

Yes. Sulphate-free, paraben-free, palm oil-free, vegan, cruelty-free, and made in the UK.
