Ingredients
LINIGROW Peptide Hair Growth Serum is built around peptides — short chains of amino acids widely used in modern skincare — carried in a light serum base designed for the scalp rather than the hair shaft.
The base is deliberately lightweight. It is made to sink into the skin of the scalp and leave no oily film behind, which is what allows the serum to be used daily without weighing hair down.
Because it is a leave-in product that is never rinsed out, every part of the formula is chosen to sit comfortably on the scalp between washes.

What it is for
Made for the scalp, not the lengths
Shampoo cleans it, conditioner avoids it, and most treatments are designed for the hair you can see. The scalp — the skin your hair actually grows from — usually gets nothing of its own.
LINIGROW is the step that fills that gap. It is applied along the partings, massaged into the skin and left in, so the product reaches the roots rather than coating the ends.
- Applied directly to the scalp, section by section
- Light enough to use on clean or dry hair
- Leave-in — no rinsing, no wash day to plan around
- Works alongside whatever you already use on your lengths
Why it works the way it does
Built around four simple decisions
A serum, not an oil
The texture is light on purpose. It absorbs rather than sitting on top, so hair still feels like hair afterwards.
Peptides at the centre
Peptides are short chains of amino acids long used across modern skincare. This formula brings that approach to scalp care.
The routine
Three steps, once a day
On clean or dry hair — whichever suits your day.
Part and target
Part your hair in a few places so the dropper can reach the scalp directly, not just the hair on top.
Apply a few drops
Squeeze the dropper along each parting, moving section by section so the serum lands on the skin.
Massage it in
Use your fingertips, not your nails, for about thirty seconds. Then leave it — nothing to rinse out.
What is inside
A peptide serum, kept deliberately simple
LINIGROW is built around peptides — short chains of amino acids that have become a staple of modern skincare — carried in a light base made for the scalp rather than the hair shaft.
The format matters as much as the formula. A 30 ml dropper lets you place the product exactly where you want it, which is the difference between treating your scalp and simply coating your hair.
- Peptide-based formula
- Light serum base rather than an oil
- 30 ml dropper bottle
- Leave-in — applied to the scalp, never rinsed out
Serum or oil
Why a serum, and not another hair oil
Both have a place in a routine. They are not doing the same job.

Frequently asked questions
What is LINIGROW Peptide Hair Growth Serum?
It is a 30 ml peptide serum made to be applied directly to the scalp. You part your hair, apply a few drops along each parting, massage it in and leave it — it is not rinsed out.
How do I use it?
Part your hair in several places, squeeze a few drops from the dropper along each parting, then massage into the scalp with your fingertips for about thirty seconds. Wash your hands afterwards.
How often should I use it?
Once a day. Morning or night both work — choose the one that fits your routine, because consistency matters more than the hour.
Will it leave my hair greasy?
It is a serum rather than an oil, with a light texture made to absorb into the scalp instead of sitting on the hair. Applied to the scalp rather than the lengths, it should not weigh hair down.
Do I rinse it out?
No. It is a leave-in serum. Apply it, massage it in and carry on with your day.
Can I use it with my other products?
Yes. Apply LINIGROW to the scalp first, then style as usual. Because it goes on the skin rather than the hair, it does not compete with the creams, oils or gels you use on your lengths.
Is it only for one hair type?
It is applied to the scalp, which is the same skin whatever your hair texture. Curly, coily, wavy or straight, the application is identical: part, apply, massage in.
What if it does not work for me?
Every bottle is covered by our 30-day guarantee. Contact us within 30 days of delivery and we will put it right.
