Losing more hair? Our hair serum can help
More than 60% of men notice their hair thinning before the age of 35. Whether it's stress, genetics or lifestyle, hair loss can knock your confidence and creep into everyday life.
This spray serum lets you act early: it helps reduce hair loss from the root and gives your hair a thicker, fuller look – with an application that couldn't be easier.
Powerful actives that help reduce hair loss and support growth
This serum combines five cutting-edge actives to target hair loss at the source:
Capilia Longa™ PPF: a biotech turmeric extract shown to reduce hair loss by up to 89% in 56 days, supporting growth from the root.
Anargy™ (oligopeptide-1 + glycoproteins): strengthens the follicle, improves hair density and helps repair weakened hair.
Epitensive™: with oligopeptide-2, revitalises the scalp and helps extend the hair's growth phase.
Hyaluronic acid: hydrates deeply and helps the actives absorb.
Hydrolite®: boosts the treatment's effectiveness and helps the ingredients penetrate.
A light, non-greasy, residue-free formula that works intensively to help restore hair density.
Invisible texture, fast absorption, real results
Unlike many hair loss tonics and lotions, our serum has a light, non-greasy texture. It sprays on without leaving hair sticky or looking unwashed, absorbs in seconds and lets you get on with your day without feeling a thing. You may notice the first changes within days. An effective hair thickening treatment, discreet and designed around your life.
Made in Europe to the highest quality standards.
Never tested on animals, in line with our cruelty-free philosophy.
Formulated without parabens, silicones, colourants or aluminium.
Packed in sustainable, minimalist packaging.
WHAT OUR CUSTOMERS SAY
Frequently asked questions
When will I start to notice less hair loss?
With daily use, the first results are visible within a few weeks. Capilia Longa™, the serum's key active, has studies showing 89% less hair loss in 56 days and +52% hair density after 150 days.
How do I apply the hair serum? On wet or dry hair?
Wash your hair with the hair thickening shampoo, towel-dry it and spray the serum directly onto the scalp, with your hair dry or slightly damp. Focus on the thinner areas. No rinsing. No residue. Your hairstyle stays put.
Does the serum work on a receding hairline?
Yes. It works on the hair follicle whatever the area, and does especially well on the hairline and thinner areas, which is exactly where follicles start to weaken first. Density is easier to rebuild early on, so waiting won't help.
Can I use it with any shampoo, or only FETĒN's?
It works with any anti-hair loss shampoo. Pairing it with FETĒN's Hair Thickening Shampoo boosts results because the actives complement each other, but if you already use another one, you can carry on with it.
Can I use it every day?
Yes. It's formulated for daily use with the latest biotech actives, and contains no parabens or silicones. Made in Europe, sustainable and cruelty-free.
What are the key ingredients?
Formulated with Capilia Longa™, a natural-origin active clinically tested against hair loss.
