- 9 min reading time
Hair loss, thinning hair, or just... patience running out? A hair growth serum can really be the solution. Hair growth serums work – provided you use the right products and apply them correctly. At Haarspullen.nl, we see this every day. Based on years of experience and honest customer reviews, we now have a solid list of hair growth serums that actually show results.
In this blog, we’ll guide you through what really works, what to watch out for, and how to get the most out of a hair growth serum.
Top 5 hair growth serums that really work at a glance
Before we dive deeper into how hair growth serums work, we’ve selected the top 5 hair growth serums that really work for you:
Living Proof Scalp Care Density Serum: We often recommend this hair growth serum if your hair is thinning but you don’t want a heavy or greasy feeling. The serum is super light, absorbs quickly, and quietly does its work on your scalp. After a few weeks, your hair feels fuller and looks denser, especially at the roots. Great if you want subtle extra volume and hair density without changing your entire routine.
Redken Acidic Grow Full Serum: This is one of those serums that makes you think: okay, this feels good right away. It nourishes your scalp, strengthens your hair, and helps reduce hair breakage, which is important if you want your hair to grow. Thanks to the low pH, your hair stays healthier, making it look fuller in the end. Ideal if you notice your hair breaks easily or seems to stop growing.
The Ordinary Multi-Peptide Serum For Hair Density: This one is perfect if you like a no-nonsense approach. No fuss, just a serum that really focuses on hair density. It feels light, doesn’t stick, and is easy to use. Many people notice after a while that their hair looks fuller and feels stronger. Great if you want to address thinning hair without immediately using a whole product line.
Nioxin Hair Booster Serum: This serum is ideal if you have specific spots where your hair is thinning, such as at your hairline or crown. You apply it very precisely, allowing you to work locally on stronger and fuller hair. It stimulates the scalp and supports hair growth exactly where you need it. Highly recommended if you want to tackle hair loss in a targeted way.
Mediceuticals Numinox Hair Follicle Revitalizer Serum: This is a nice option if you feel your scalp could use a little extra. It stimulates the scalp and helps your hair follicles become more active, which ultimately results in stronger and fuller hair. The serum absorbs quickly and feels fresh, without making your hair greasy. Suitable for both men and women who notice their hair thinning.
Do hair growth serums even work?
Short answer: yes, but only if you use them the right way.
And no, it’s not magic in a bottle (if only it were).
Hair growth works in phases and that process takes months. That means you won’t suddenly see a full head of hair after two weeks, no matter how good a serum is. Hair growth serums support and stimulate what is already there: they help your hair grow stronger, reduce hair loss, and create the right foundation on your scalp. They don’t make new hair ‘appear’ where no hair follicles are active anymore.
Whether a hair growth serum works for you depends on a few important factors:
-
The cause of your hair loss. Stress, hormonal changes, hereditary factors, or hair breakage all require a different approach.
-
Consistent use. Occasional application won’t save you. Use daily or as advised.
-
The ingredients. Not every serum is the same. Active ingredients really make the difference.
So see a hair growth serum as a long-term investment in your hair. Give it time, use it consistently, and choose a serum that especially fits your situation!
Can thinning hair become much thicker?
Honest answer: yes, to a certain extent.
If your hair is thinning because hair follicles are temporarily less active, for example due to stress, hormonal fluctuations, or hair breakage, your hair can definitely become fuller and stronger again. By properly caring for your scalp and using the right products like a hair growth serum, your hair follicles essentially get a signal to become more active again. The result? Hair that feels thicker and looks visibly fuller.
But: if hair follicles are permanently inactive (for example, in hereditary hair loss), hair growth serums cannot grow new hair where there is none. What they do do is make the most of the hair you still have: stronger, healthier, and less brittle.
What is the best hair growth serum for men
Mediceuticals Numinox Hair Follicle Revitalizer Serum is a great choice for men who notice their hair thinning. The serum focuses on activating the hair follicles and improving the condition of the scalp. It absorbs quickly, feels fresh, and helps hair look stronger and fuller, especially in early hair loss.
Important to know: Hair loss in men often starts around their twenties or thirties and is usually hereditary. The hair follicles become more sensitive to hormones, causing the hair to thin. A hair growth serum cannot stop this process and won’t grow new hair where follicles are no longer active. What a serum like Mediceuticals Numinox does do is support the scalp and get the most out of the hair that’s still there, especially if you start early.
Ingredients proven to have an effect on hair growth
Not every hair growth serum works the same. It depends on the ingredients. There are a number of key ingredients that we know from experience and research can support hair growth — provided you use them consistently, of course!
Peptides are one example. They support the hair follicles and help hair grow stronger. Many serums aimed at hair density and less hair loss therefore contain a peptide complex.
Caffeine stimulates the scalp and can help keep hair follicles more active. It basically gives your hair roots a little wake-up call, helping hair stay in the growth phase longer.
Niacinamide (vitamin B3) support scalp circulation and help keep the skin barrier healthy. A calm, well-circulated scalp is essential if you want to stimulate hair growth.
Biotin and other B vitamins play a role in building keratin, the main building block of your hair. They don’t suddenly make your hair thicker, but they do support stronger and healthier hair growth.
Plant extracts, such as rosemary or ginseng, are often added to stimulate and balance the scalp. They mainly work supportively but are a nice addition to a good hair growth formula.
When will you see results from a hair growth serum?
Patience is key when it comes to hair growth serums. It’s important to understand that hair growth is a slow process. The process of a hair growth serum looks roughly like this:
-
After 4–6 weeks: less hair loss
-
After 8–12 weeks: baby hairs / more volume at the roots
-
After 3–6 months: visibly fuller hair
How to use a hair growth serum
Using a hair serum doesn’t have to be complicated. In fact: simple and consistent works best.
-
Always apply the serum to a clean scalp. This can be on towel-dried hair after washing, or on dry hair if the serum is suitable for that. Distribute the product with the pipette or spray directly onto the scalp – especially at the roots or on spots where your hair is thinning. You really don’t need to wet your entire hair; it’s about the skin underneath.
-
Then gently massage the serum in with your fingertips. Don’t rub hard, just work it in calmly. This not only helps with product absorption but also immediately stimulates blood flow in your scalp.
-
And perhaps most importantly: keep using it. Hair growth serums don’t work overnight. Use the serum daily or as advised and give it at least a few months. Skipping or stopping because you ‘don’t see anything yet’ is exactly where it often goes wrong.
Think of a hair serum as a fixed moment in your routine, just like your skincare. The more consistent you are, the greater the chance of visible results!
How often should I use a hair growth serum?
Usually daily or at least 3–5 times a week. This varies per product. Consistency is more important than quantity.
What if I stop using the hair growth serum?
If you stop using your hair growth serum, your hair usually returns to its natural growth rate. The results achieved sometimes remain, but maintenance is not guaranteed.
What else affects hair growth?
Hair growth is a process that doesn’t only depend on the products you use, like hair growth serums. There are various factors that influence how fast and healthy your hair grows. Nutrition plays a big role, for example. Getting the right vitamins and minerals, such as biotin, vitamin D, and zinc, can help make your hair stronger and healthier.
Besides that, stress and sleep have a big impact on your hair growth. Chronic stress can worsen hair loss, while a good night’s sleep is essential for cell repair – including your hair follicles! And don’t forget scalp health. A healthy scalp is the foundation for hair growth. Regular massages and avoiding irritating ingredients in your care products can help stimulate blood circulation and keep your hair follicles in top shape.
And finally: Unsure which hair growth serum suits your situation best? At Haarspullen.nl, we’re happy to help you further. Sometimes a small step in your routine is enough to make your hair feel stronger, healthier, and fuller again.
