The Prevention Scalp Serum
82 reviews
Here’s your first response: stop hair thinning before it begins! As your frontline of defense, The Prevention Scalp Serum for hair growth nourishes your follicles, stopping them from shrinking to maintain thick, full-looking hair. By working like a stress repellent for your scalp, it blocks DHT—the hormone that triggers hair thinning—while reducing environmental and aging-related damage. Think of this step like sunscreen for the scalp.
This solution in our serum for scalp health includes a mix of patented ingredients (Procapil®, Capixyl®, Anagain® and RootBioTec®), all representing today’s most advanced plant-based solutions for scalp health, alongside our proprietary blend of liposomal encapsulated L ascorbic acid. When combined with our treatment serum, these active ingredients proved to outperform minoxidil—without the side effects—in a peer-reviewed randomized controlled trial.
Just apply a few drops of our hair thinning prevention serum to your scalp and massage in the product. Repeat this process every night.

Unique Scalp Soothing Blend - Piroctone, bisabolol, panthenol and zinc combine to soothe the scalp and reduce harmful 'inflammageing'.
Procapil® - A blend of peptides and extracts from
olive tree leaves that work to block the ageing hormone DHT.
Capixyl® - A blend of peptides and red clover
extract to help strengthen follicles.
Anagain® - A pea sprout extract that restarts
dormant growth cycles, while extending the anagen phase.

stimulates the scalp to activate sluggish follicles.

Emily G. This product is great at preventing hair thinning!

Varenya N. I bought the prevention serum after seeing it advertised on instagram! I’ve always believed that scalp health really is fundamental for healthy hair, so I wanted try this product when I saw the ads. I’ve had dandruff, and my scalp tends to become itchy and flaky, especially with certain shampoos and conditioners. Since I started using this serum, I’ve noticed a really significant improvement in my scalp - it feels more comfortable, less flaky and less itchy! For that alone I would highly recommend this product!!

Erik S. I purchased this along with the treatment serum and have been using both twice daily. It’s been helping me not lose as much hair. Totally recommend this product especially if you want an alternative to minoxidil.

Vivian H. Not greasy and easy to apply

kianayek This the second time I am repurchasing this product because I am genuinely impressed! I’ve noticed significant changes in my hair after a few months. The serum has a light texture and absorbs quickly. I love how it doesn’t make my hair greasy at all! I have been applying it consistently as directed with the Treatment serum that they sell and the results have been encouraging. I highly recommend this product for anyone looking to boost their hair growth!

John I have been using both the Prevention Serum and the Treatment Serum. After 6 months of using the KilgourMD system, my hairline is visually back to where it was three years ago. I can only say I wish I had been using it sooner!
One trick I learned by experimenting is that, it works better if I apply 2-3 times a day instead of just once a day.

Sho Item was exactly as described and arrived promptly. I've just started using it, but the scent is good. Excited to keep using it!

Tanya I initially came across this serum after reading more about the importance of scalp health in relation to healthy hair growth. This product was listed in an article on Who What Wear so I decided to try it since it was designed by a dermatologist. So far I have found that this serum is super gentle on the scalp and is non-greasy which is important for me. It also doesn't cause any scalp itch or irritation and doesn't cause build up even though I don't wash my hair every day.
I've been using it for about 3 months and found new baby hairs along the hair line (particularly around the temples and front of the hair line). I also noticed that have less dandruff now! I also highlight and tone my hair and haven't noticed any issues.
Overall very happy with this!

Alex I’ve been using this hair growth product set (the prevention scalp serum and the treatment scalp serum) for a few months now, and I’m genuinely impressed with the results! What stood out to me the most is the scientific approach behind it—it’s clear that a lot of thought and research went into formulating this. My hair feels thicker, healthier, and I’ve noticed significant growth in areas that were thinning. It’s refreshing to finally find a product that actually works as promised. I highly recommend this to anyone looking for an effective solution for hair growth!

Ann-Marie H. I ordered the Kilgour MD prevention serum along with their treatment serum, and I absolutely LOVE them!! I was looking for hair products that have scientific backing behind them, and the Kilgour MD products bring just that. Having a dermatology-trained physician formulating these serums makes all the difference. They are easy to apply, smell nice, and are non-greasy. I use them together as recommended, and they have already made my hair feel healthier. Highly recommend these if you’re looking for a healthy scalp and stimulation of hair growth!!
