Best hair-growth serums for men: Nutrafol, Nioxin, The Ordinary and more

A crash course on hair serums and why they matter

My partner and I have two very different approaches to combating hair loss. I’m all-in on the pills, potions and procedures: that’s finasteride, minoxidil and even a hair transplant – and I’m more than content with the full, natural-looking results. He, on the other hand, prefers the “less clinical” route and relies heavily on hair growth and hair fortifying serums as well as a healthy lifestyle and an anti-hair loss shower and styling regimen. It’s those hair serums we’ll address today, which work a lot like facial serums in that they deliver nourishing ingredients to the scalp and follicle to promote stronger, thicker hair growth.

Before I go on, I should note three things:

1. I am not a dermatologist. Only your dermatologist can prescribe the best method for you, while also supervising the process should you opt for a clinical route. So, see your doctor and trust them.

2. The most effective, lasting results will always be from the prescriptive or procedural methods (including the over-the-counter minoxidil drops or spray). These options, particularly finasteride, come with infrequent (but notable) risks, namely sexual side effects and should thus be monitored closely.

3. You should set realistic expectations with your hair. Do the requisite research and, of course, involve your doctor. However, know that receding hair can be slowed but not restored. Thinning hair can only be restored and maintained if it was lost in the last few years. And you’ll have to continue whatever regimen you set out on for the rest of your life if you want to continue to see results.

Now, back to serums.

What are hair growth serums?

Hair growth serums act like little liquid vitamins for your hair and scalp. Think of them as daily boosters (packed with things like Vitamin B, peptides and tea tree oil) to promote a healthy scalp, strong bulbs and an optimal growth environment. They focus on any or all of the following: circulation and nutrient delivery to the follicles; mitigating dihydrotestosterone (DHT, for short, is the androgen that actively thins and suffocates the follicles); defense against toxins and pollution (they’re packed with antioxidants); and scalp harmony (to prevent flaking, irritation and the like).

The effects of hair serums, like prescriptive options, may take months to fully notice, particularly in terms of overall fullness and density. They can and often do wake up dormant, wilting follicles, but not to the extent of minoxidil or finasteride.

Hair serums will be most successful if paired with other pro-hair-health choices, like a good diet, regular exercise, ample sleep, minimal alcohol and drug use and stress minimising techniques. And lastly, while you should absolutely see a doctor and discuss all of your options, these serums are generally safe to use without such monitoring or consulting. They often make a terrific additional supplement for people using minoxidil and finasteride, too. (Minoxidil by day, serum by night, for example.) Think of it this way: The serums can only help – it’s just a matter of how much help you need, and how you choose to deploy it. Should you want to be like my partner and slow gradual hair thinning (while probably having to ultimately accept it in the next 10 to 15 years), or if you want to add a daily liquid vitamin to your line of defense, then please consider these excellent hair serums, which do exactly that.

Lastly, note that hair growth serums are different from hair repair serums, which work more like a mask and are applied throughout the strands themselves. These repair serums resuscitate damaged or dry hair. In this article, we’re talking about hair serums that you drop onto the scalp itself, to impact growth and renewed vitality at the root of thinning, endangered hair.
