After the stress of the past few years, your hair may not be living its best life right now. And spending more time staring at your own face on video calls means you're more likely to notice if it’s not looking as, ahem, lustrous as you’d like.

Or maybe there are a few more strands than usual clogging up the shower drain? Good news: there’s a shampoo for that.

Okay, we can’t promise voluminous curls like Timothee Chalamet or enough hair to pad out a Thor-worthy man-bun, but there are a few products that can minimise breakage and promote growth, leaving you with not only more hair, but healthier lengths too.

We tested the best hair growth shampoos for men (and their corresponding conditioners, if they have them). Here's a glance at our winners, but scroll on for more information on the testing process.

    Can Shampoos Really Regrow Hair?

    We’ll cut to the chase. No shampoo will be able to give you the same volume you had in your teens, but they can help create a healthy environment to encourage strands to grow as strong as possible.

    If you have genetic hair loss, then you need something more heavy-duty than a thickening shampoo. Male pattern baldness is a one-way street and without a hair transplant, the best you can do is hold onto what you've still got. The likes of minoxidil and finasteride have been shown to help there, but they do mess with your testosterone levels and can cause dryness and irritation. The shampoos we've tested here are for more everyday – and reversible – hair loss issues.

    How We Test Hair Growth Shampoos

    Our panel of 700 testers – all self-diagnosed with mild to extreme hair loss or thinning – tried a range of shampoos for between one and two months. The products aimed to correct at least one of the three main causes of hair loss: breakage, thinning and root or scalp issues.

    Testers noted any differences to their hair’s condition and appearance and fed back on how their scalp felt throughout the trial period.

    In the lab, our experts tested anti-breakage shampoos by combing through hair switches that had been treated with each product and comparing them to untreated switches. The easier the treated switches were to comb, the lower the risk of breakages and fallout.

    For products that claim to thicken and stimulate roots, our lab team used a HairMetrix machine to analyse exactly how much impact each shampoo had on hair thickness and density. For all the shampoos on our list, we’ve stated whether they contain parabens, sulphates and silicones, in case any of those are a dealbreaker.

    Note: These products are not designed to treat those with medical or hereditary conditions such as alopecia or male pattern baldness. Please seek a medical professional for advice.

        The majority of our testers said this shampoo provided an instant volumising effect to ends, making hair look thicker and fuller.

        Our panel found this was especially gentle on those with sensitive scalps and left a shinier head of hair as a result. An added bonus is the fragrance, a blend of vetiver and amber.

        Kevin Murphy Stimulate Me Wash

        Dirty innuendos aside, the ‘Stimulate Me’ shampoo from celebrity hairdresser Kevin Murphy’s range came out on top for hydrating parched hair, while simultaneously stimulating growth.

        Our testers noticed less shedding, and all agreed that their hair loss issues had improved by the end of the trial. It proved effective at boosting thickness in the lab, too.

        This shampoo left hair shiny and silky, making it easier to style after washing. It also provided a pleasant tingling sensation to the scalp, which testers said they enjoyed.

        While testers didn’t spot any significant hair growth, there was a noticeable difference in how full the hair looked, as well as reduced hair breakage.

        Philip Kingsley Density Thickening Shampoo

        Dandruff is a common problem, but it can be embarrassing, so let's nip it in the bud. This shampoo contains BHAs (aka beta hydroxy acids, aka an acne-busting skincare staple) to exfoliate dead skin gently.

        The idea of putting acids on your scalp may sound alarming, but no testers reported any irritation, and everyone found it effective at sending dry flakes packing. It helped to reduce shedding and left hair looking thicker.

        It’s common sense, really: if your hair is stronger, it’s less likely to fall out and leave you with baldy bits.

        This shampoo gave thirsty strands some much needed H2O, taming flyaways and reducing fallout. This all helped make hair more manageable for combing and styling, with many testers seeing fewer breakages and more volume at the roots.
