Cool Factor: 4/5

What is Sons?

Sons is a UK-based digital health company that specialises in men's hair loss. Founded by Will Kennedy and Dr Adrian Gilbane after their own frustrations with overpriced, confusing hair loss clinics, Sons focuses on making clinically proven treatments accessible, affordable, and stigma-free.

The company is a certified B Corp and claims over 400,000 customers to date. Their products are regulated by the Medicines and Healthcare products Regulatory Agency (MHRA), and prescriptions are handled through their partner pharmacy, The Independent Pharmacy. Sons is the only UK licence holder for both finasteride and minoxidil, the two treatments with the strongest clinical evidence behind them for male pattern baldness.

For a full breakdown of what Sons offers and how to get started, see our Sons hair loss treatment detail page.

First impressions

Signing up to Sons is refreshingly simple. You complete a short online consultation covering your hair loss history, general health, and what you're hoping to achieve. A UK clinician reviews your answers (and your NHS Summary Care Record for prescription products), then recommends a personalised plan. The whole process takes a few minutes.

Packaging is discreet and well-designed. Sons clearly care about the unboxing experience, and the branding has a clean, modern feel that doesn't scream "hair loss treatment" from the outside. It's a small detail, but it matters when you're dealing with something that can feel a bit personal.

The treatments in detail

At its core, Sons offers two clinically proven active ingredients: finasteride (a DHT blocker taken as a daily tablet or topical spray) and minoxidil (a topical spray or oral capsule that stimulates blood flow to the scalp). These aren't new or experimental. Finasteride has been a licensed hair loss treatment since 1997, and minoxidil has decades of clinical evidence behind it.

Sons bundles these into tiered plans:

The Core Plan combines finasteride and minoxidil, the two heavy hitters. The Advanced Plan adds their nine-ingredient Hair Growth Complex. The Ultimate Plan goes further with DHT-blocking shampoo on top. And if you're not ready for prescription treatments, there's a Non-Prescription Plan built around minoxidil, shampoo, and biotin.

Sons claims a 94% effectiveness rate for halting hair loss when finasteride and minoxidil are used together, citing published research from the National Library of Medicine. That's a strong claim, but it's backed by peer-reviewed studies. In practice, most men can expect to see reduced shedding within three to six months, with visible regrowth taking six to twelve months of consistent use.

One criticism worth noting: some independent reviewers, including the Wimpole Clinic, have pointed out that Sons' website doesn't always clearly name the specific active ingredients in every product listing. For a company that positions itself on transparency, this feels like an area that could be tightened up.

Pricing and value for money

Sons' pricing depends on which plan you choose and how often you want it delivered. Longer commitments bring the monthly cost down significantly.

For the Core Plan (finasteride and minoxidil combined), you're looking at around £40 per month on monthly delivery, dropping to roughly £29 per month if you commit to a 12-month cycle. Finasteride alone starts from around £21 per month on an annual plan. Minoxidil spray starts from around £14 per month.

Compared to buying finasteride and minoxidil separately through a high-street pharmacy or GP prescription, Sons is competitive, particularly on the bundled plans. Numan and Hims UK offer similar products at roughly comparable price points, but Sons tends to have more bundle options and a broader product range focused purely on hair loss.

Sons also runs regular discount offers. If you're looking for one, check our Sons discount code page for the latest deals.

There's also the Sons Promise: a money-back guarantee for new customers who follow their prescribed treatment for six months without seeing improvement. That's a genuinely confidence-building offer, and not something every competitor matches.

What customers are saying

Sons has over 3,000 reviews on Trustpilot. The majority of feedback is positive, with customers praising the ease of the subscription model, fast delivery, and visible results after sustained use. The shampoo and conditioner, in particular, seem to get consistently good feedback even from men using them preventatively.

On the negative side, there are a handful of complaints about cancellation issues and subscription management. Some users have reported difficulty pausing or cancelling their plan. It's worth reading the subscription terms carefully before committing, and keeping a note of when your next delivery is due.

The verdict

Sons does what it sets out to do: it makes clinically proven hair loss treatment accessible, affordable, and easy to stick with. The science behind finasteride and minoxidil is well established, and Sons' subscription model removes the friction of having to remember to reorder or visit a clinic. The B Corp certification, the money-back guarantee, and the MHRA-regulated supply chain all add credibility.

Where it falls slightly short is in on-site transparency around active ingredients and some friction points in subscription management. These aren't dealbreakers, but they're worth being aware of.

4 out of 5

Overall, a solid 4/5 Stone cold. Sons earned its score through a genuinely well-designed service built on proven science, fair pricing, and a growing track record with over 400,000 UK customers. It didn't quite hit Ice cold because the ingredient transparency on the website could be better, and the cancellation process has caught a few users out. If you're in the early-to-mid stages of male pattern baldness and you want a no-fuss, evidence-based approach, Sons is well worth a look.

Sons hair loss review: FAQs

Is Sons hair loss treatment worth it?

In our opinion, yes, particularly if you're in the early stages of male pattern baldness and want a convenient, subscription-based approach. The treatments are clinically proven, competitively priced, and the money-back guarantee after six months reduces the risk. See our Sons detail page for a full breakdown of plans and pricing.

How long does Sons take to work?

Most men notice reduced shedding within three to six months. Visible regrowth typically takes six to twelve months of consistent daily use. Sons is not a quick fix, and stopping treatment usually means hair loss resumes.

Does Sons have side effects?

Finasteride can cause side effects in a small number of men, including reduced libido and mood changes. Minoxidil may cause temporary scalp irritation. Sons' clinical team reviews your suitability before prescribing, and you can contact their aftercare team if you experience any issues.

Can you cancel Sons at any time?

Sons says subscriptions are flexible and can be cancelled at any time. However, some Trustpilot reviewers have reported friction with the cancellation process, so it's worth keeping track of your subscription dates and reading the terms carefully.

How does Sons compare to Numan and Hims UK?

All three offer clinically proven treatments at similar price points. Sons stands out for its pure focus on hair loss, broader range of bundled plans, and B Corp certification. Numan and Hims UK offer treatments for a wider range of men's health conditions beyond hair loss. For most men whose main concern is hair thinning, Sons is a strong choice.

Is Sons regulated in the UK?

Yes. Sons' medical products are licensed for sale in the UK and regulated by the MHRA. Prescriptions are issued through their partner, The Independent Pharmacy.
