What is Sons?

Sons is a UK-based digital health company that specialises in men's hair loss. It was founded by Will Kennedy and Dr Adrian Gilbane after their own frustrations with expensive, impersonal hair loss clinics. The company focuses on making evidence-based treatments accessible through an online subscription model, with plans delivered discreetly to your door.

Sons is the only UK licence holder for both finasteride and minoxidil, the two active ingredients with the strongest clinical backing for treating male pattern baldness. Their medical products are licensed for sale in the UK and regulated by the Medicines and Healthcare products Regulatory Agency (MHRA). Prescriptions are issued through their partner pharmacy, The Independent Pharmacy.

The company holds B Corp certification, meaning it meets verified standards for social and environmental performance, accountability, and transparency.

How Sons hair loss treatment works

The process is straightforward. You complete a short online health consultation covering your hair loss history, general health, and goals. A UK clinician reviews your answers and, for prescription products, checks your NHS Summary Care Record. You're then recommended a personalised plan.

Products are delivered on a subscription basis. You choose your delivery frequency (monthly, every 3 months, every 6 months, or annually), and can cancel, pause, or adjust at any time. All deliveries arrive in discreet packaging.

Sons state that most men see reduced shedding within three to six months, with visible regrowth taking six to twelve months of consistent daily use. Results require ongoing treatment. Stopping means hair loss typically resumes.

Sons treatment plans

Sons offers several bundled plans, plus the option to buy individual products. Here's what's available:

Core Plan: Combines finasteride (oral tablet) and minoxidil (topical spray or oral capsule). These are the two clinically proven treatments for male pattern baldness. Sons claims a 94% effectiveness rate when used together, citing a published study from the National Library of Medicine. This is the most popular starting point.

Advanced Plan: Everything in the Core Plan plus the Sons Hair Growth Complex, a supplement containing nine ingredients including biotin, marine collagen, and Anagain.

Ultimate Plan: Everything in the Advanced Plan plus a DHT-blocking shampoo formulated with saw palmetto, argan oil, and vitamin B3. This is their most comprehensive offering.

Non-Prescription Plan: Built around minoxidil, DHT-blocking shampoo, and biotin. Designed for men in the early stages of thinning who prefer to avoid prescription medication.

All plans are also available in capsule-only versions for men who prefer not to use topical sprays.

Sons pricing

Pricing depends on which plan you choose and your delivery frequency. Longer commitments bring the monthly cost down. Here's a general guide (prices are correct at time of writing and may change):

Finasteride alone: From around £21/month on a 12-month plan, up to around £29/month on monthly delivery.

Minoxidil spray alone: From around £14/month.

Core Plan (finasteride + minoxidil): From around £29/month on a 12-month plan, up to around £40/month on monthly delivery.

Bundled plans offer better value than buying products individually. Delivery is free on orders over £40; orders under £40 carry a £2.99 fee. Sons ships via Royal Mail within 3 to 5 working days.

The science behind Sons

The core of every Sons plan is built on two active ingredients:

Finasteride is a prescription medication that blocks the conversion of testosterone into dihydrotestosterone (DHT). DHT is the hormone responsible for shrinking hair follicles in male pattern baldness, eventually cutting them off from nutrients and causing hair to fall out. Finasteride has been a licensed treatment for hair loss since 1997 and is the most recommended hair loss drug by hair transplant surgeons worldwide. Sons offers it as a 1mg daily tablet or as a topical spray.

Minoxidil is a non-prescription topical treatment (also available from Sons as an oral capsule) that works by increasing blood flow and oxygen to the scalp. This helps reactivate and revitalise shrunken hair follicles. Sons offers a 5% minoxidil solution, applied twice daily via their pump spray applicator. Sons is one of the only UK licence holders for manufacturing minoxidil.

Both treatments are supported by decades of clinical research. A 2015 randomised study published through the National Library of Medicine found that combining finasteride and minoxidil was effective in 94% of men with androgenetic alopecia.

The Sons Promise

Sons offers a money-back guarantee for new customers called the Sons Promise. If you follow your prescribed treatment plan for six months and don't see any improvement, they'll refund you. Full terms are available on the Sons website. This reduces the risk of committing to a longer plan, given that hair loss treatment requires patience and consistency to show results.

Sons customer feedback

Sons has over 3,000 reviews on Trustpilot with a rating of around 4.1. The majority of feedback is positive, with customers highlighting the ease of the subscription model, fast delivery, discreet packaging, and visible results after sustained use. The shampoo and conditioner range also receives consistently good feedback, even from men using it preventatively.

Common criticisms include occasional friction with the cancellation process and a lack of clarity around specific active ingredients on some product pages. It's worth reading the subscription terms carefully and noting your delivery dates so you can manage changes in good time.

How Sons compares

Sons operates in a growing UK market alongside Numan, Hims UK, and Manual. All four offer clinically proven treatments at broadly similar price points. The key differences:

Sons focuses purely on hair loss, which means a deeper product range and specialist expertise in that area. B Corp certified. Only UK licence holder for both finasteride and minoxidil.

Numan covers a wider range of men's health (including erectile dysfunction, blood testing, and weight management) but has fewer hair loss bundle options.

Hims UK offers hair loss alongside skincare and other conditions. Product range for hair is comparable to Sons, with free next-day shipping.

Manual has a broad product line across men's health. Their Complete Hair Loss Plan is competitively priced, but Sons generally offers more bundling flexibility.

For most men whose primary concern is hair loss, Sons is a strong choice thanks to its specialist focus, plan variety, and the 45% new customer discount.

Sons hair loss treatment: FAQs

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. Results vary by individual and stage of hair loss.

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 have concerns.

Is Sons available on the NHS?

Finasteride and minoxidil are both recognised treatments, but they're not routinely prescribed on the NHS for cosmetic hair loss. Sons offers a private online alternative with clinical oversight and home delivery.

Can you cancel Sons at any time?

Yes. Sons says subscriptions are flexible and can be cancelled at any time. Some customers have reported friction with the process, so it's worth keeping track of your subscription dates and checking the terms.

Is Sons only for men?

Currently, yes. Sons' treatments are designed for male pattern baldness (androgenetic alopecia). The prescription products are only suitable for men aged 18 to 65 (or 75 for some plans).

Can Sons regrow hair that's already gone?

Sons works best at slowing loss and thickening hair where follicles are still active. If follicles have been dormant for a long time, regrowth is less likely. The earlier you start, the better the results tend to be.
