the Science

Unfortunately there is currently no one-off “fix” for Male Pattern Baldness. However, there are now treatments including our Treatment Sprays and Daily Capsule available that are effective in regrowing hair and slowing down the hair loss process.

Many Unthin products contain a class of medication called 5-alpha reductase inhibitors, known for their use in blocking Dihydrotestosterone (DHT). If you are looking for products suitable for women, please visit www.volyoume.co.uk

Yes. We are a pharmacy registered with the GPhC. The short questionnaire consultation will ensure your suitability for our Treatment Spray; checking any allergies and other factors which may mean the treatment is not suitable for you. Unthin subscribers also have access to a dedicated Pharmacist who will answer any queries or concerns at any point during the treatment schedule.

Unlike other treatments available, Unthin is dedicated to helping men overcome the effects of androgenic alopecia. Each product is easy to use and is the best quality available on the market. We have a specialist team available to support patients on their journey - you can contact them at any time to ask questions about your treatment, how to use the product, and what results to expect.

Unthin treatments are only available via this website; this means that our clinical team are able to check your suitability for the treatment and provide appropriate after care. Most male pattern baldness treatments are only available through private prescription.

An unlicensed medicine can be defined in several ways: - A medicine that is formulated in an alternative version to the licensed medicine (e.g., a oral medication made into a topical liquid formulation, or a medication made in a different strength to the original licensed version). - A medicine that has no licence at all. - A medicine that has a licence in other countries, but not the UK. All our unique formulations combine ingredients that are manufactured by fully regulated MHRA manufacturing site.

The hair growth cycle

Phase 1: anagen

Hair grows in cycles, starting with the anagen phase, where strands actively grow from the follicle. This phase lasts 3 to 5 years and determines how long your hair can get. The longer the anagen phase, the more potential for thicker, fuller hair.

Phase 2: catagen

Next is the catagen phase, a brief 2–3 week transition where growth stops and the follicle begins to shrink. Only a small percentage of hairs are in this phase at any given time, but it's a key part of the natural cycle.

Phase 3: telogen

Finally, hair enters the telogen phase, the resting stage that lasts around 3–4 months. During this time, old hairs are shed and new ones prepare to grow. Daily shedding (around 50–100 hairs) is normal, but when more follicles enter this phase too early—often due to DHT or stress—hair loss becomes noticeable. Treatments like Unthin help counter this by supporting the growth phase and reactivating dormant follicles.

the Products

Yes, the Treatment Spray is suitable for restoring hairlines. We recommend applying it to the most affected areas and then massaging across the whole scalp. You will benefit from hair growth in the areas required, and overall thicker hair throughout.

While hair transplants may appear like the be all and end all solution, unfortunately they are not as permanent as they sound. They require regular maintenance, often with the aid of solutions such as ours.

When using our products as instructed, you can expect to see initial results after 3 months and then after 6 months the hair growth should be very noticeable. You will need patience and faith that the product will produce results.

Our Treatment Spray is applied through 6 sprays, twice daily. This provides the scalp the correct amount of solution designed for optimal hair regrowth: the liquid can then be massaged into the scalp.

The Treatment Spray is odourless and non-greasy, meaning it won’t affect your look.

The ingredients

Minoxidil
  • Reactivates Dormant Hair Follicles: Minoxidil extends the growth phase (anagen) of the hair cycle, helping dormant follicles start producing new strands.
  • Improves Blood Flow to the Scalp: It widens blood vessels, increasing oxygen and nutrient delivery to hair follicles—crucial for healthy, sustained growth.
  • Clinically Proven to Regrow Hair: Backed by decades of research, Minoxidil is FDA-approved and shown to improve density and scalp coverage over time.
Finasteride
  • Blocks DHT, the Root Cause of Hair Loss: Finasteride reduces levels of dihydrotestosterone (DHT)—the hormone responsible for shrinking hair follicles and causing male pattern baldness.
  • Prevents Further Thinning: By lowering DHT, Finasteride helps preserve existing hair and prevent continued loss at the crown and hairline.
  • Clinically Proven for Long-Term Results: Daily use has been shown to slow, stop, and even reverse hair loss in many men—especially when combined with topical treatments.
Dutasteride
  • Blocks DHT More Effectively: Dutasteride inhibits both Type I and Type II 5-alpha reductase enzymes, significantly reducing DHT—the hormone responsible for shrinking hair follicles.
  • Slows or Stops Hair Loss: By lowering DHT levels, Dutasteride helps prevent further thinning, especially at the crown and mid-scalp.
  • May Promote Regrowth: Some users experience visible hair regrowth over time, particularly when combined with topical treatments like Minoxidil.
Azelaic Acid
  • Blocks DHT at the Follicle Level: Azelaic Acid has been shown to inhibit 5-alpha-reductase, the enzyme that converts testosterone to DHT—a key hormone linked to hair loss.
  • Reduces Scalp Inflammation: It helps calm irritated skin and reduce redness, creating a healthier scalp environment for hair growth.
  • Supports Stronger, Healthier Hair Regrowth: By improving follicle health and minimizing the effects of DHT, Azelaic Acid can support the regrowth of thicker, more resilient hair.
Tretinoin
  • Boosts Absorption of Minoxidil: Tretinoin helps increase skin cell turnover, allowing active ingredients like Minoxidil to penetrate deeper and work more effectively.
  • Stimulates Hair Follicle Activity: By promoting cell regeneration and increasing blood flow to the scalp, Tretinoin can help activate dormant follicles and support new hair growth.
  • Reduces Scalp Buildup: It helps remove dead skin cells and excess sebum, creating a healthier scalp environment for hair to grow.


Biotin
  • Supports Keratin Production: Biotin helps the body produce keratin, the key structural protein that makes up your hair, promoting stronger, thicker strands.
  • Strengthens Hair from Within: As a B-vitamin (B7), Biotin plays a vital role in cell metabolism and helps nourish hair follicles at the root.
  • Helps Reduce Breakage and Shedding: With consistent intake, Biotin can improve hair elasticity and resilience, leading to less breakage and fuller-looking hair over time.
