01
Minoxidil: The Active Ingredient
Minoxidil is the active pharmaceutical ingredient responsible for encouraging hair regrowth in both Regaine and Superdrug's branded products. It's classified as a pharmacy (P) medicine in the UK, meaning you can purchase it over the counter from a GPhC-registered pharmacy without a prescription. It is not typically prescribed on the NHS for hair loss, so most people buy it privately.
The most common strengths available are 2% and 5%. The 5% strength is generally considered more effective for men, while women are often advised to start with 2%, or use 5% foam as per the product leaflet, due to potential side effects like facial hair growth. Always refer to the product information leaflet (PIL or 'emc leaflet') for precise dosage instructions and warnings.
02
Foam vs. Solution: What's the Difference?
Both Regaine and Superdrug minoxidil are available in two primary formats: a topical solution and a topical foam. The solution is typically applied with a dropper, while the foam is dispensed directly onto the scalp. The choice between formats often comes down to personal preference, convenience, and how the product feels on your hair and scalp.
Some users find the foam easier to apply and less greasy, particularly if they have longer hair. The solution might be preferred by others for its precise application to specific areas. It’s worth noting that the US equivalent of Regaine is called Rogaine. Other brands, like Kirkland, are US brands whose availability in the UK can vary, often through importers or Costco.
03
Considering Inactive Ingredients
While minoxidil is the active ingredient, the 'inactive' ingredients in a product can significantly impact your experience. Common inactive ingredients include propylene glycol and alcohol. Propylene glycol, often found in the solution format, can cause irritation, itching, dryness, or allergic reactions for some individuals. Alcohol is used to help the minoxidil dissolve and evaporate quickly, but it can also be drying to the scalp.
If you experience scalp irritation or sensitivity with a minoxidil solution, it might be beneficial to try a foam formulation, which often contains less or no propylene glycol. Always check the specific ingredients list on the product packaging or leaflet. Should you experience any concerning side effects, report them to the MHRA via the Yellow Card scheme, or contact NHS 111 for advice.

Availability and Cost Comparison
Regaine is a widely recognised brand available from most large pharmacies, supermarkets with a pharmacy section, and online retailers across the UK. Superdrug's own-brand minoxidil is, as expected, primarily available in Superdrug stores nationwide and through their online platform. Other UK online men's health services like Numan and Manual also offer minoxidil treatments.
When comparing costs, it's most accurate to compare the cost per month, as pack sizes can vary. Both brands offer competitive pricing, and Superdrug's own brand is often positioned as a more budget-friendly alternative to Regaine. Look out for multi-pack discounts or subscription options, which can further reduce the monthly cost. For another option, FOLIGAIN is also available from foligain.co.uk.
05
Who Might Each Option Suit?
Regaine, being a well-established brand, might appeal to those who prefer a product with a long track record and extensive marketing. It's often available in convenient multi-packs and a range of strengths and formats, making it accessible for many. Both men and women will find appropriate formulations within the Regaine range.
Superdrug's own-brand minoxidil is a strong contender for those seeking a more affordable option without compromising on the active ingredient. It's an excellent choice for budget-conscious individuals who still want the proven effectiveness of minoxidil. Ultimately, the best choice depends on your budget, preference for format (foam or solution), and any sensitivities you might have to inactive ingredients.

Frequently asked questions
Is minoxidil available on the NHS in the UK?+
No, minoxidil for hair loss is not typically prescribed on the NHS. It is a pharmacy (P) medicine that can be purchased over the counter from GPhC-registered pharmacies or online without a prescription.
What is the difference between Regaine and Superdrug minoxidil?+
The main difference lies in branding and inactive ingredients. Both contain the same active ingredient, minoxidil, in the same strengths (2% and 5%). Superdrug's own brand is generally a more cost-effective option, while Regaine is a well-established brand. Always check inactive ingredients if you have sensitivities.
Can women use 5% minoxidil?+
Women are often advised to start with 2% minoxidil. However, 5% minoxidil foam is often indicated for women, as per product leaflets. Always refer to the specific product information leaflet for dosage and suitability for women, due to potential side effects like unwanted facial hair growth.
What should I do if I experience side effects?+
If you experience any concerning side effects, such as scalp irritation, itching, or unexpected hair growth, stop using the product. You should report side effects to the MHRA via the Yellow Card scheme. For medical advice, contact NHS 111 or consult your GP, who may refer you to a dermatologist if necessary.
How do I compare the cost effectively?+
To compare the cost effectively, always look at the cost per month rather than the upfront price of a single pack. Consider multi-pack deals, subscription services, or own-brand options like Superdrug's, as these can often provide better value over time.
