Propecia Hair Loss Tablets Online

You can request to buy Propecia (or the generic, Finasteride 1mg) online from our Online Doctor. You just need to fill in an assessment form so we can see if Propecia is suitable for you. Once you have completed your order, our doctor will review to see if a prescription can be issued. If approved, this will be passed to our UK registered online pharmacy, to dispense and dispatch your medication. If for any reason your order for Propecia is not approved, you will receive a notification and full refund on your order.

Generic Propecia

Propecia’s active ingredient is Finasteride 1mg. Knowns as 'Generic Propecia', Finasteride is available generically, saving you money on your treatment. This is because Propecia is the original branded version of the drug. Usually, the original brands are more expensive than their generic counterparts. It should not be thought however that the generic version is less effective. Medically, both Propecia and Finasteride 1mg are the same.

About Propecia

What does it do?

Propecia works by preventing testosterone from being converted to the hormone dihydrotestosterone (DHT). This allows the hair follicles to regain their normal size. Studies have shown Propecia can increase hair growth, and can also improve how people think their hair looks. It can take three to six months of treatment with Propecia before an effect is seen, and improvement may be seen for up to 5 years after you start taking it. Unfortunately, however, the balding process usually resumes within six to 12 months if treatment is stopped. 

Why use Propecia?

Men with male pattern baldness will usually look to use Propecia if their confidence or self-esteem has been affected by their hair loss. As Propecia is very effective medication, it is commonly prescribed by GPs for men looking to reverse the balding process. Studies have shown that men who have taken Propecia for 5 years, have around a 90% chance of having more hair, or not having lost any more hair. By comparison, in a control group, 25% of men who were not taking Propecia showed the same results

Side effects for Propecia are uncommon. The side effect of most concern to many is that one in 100 men who take Propecia experience a loss in sexual appetite (libido) or erectile dysfunction when taking the drug.

How effective is it?

9 out of every 10 men using Propecia will stop losing their hair when taking the medication. Approximately 1 in 2 men will see their hair regrow in the areas where they were losing it. Studies were made in men aged 18-41 with mild to moderate hair loss. On stopping Propecia, hair loss will usually resume after six to twelve months.

How to take Propecia

ONE tablet of Propecia should be taken each day. It can take 3-6 months before full results are noticed. Stopping Propecia will result in a reversal of effects, so it is important you continue to take this medication to retain benefits.

It can be taken with or without food, so you don't need to worry about having a meal. 

Propecia vs Regaine

Propecia and Regaine differ in a number of ways, from the mechanism of action to dosage form. Regaine is a topical application that achieves results in around 60% of men who use it. Meanwhile, Propecia has been shown to either improve or stop further hair loss in 90% of men! More men using Propecia find that they experience regrowth and improvement in their scalp hair coverage, as opposed to just maintenance of existing coverage. In comparison, 75% of men with male pattern baldness who did not take medication, showed more hair loss over the same period. 

Many men will use both treatments to treat hair loss and maximise hair regrowth.

What are alternative treatments?

Alternative treatments for hair loss include topical applications such as Regaine Foam, hair loss shampoos, and vitamin supplements.

Increasingly, men are also turning to surgical options, to implant hair. It may be recommended by your surgeon to take Propecia or use Regaine anyway, as the implanted hair may follow the behavior of the source hair. Laser therapy is also advocated as a hair loss treatment and displays a positive outcome for many men.


  • What is Propecia?

    Propecia (finasteride) is a prescription-only treatment. It’s not available on the NHS so you need a private prescription. Alternatively, you can make a private appointment with your GP. We can also generate this at no extra cost when you complete your online assessment, and pay for your treatment. It is only suitable for men and should never be taken by women.

    While there are no long term studies on the fertility of men taking propecia over an extended period of time, poor semen quality is listed as a possible side effect of Propecia.

    No - Propecia should be taken as directed. The daily dosage of Propecia is one tablet. (1mg).
