What is Propecia?

Propecia is a hair loss medicine containing the active ingredient Finasteride. Propecia is the original brand name version of the medicine that prevents further loss and assists in regrowing hair in men with male pattern baldness. It's a treatment that is best used during the progression of male pattern baldness before it progresses to full baldness.

How does it work?

Propecia works by blocking the conversion of testosterone to dihydrotestosterone (DHT), a hormone that heavily contributes to male pattern baldness. Lower DHT levels in the scalp allow hair loss to stop and hair to regrow. Because DHT is primarily a male hormone Propecia has only been proven effective and used in men. Propecia/ finasteride works only on the scalp not the rest of the body.


Propecia successfully prevents hair loss in men 90% of the time. 50% of men will experience increased hair growth in areas that were previously losing hair. It is only effective in men who still have live hair follicles and will not be effective if the baldness has progressed too far.

Visible improvement can take 3-6 months of continuous use. If treatment is ceased, hair loss may resume within 6-12 months.

How to take Propecia

Take ONE tablet daily. It may be taken with or without food.

Hair growth and hair follicle recovery is a gradual process, it can take 3 to 6 months before results are noticed. Stopping Propecia can result in a reversal of effects within 6 to 12 months, so it is important you continue to take this medication to retain benefits.

Is Propecia more effective than Regaine?

Regaine is a product that is applied directly to the scalp 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! Furthermore, with Propecia, more men 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.

These treatments may be used in combination and many men will use both treatments to treat hair loss and maximise hair regrowth.


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. This is most effective if the hair follicles have died and can no longer regrowth with drug treatments. It may be recommended by your surgeon to take Propecia or use Regaine, as the implanted hair may follow the behaviour of the source hair. Laser therapy is also advocated as a hair loss treatment and displays a positive outcome for many men.

Propecia vs Finasteride

Yes, if there are live hair follicles in thinning areas, it will help to stimulate growth in them, thickening the appearance of the hair.

There are some common myths about hair loss, some which have some basis in fact, and others which are just a little ridiculous! To clarify some of the common myths and misconceptions about hair loss, we have compiled a list of the ones we hear most often.

  1. Pluck One Grey Hair And Two Grow Back – This hair loss myth has floated around for the longest time. However, it is not true that if you pluck a grey hair, two will grow back!
  2. Standing On Your Head Makes Your Hair Grow  – We told you some are a little ridiculous! Despite this being  a commonly heard myth, we have confidence that you have never spent long periods on your head in the hope of some hair growth! The myth is routed in the false belief that blood flow to the head will help hair growth. However hair loss is not a blood flow problem, but generally linked to sensitivity to dihydrotestosterone.
  3. There’s No Cure For Baldness – From the incredibly optimistic, to the ultra pessimistic. While there is no “miracle cure” that is going to work for everyone, and bring back your hair to it’s most lush, there are certainly many successful treatments. Laser therapy and hair transplant have the highest success rate, although are on the expensive end of treatment. Drugs like Propecia is a successful treatment of hair loss, and other shampoos and lotions (such as Regaine) can also help stop or reverse hair growth in milder cases of hair loss.
  4. Hair gel and hairspray can cause hair loss – Nop! There is no evidence to suggest they can cause balding. Also in this category of myth, over shampooing, or washing do not cause hair loss either. However, the grain of truth in the myths are that over-mechanical utilisation of hair, can weaken it. So things like using curling irons, or constantly pulling at your hair, can lead to acceleration of existing hair loss.
  5. Hair loss is  from your mum’s side of the gene pool – While  the primary baldness gene is on the X chromosome (the one men inherit from their mothers), research suggests that men who have a bald father are more likely to develop male pattern baldness than those who don’t.
  6. Higher Testosterone Linked To Hair Loss – The inherited problem is a sensitivity to DHT (dihydrotestosterone). It is this that can cause hair loss in men and some women. However taking synthetic testosterone can accelerate hair loss in men.
  7. Hats Cause Baldness – Nop! They Don’t! So whether you wear a baseball cap, or a bowler hat, you can dig it out of the cupboard again.
  8. I Can Grow Back Dead Hair Follicles – Unfortunately not. Once they’re gone, they’re gone. Medication like Propecia, or laser therapy, can help hair follicles become thicker and healthier, but the only option for regrowth is a hair transplant.
