Minoxidil – Overview

Rogaine is a renowned brand which has Minoxidil as its core and main active ingredient. Minoxidil has been around for some years as a solution applied to the scalp to arrest or, in some cases, reverse hair loss. Rogaine is a trademark of Upjohn Pharmacia Pty Ltd. The active ingredient of Rogaine is minoxodil, which was originally prescribed in tablet form for the treatment of high blood pressure. As well as reducing blood pressure, it was found to grow hair on the scalp. Unfortunately it also induced hypertrichosis, or hair growth on the face, shoulders, arms and legs of women and on the entire body of men.

While growth of hair on the scalp was seen as an encouraging side-effect, the collateral growth everywhere else was unacceptable. This resulted in the delivery system being changed to a solution applied topically to the localised area where hair growth was desirable. This solution is what is now currently available worldwide over the counter at pharmacies, as a 2 per cent or 5 per cent Rogaine solution. Additional common brand names include Regaine and Hair A Gain.

Frequently Asked Questions

How does Minoxidil work?

We know Minoxidil works, but we are unsure of the exact reasons why it works. We know that Rogaine is a powerful vasodilator, effectively increasing the blood flow to the scalp; however, the positive growth aspects occur irrespective of this. There are many credible theories. It is known that the use of Rogaine holds the hair in the anagen or growing phase longer, warding off the catagen or destruction of the follicle phase.

How effective is Minoxidil for Hair Loss

The best results with Rogaine have been achieved by patients in their twenties with a recent onset of hair loss, and a small area of loss. A cosmetically significant improvement in regrowth occurs in less than 10 per cent of patients. However, a larger percentage have found that with continued use it is possible to stop further loss in the short term. However, in the long term, hair loss generally continues.

How to use Minoxidil for Hair Loss

Rogaine is administered in a liquid form of varying strengths from 2 per cent to 5 per cent. The recommended dosage is twice-daily applications of 1 ml to the areas affected by hair loss. It is available without prescription from pharmacists. Some pharmacists have a generic form available with added tretinoin. The tretinoin acts as a surface irritant, helping the absorption of the Rogaine into the skin.

Side Effects of Minoxidil for Hair Loss

Minoxidil has been shown to cause the following side-effects in some people:

  • Hypertrichosis: Strong hair growth has been seen in the forehead and eyebrow region and in some cases new hair growth on the tip of the nose has been noted.
  • Scalp Irritation & Itching; Inflammation and redness of the scalp, which can be exacerbated by the inclusion of tretinoin in the solution.
  • Irregular Heartbeat; Due to Rogaine’s vasodilating effects, people with heart problems or on blood-pressure medication should consult
    their doctor before using it.

Is it an effective medication like the PRP?

No. The Minoxidil is not as effective as the Finasteride or PRP.

Can both men and women use Minoxidil?


Does it need any prescription?

No. It doesn’t require any prescription like Finasteride does.

Is the trial pack valuable?

No. Using a trial pack will only be a waste of your money, for this medication to work consistant and regular applications are required over a sustained period of time.
