Hair Loss & Hair Thinning Treatment in Toronto

Male pattern baldness can occur in men over the age of 18. While there is no known cure, there are methods to curtailing the rate of hair loss as well as surgically restoring it. At Dr Paul C. Cotterill, we focus on providing hair restoration treatments, but can also provide advice on drug studies pertaining to male pattern baldness. Toronto men, for example, can try taking medication like Propecia or Minoxidil to prevent further hair loss and promote regrowth. It’s important to begin treatments as early as possible, so keep an eye out for hair shedding or thinning as these are early signs of male pattern baldness. If you suffer from male pattern baldness, Toronto-based Dr Paul C. Cotterill may be able to help. Contact our office to schedule for a consultation today.

Common Causes for Male Pattern Baldness

If your hairline is receding or your crown is thinning, it can be a sign of male pattern baldness. It affects most men at some stage in their lives and can lead to a receding hairline and a thinning crown. One of the common causes of baldness is a condition known as androgenetic alopecia otherwise known as male pattern balding.

Male pattern baldness often follows a predictable pattern and includes the following:

  • Hair starts to thin on top and around the temples

  • Hair starts to recede from the front of the hairline

Other causes of  scalp hair loss in men include:

  • Alopecia areata: Here, your body’s autoimmune system attacks healthy hair follicles, which leads to baldness, and your hair may fall out in patches.

  • Telogen effluvium: This condition leads to excessive shedding of hair and may be triggered by an accident, weight loss, or stress, but is often temporary.

  • Nutritional deficiency: Unhealthy food habits can lead to nutritional deficiency and further increase hair loss.

Treatments Available

There are a number of treatments available to address hair loss, including:


  • Medication: There are prescription and over-the-counter drugs. Usually, doctors may prescribe finasteride and minoxidil. Minoxidil is a topical treatment that is easily available at medical stores.

  • Low-level laser therapy: This treatment can help stimulate hair follicles. It is also less invasive.

  • Hair transplant surgery: A hair transplant is another way to help restore your hair and treat baldness.

Drug Study - Propecia & Minoxidil

Dr Cotterill has been an investigator for Merck Corporation. He was also involved in a press conference held in Toronto in June of 1998 to announce the passing of Propecia as a prescribed medication for the treatment of Male Pattern Baldness in Canada.

The following is a synopsis of the findings of a two-year drug study:

Propecia (Finasteride 1 mg) has just been given approval by the Health Protection Branch of Canada for release as a prescribed drug. This medication is marketed by Merck Frosst and is now available in pharmacies at approximately $1.50 per tablet. The two-year data from clinical trials involving 1,879 men with pattern hair loss involved 4 Canadian centers, of which Dr Paul Cotterill and Dr Walter Unger were the Ontario Investigators. The clinical trials were performed on men aged 18-41 with mild to moderate hair loss on the top of the scalp.

Results showed that there was no more hair loss in 83% of men after two years. Additionally, there was hair regrowth in 66% of men. This figure was broken down into 30% of men having mild regrowth, 31% having moderate, and 5% dense regrowth. This medication is very well tolerated, with less than 2% of men experiencing side effects. 1.8% experienced a mildly decreased sex drive, problems with erections, and decreased ejaculate volume. Propecia has also been very rarely associated with ongoing erectile dysfunction.   Dr Cotterill will discuss the benefits,  limitations and side effects of the drug to determine if Propecia is a proper fit for the patient.

 Additionally, you may take the medication before, after, and during hair transplants.
