Finasteride & Thinning Hair Treatment

Finasteride & Thinning Hair Treatment

Finasteride is primarily designed to halt the progression of hair loss. Finasteride is most efficacious at the crown and vertex areas of the scalp, and generally does not affect the frontal scalp. Starting Finasteride early is the key to its success. 

Method of Action: The enzyme 5-alpha-reductase is involved in the conversion of testosterone into its active form of dihydrotestosterone (DHT – the androgen primarily responsible for male pattern baldness). Over time, DHT shrinks hair follicles until they no longer produce visible hairs. Finasteride is a 5-alpha-reductase inhibitor. By reducing circulating levels of DHT, androgen receptors in the hair follicle are protected from its adverse effects.

Usage: Finasteride is generally administered in the form of once daily pills. Results are not typically visible for period of about 6 months (with optimal results occurring around 12 months). After a period of 5-6 years, these results steadily diminish.

How Finasteride Works: Starting Finasteride early is the key to its success. Often at the first sign of hair loss, patients ask their doctor about starting a regimen that includes Finasteride pills like Propecia or Proscar. Although new hair growth will not be visible, it is important to remember that Propecia aims to stop hair loss from becoming worse (i.e. it does not aim to regrow hair). The treatment needs to be taken life-long as patients who quit Finasteride, thinking that it has not provided any results, often lose a great amount of hair shortly after discontinuing regular use.

The combination of topical minoxidil and finasteride is popular because both treatments can be used in synergy. Minoxidil and finasteride work in different ways; minoxidil stimulates hair growth by opening inactive potassium channels and finasteride blocks the negative effects of DHT. Together, these effects can produce noticeable results but one should be aware of the side-effects finasteride can come along with.

Side-effects of Finasteride: All medicines may cause side effects, but many people have no, or minor, side effects. Check with your doctor if any of these most common side effects persist or become bothersome when using Finasteride: decrease in libido, low sperm count, and a decrease in general vitality.
Some serious side-effects include:
- changes in breasts (lumps, pain, etc.)
- allergic reactions (itching, rash, hives)
- testicular pain
- permanent sexual dysfunction
