How Does Propecia Stimulate New Hair Growth?

How Does Propecia Stimulate New Hair Growth?

Does your receding hairline make you feel unattractive? While many men rock the bald look, it might not be for you. That’s why finding a hair restoration treatment that’s safe and effective is important to replenish your confidence. 

Hair transplants may offer dramatic results, but not everyone wants to go under the knife or has the income to do so. Luckily, a medication can restore your hair count to its original state.

Propecia® is an oral medication taken daily that increases hair growth and halts future hair loss for a full, healthy head of hair. Peter Panagotacos, MD, and his team at Hair Doc provide Propecia to patients in the Cow Hollow neighborhood in San Francisco, California, to get a natural but younger-looking you.

How the three hair cycles work

You’ve probably noticed hair strands on your pillow and comb, no matter your age. That’s a normal part of hair growth and can be tied to its three phases — anagen, catagen, and telogen. 

The anagen phase describes the active growth period of your hair. During the catagen phase, your hair halts its growth and separates from the follicle. The telogen phase contains a rest period of 2-3 months before the hair falls out.

The average person sheds 50-100 strands of hair each day. But as you get older, your hair cycle can become disrupted or impaired, and your hair may start to fall out more quickly. This results in unwanted changes like a receding hairline, bald patches, or thinning hair.

80% of men retained their original hair count

Propecia isn’t a new medication. It was first developed in 1992 to treat prostate gland enlargement and was approved five years later for hair growth. Now more than 9 million men take Propecia annually for a good reason — it works. But how?

Most cases of balding in men are classified as androgenic alopecia. Androgenic alopecia is caused by a decrease in DHT, an androgen produced in your body linked to testosterone. 

Propecia works by decreasing your body’s natural DHT. DHT is thought to attach hair follicles, shrinking and shortening hair and causing it to fall out. This stimulates hair growth and slows hair loss for a whole head of hair again.

In a clinical study, 80% of men who took Propecia retained their original hair follicle count.


You only get one body in this life. That’s why treating it with the best care possible is important. 

While hair transplants are a popular method to get fuller hair, it involves making small incisions and a recovery period that doesn’t suit everyone’s needs. That’s why the appeal of oral medication can be a better alternative for many men. 

Benefits of Propecia include:

Talk to Dr. Panagotacos or your primary care physician to see if you’re a good candidate for Propecia.

When will I see the results?

Propecia is one of the most reliable and effective treatments for improving your hairline. While it provides fuller hair, it’s important to understand that the results aren’t immediate. 

The moment you start taking Propecia, it starts blocking DHT right away. Because the hair cycle is slow and has three phases, patients taking Propecia generally notice new hair growth around the 3-4 month mark if they’re consistent in its use.

More dramatic results are experienced at six months with thicker and longer locks. By the one-year mark, your full results have set in, and all you need to do to sustain them is continue taking the pill.
