Hey - You've only had Locklab for a few months. Want to give it some more time?

Locklab typically takes up to 6 months to see initial results, and up to one year to see maximum improvement (although the majority of men see results between 4 and 9 months). If you stop taking it, you’ll lose the progress you’ve made, and your hair loss will likely continue.

Sexual symptoms may go away after a few days or weeks

According to the FDA, approx. 69% of men who report sexual side effects from 1mg of finasteride (Locklab contains 1.1mg), keep taking the drug. We have found that this is likely because symptoms often go away after a few days or weeks for our patients.

Why finasteride may cause sexual dysfunction in men

How common are sexual side effects?

According to the FDA, in clinical trials, 1.2% of men discontinued finasteride due to sexual side effects, compared to 0.9% of men taking a placebo. So if the same percentage of men in the finasteride group also incorrectly attributed side effects to finasteride, then the total proportion of men who stopped treatment would be only 0.3%. (Source)

What’s happening in my body?

When you increase your testosterone, as with testosterone therapy (trt), you always increase your estrogen slightly. That's just how the body works because some testosterone is always a aromatizing into estrogen, so more testosterone means more estrogen. So perhaps you were an uncommon case where the increase in estrogen affected you negatively. According to the FDA, approx. 0.3% of men stop taking finasteride due to sexually adverse effects that are possibly or likely drug related.

Is finasteride causing my ED?

18.4% of guys in the US suffer from sexual dysfunction like ED and loss of libido without taking finasteride, so it is very difficult to determine how finasteride is affecting you except for in a controlled clinical trial. Every double-blind placebo controlled trial (clinical trials that eliminate bias) has found a very small or nonexistent percentage of men with sexually adverse effects from finasteride.

Does sexual dysfunction go away?

For men who never take finasteride, sexual dysfunction can last for months, years, or life. ED is nasty and not relegated to something caused by drugs.

According to Harvard Medical School, some men report persistent sex drive and ejaculation problems after stopping the medication. This is not proof that finasteride is to blame, since a variety of medical conditions and other prescription drugs could explain the sexual symptoms.

Do you understand you will still shed hair while taking any hair loss medication?

Locklab does not prevent shedding, it prevents balding. Like all mammals (dogs, cats, etc.), shedding hair is a healthy part of the hair growth cycle and is “hair fall” (with replacement) and not “hair loss” (without replacement). Shedding can even signal that your hair is entering a new growth phase.

Hair loss treatments don’t prevent shedding, they prevent balding

If you’re still experiencing hair shedding after using Locklab, congrats, you're an alive human man. Like with all mammals (dogs, cats, horses, etc.) shedding hair is a healthy part of life. But just like dog hair on the couch isn't cause for alarm, hair shedding isn't the same as hair loss.

Here's what you need to know about shedding vs. balding.

You'll shed a little more hair at first

When you become responsive to a hair growth treatment, you’ll likely go through a shedding phase where you notice more hair falling out. This is not a negative sign, it’s actually a very positive sign that treatment is working—pushing out your old, thin hair to make room for new, thicker growth. Don't worry! You're not going to lose a head full of hair, you'll just shed more than normal. This usually lasts 4-6 weeks and is “hair fall” (with replacement) and not “hair loss” (without replacement).


You'll continue shedding hair at a normal rate

While taking Locklab, you should expect to still shed hair, the medication only works to prevent you from losing it permanently. Shedding often comes in cycles and doesn’t mean you're going bald—it can even signal upcoming hair growth. We know shedding can be worrisome, but remember, the typical amount of normal hair shedding is 50-100 hairs per day.

Locklab works to prevent permanent hair loss

Locklab treats male pattern baldness (androgenic alopecia) also known as hair miniaturization, where hairs gradually become thinner over time and eventually die. This is what we usually think of when we say someone is going bald.

Locklab is constantly fighting against hair miniaturization by partially blocking the conversion of testosterone into dihydrotestosterone (DHT) - the hormone that's attacking your hair follicles and causing them to miniaturize.

While male pattern baldness is the cause of 95% of hair loss in men, a few men may also be experiencing additional temporary hair loss called telogen effluvium. This is when you lose hair from stress, nutritional deficiencies, hormonal changes, or other factors. Unfortunately, this can occur in addition to genetic hair loss. Fortunately, this type of hair loss resolves on its own in most cases. Although; your genetic hair loss will still continue unless treated.

“The normal range between [healthy] people of daily shedding is between 50 - 100 hairs per day”
—Dr. Russel Knudsen, Past-President ISHRS


How to tell if your treatment is working


Losing hair from male pattern baldness is a gradual process. Remember, Locklab on its own cannot make your hair fall out faster, and most hair shedding while taking Locklab is temporary.

Take these steps to figure out if there's an issue that needs to be addressed:

1. Take photos of you hair, in good lighting, from a few different angles
2. Wait a 2-3 months and take new photos at the same angle in the exact same lighting (the same lighting is extremely important)
3. Compare the photos to see if your hair is actually falling out without being replaced

If it's clear that your hair loss is getting worse (you are becoming more bald), message your Locklab physician about what the best treatment options may be for you going forward.
