How does our topical finasteride spray work?

This spray is a mixture of two clinically-proven ingredients to treat hair loss—finasteride and minoxidil. Finasteride reduces DHT (the hormone that causes hair loss in men) in the scalp and stops more hair from falling out while minoxidil promotes hair growth by reactivating dormant follicles.

How do I apply topical finasteride & minoxidil spray?

Follow these steps once a day and you’ll be good to grow.

1. Spray it on
  • Hold the bottle 2 to 3 inches from the head, parting the hair slightly so the solution can reach the scalp, and spray only the prescribed number of sprays divided across the 4 main zones of hair loss:
      ▪ the crown of the head
      ▪ the top of the head
      ▪ each side of the front of the head (where the hairline typically starts to recede)
  • While it may feel like you need more sprays, this formula is designed to work without having to drench the head.
  • Even if you’re not currently experiencing hair loss in all of these areas, it will often spread and affect them eventually. Applying the spray this way can help to prevent the spread.
  • Spray one zone at a time, massaging the solution into the scalp between sprays.
2. Rub & repeat
  • Once you’ve sprayed on the solution, massage it into the scalp. Repeat across the rest of the hair loss zones.
  • Quick tip, tip the head back slightly during steps 1 and 2 to avoid any solution running down the forehead.
3. Let it dry & wash hands
  • This is a scalp treatment, so be sure to let the solution dry so it can absorb properly into the scalp, especially if you apply before bedtime.
  • If you apply at night it’s ok to wash your hair in the morning, the treatment will have had enough time on the scalp to be effective.
      ▪ Another note to nighttime appliers: topical finasteride is not safe for women who are pregnant or trying to become pregnant—if that applies to your partner, do not share a pillow with them, and be careful to prevent their exposure.
  • Also, make sure you wash your hands well after you finish applying.
4. Practice patience
  • The solution starts working right away, but it will be at least 3-6 months before you start seeing the results.  If your hair looks the same after 3 months, that’s a success—you haven’t lost any more hair. Consistency is key so stick with it, and be sure to follow your provider’s recommendations. Results are on their way.

Is there anything else I need to know?

There are just a few more things to know before you get started.

  • Contrary to myths out there, you will not lose any extra hair by washing the scalp frequently so take good care of it while using this treatment. That means washing it (not just your hair) to avoid build up that could prevent the solution from properly absorbing into the scalp.

  • The minoxidil in this treatment helps kick start new hair growth and its first job is to make room for healthy new strands by shedding mature strands that were going to fall out anyway. Don’t be alarmed if you notice excess shedding when you start this treatment, it’s short term and isn’t usually noticeable for most people.

A quick note on potential side effects

  • Always use this treatment as directed by your medical provider, spraying more solution in more areas won’t make it any more effective and can increase the risk of side effects.  If you experience worsening side effects, reach out to your provider.

  • Emerging evidence show that topical finasteride has lower risk of sexual side effects than finasteride pills and does not create systemic changes in hormones.

  • Some itching or dryness of the scalp can occur early on as you get used to the treatment.
