How Does Hims Minoxidil Finasteride Spray Work?

Before we outline the best way to apply it, let’s break down how Hims hair spray works to regrow hair.

Hims spray contains two clinically proven active ingredients: minoxidil and finasteride. Both are FDA-approved for hair loss, but they work differently.

Finasteride works to reduce DHT in the scalp. DHT, or dihydrotestosterone, is the male sex hormone responsible for a genetic form of hair loss known as androgenetic alopecia — also referred to as male pattern baldness, or male pattern hair loss.

Minoxidil solution (the generic name for over-the-counter medication Rogaine®) promotes hair regrowth by stimulating dormant hair follicles, encouraging hairs to return to the growth phase of the hair growth cycle, and increasing blood flow to the scalp.

Combined, the two ingredients are a powerful force against hair follicle dysfunction.

How Do I Apply Hims Topical Finasteride & Minoxidil Spray?

Follow these steps when applying Hims spray for optimal hair growth results.

1. Spray the Product On Your Scalp

Before you pick up the bottle, part your hair slightly, so the solution can better reach the scalp. Apply the spray by holding the bottle two to three inches away from your head.

When spraying, target the four main zones of hair loss, including:

  • The crown of the head

  • The top of your head

  • Each side of the front of the head (commonly the first place where hair begins to recede)

Even if you’re not currently experiencing hair loss across your scalp, applying the spray to all areas of the head can help prevent hair loss from spreading and creating bald spots.

While it may seem like you need more sprays, the formula is designed to restore hair health without the need to fully soak your head.

2. Rub and Repeat

Spray one spot at a time, gently massaging the solution into your scalp between sprays.

You may find application a little easier if you tilt your head back slightly while applying and massaging in the hair regrowth treatment. This will help prevent it from running down your forehead and getting into your eyes.

3. Let It Dry, and Wash Your Hands

It is important to let the treatment dry completely before you go back to your regular activities — especially if you’re applying it before bed or before putting on a hat.

If you apply the Hims hair spray at night, it’s OK to wash your hair in the morning since the treatment will have had enough time on your scalp to be effective.

Always make sure to wash your hands after applying Hims spray.

And as a safety tip, note that topical finasteride isn’t safe for pregnant people (or people who are trying to become pregnant). If that applies to your partner, avoid sharing a pillow with them, and be cautious about potential exposure.

4. Be Patient

While Hims spray starts working right away, it can take between three and six months to see visible results.

If your hair looks the same after three months, consider it a success — that means the hair loss hasn’t progressed.

Ultimately, consistency is key. Regularly applying Hims spray and following your healthcare provider’s medical advice will ensure hair growth results are on the way and thinning hair is on the way out.

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 About Hims Spray?

Here are a few things to keep in mind throughout your treatment with Hims hair growth spray:

  • Your hair care routine is important. Taking good care of your scalp while you use Hims spray will help encourage healthy hair growth. If you’re experiencing any flaking or itchiness, our Dandruff Detox shampoo can help.

  • You won’t wash away results. Unless you wash off the solution straight after applying, washing your hair regularly won’t impact the product’s effectiveness. Washing will actually help remove build-up that can prevent the solution from being fully absorbed by the scalp.

  • You may experience some initial shedding. Minoxidil helps promote new hair growth by making room for healthy new strands. Mature strands may shed during this process. But don’t worry, it’s temporary.

A Quick Note About Side Effects

Hims topical solution contains FDA-approved hair loss medications and isn’t likely to produce side effects. But some scalp itching and dryness can happen early on.

It’s important to use the treatment as directed by a medical professional. Spraying more than directed won’t make it more effective and actually can increase your risk of side effects.

If your side effects get worse the longer you use the spray, reach out to your prescribing provider or a dermatologist.

Bottom Line: How to Apply Hims Spray

Tackling hair loss doesn’t have to be complicated. Hims minoxidil finasteride spray makes treating hair loss simple and stress-free.

Here’s a recap of how the treatment works:

  • Apply the spray to all areas of your scalp. Targeting your whole head when you use the product can prevent further hair loss.

  • Don’t apply more than you need. More isn’t always better, and with this type of hair loss medication, too much of the solution can increase your risk of side effects like itching and irritation.

  • Take care of your hair. A solid hair care routine will ensure your scalp and hair follicles are primed for new, healthy hair growth. Other products, like hair thickening shampoo and Biotin supplements, can also help on your path to healthier, fuller hair.

  • Know that it can take time to see results. Hims spray won’t produce instant hair growth, but with a little patience, you’ll see a visible difference.
