If you have been prescribed a topical hair loss spray at Harley Street Hair Transplant Clinics, applying it correctly is just as important as using it consistently. While the ingredients (finasteride, minoxidil, and azelaic acid) work together to help slow hair loss and support hair growth, proper application ensures the solution is applied effectively, reaching the scalp.
Overview
In this guide, we’ll explain how to apply your Topical Combination Hair Loss Spray, how much to use on a daily basis, when to apply it, and the best practices to help maximise your results. Remember: you’re much more likely to experience the benefits when you apply the topical fin/min spray correctly and consistently.
Step-by-Step: How to Apply Your Topical Hair Loss Spray
Applying the topical finasteride and minoxidil combo spray for hair loss is simple. It takes a few minutes to add it into your daily hair care routine and ensures you’re taking a clinically-proven medication to combat your hair loss. The application of topical finasteride is actually no harder than taking an oral finasteride tablet.
Step 1 – Start With a Clean and Dry Scalp
Before applying the topical solution to your head, both your hair and scalp should be clean and completely dry before application. If you have applied any wax, gel, fibres, or hairspray earlier in the day, you will need to wash and dry your hair.
If you have recently showered or washed your hair, wait until your hair and scalp are fully dry before using the spray. A wet scalp may dilute the solution, affecting absorption and efficacy.
Step 2 – Identify Your Areas of Hair Loss
Take a moment to locate the areas where you are experiencing hair loss. Male pattern baldness (androgenetic alopecia) affects both the temples and crown in men. So, be sure to assess your:
- Temples
- Hairline (central portion of the frontal third)
- Crown (vertex)
- Mid-section (common in diffuse DUPA hair loss patients)
If you have longer hair, gently part it with your fingers or a comb to expose the scalp.
Step 3 – Apply 4 Sprays Directly to the Scalp
Hold the spray close (5-10cm) to the scalp and apply a total of 4 sprays (1ml) across the affected areas of your scalp.
Try your best to distribute the sprays evenly rather than applying all four to one spot. So, if you’re experiencing hair loss on your hairline and crown, you should do one spray on each temple and two on your crown.
Remember, the goal of applying the topical solution is to ensure the medication reaches the scalp and not just the hair. The solution needs to be absorbed by the skin. So, solution that gets stuck in your hair is unlikely to be absorbed, making the medication less effective.
Step 4 – Massage the Solution Into the Scalp
Using clean fingertips, gently massage the solution into the scalp for around 30–60 seconds. If you have ever applied a hair mask or keratin cream treatment, it’s very similar!
This helps spread the medication evenly across the treatment area and improves contact with the skin where the active ingredients are absorbed. However, avoid rubbing aggressively, as this can irritate the scalp.
Step 5 – Wash Your Hands
Once you’ve finished applying the treatment, wash your hands thoroughly with soap and water. You may also want to put the spray back in your medicine cupboard or bathroom shelf.
This helps prevent accidentally transferring the medication to other parts of your body or to other people. Pregnant women should not take or handle finasteride. Minoxidil is also toxic to pets.
Why Correct Application Matters
Topical hair loss treatments are designed to work directly on the scalp. Unlike oral medications, they need to come into contact with the affected areas of the scalp to deliver their active ingredients effectively.
Think of it this way… oral tablets are systemically absorbed and have a generalised effect on the body. Topical solutions offer a concentrated burst of medication, allowing you to target a specific area. So, you need to apply the medication correctly, otherwise it is not going to be effective.
The complete topical hair loss spray contains:
- 0.1% Finasteride – this helps reduce the production of dihydrotestosterone (DHT), the hormone most commonly associated with male pattern hair loss. Topical finasteride prevents DHT from binding to the androgen receptors on your scalp.
- 10% Minoxidil – this increases blood flow to hair follicles and helps stimulate new hair growth. This prescription level dose of minoxidil helps make your hair follicles thicker and stronger.
- 2% Azelaic Acid – may help inhibit DHT activity within the scalp while supporting the overall effectiveness of the treatment. Azelaic acid also helps increase absorption through the skin.
Applying the solution to the hair rather than the scalp can reduce its effectiveness, so taking a few extra moments to apply it properly can make a significant difference over time.
What If You Miss a Dose?
It isn’t the end of the world if you forget to apply your spray one evening. All you need to do is apply your normal dose the following day. However, don’t apply a double dose to make up for a missed application.
Forgetting to take medication happens to us all. Hair loss treatment works through consistent, long-term use, so missing the occasional dose is unlikely to affect your overall progress.
How Much Hair Loss Spray Should You Use?
You should apply 1ml of the solution per day for the topical spray to be an effective means of slowing pattern hair loss. Your bottle contains 90ml, which provides a three-month supply when used as directed.
The recommended daily dose is 4 sprays (1ml) once each day. It’s a small amount, but clinically proven to be effective at stopping male pattern baldness in its tracks. Consistency is key, so aim to apply the same amount every day.
Using more than the recommended amount will not make the treatment work faster and may increase the likelihood of side effects. Likewise, using less than the prescribed dose may reduce its effectiveness.
When is the Best Time to Apply Topical Finasteride and Minoxidil Spray?
We recommend most patients apply their topical hair loss solution at night, before they go to bed. After application, the solution takes around 20-30 minutes to absorb fully into the scalp.
Applying it before bed allows plenty of time for absorption without needing to style your hair or head out during the day. We also recommend sleeping on a cheap pillowcase to prevent staining.
Evening application also makes it easier to establish a consistent daily routine, which is one of the most important factors in achieving a successful long-term result.
What Should You Avoid After Applying the Spray?
There are a couple of things to avoid straight after applying your minoxidil and finasteride spray. To allow the medication to absorb properly:
- Avoid washing your hair immediately after application.
- Allow the solution to absorb for around 20–30 minutes before lying down if possible.
- Avoid applying other scalp products immediately afterwards unless advised by your clinician.
- Try not to touch or scratch the treated area unnecessarily.
These precautions are important because topical hair loss treatments need time to penetrate the scalp and reach the hair follicles where they exert their effect. If you wash your hair too soon after application, the active ingredients may be rinsed away before they have had a chance to fully absorb, reducing the overall effectiveness of the treatment.
Additionally, lying down immediately or frequently touching the treated area can cause the solution to transfer onto pillows, bedding, or fingers rather than remaining on the scalp. This not only reduces the dose reaching the follicles but may also lead to uneven distribution across the treatment area.
How Long Does it Take to See Results?
Most patients will apply the topical solution for 12 weeks before seeing any results. The hair growth cycle takes time, so patience is essential. The medication is working hard in the background to stop your hairline recession or crown thinning from worsening.
You may begin noticing reduced hair shedding after several months of consistent use. Visible improvements in hair density and thickness often take 3 to 6 months, with continued improvement possible beyond this period.
It’s important to continue using the treatment as prescribed, even if you don’t notice immediate changes. Stopping treatment prematurely may allow hair loss to resume.
A Summary of Applying Topical Hair Loss Medication
Using your 0.1% finasteride, 10% minoxidil, and 2% azelaic acid topical spray correctly gives the active ingredients the best opportunity to reach your hair follicles and support healthy hair growth.
Remember to apply 4 sprays (1ml) once daily, target the affected areas of the scalp rather than the hair, gently massage the solution into the skin, and allow 20–30 minutes for absorption before going to bed. Combined with daily consistency and patience, correct application plays an important role in achieving the best possible results from your hair loss treatment.
FAQs
No. The medication should be applied directly to the scalp, where the hair follicles are located. Spraying only onto the hair reduces the amount of medication reaching its target. Hold your hair out of the way before spraying.
Yes, these application steps are suitable for most topical hair loss treatments. However, always follow the instructions provided with your own medication, as the recommended dose, application frequency, and absorption time may vary between brands and formulations.
You absolutely can try a derma-roller or microneedling pen as part of your hair loss prevention routine. However, it’s not essential. One thing to consider though is to avoid applying your topical medication immediately after microneedling, as this may increase the risk of skin irritation or side effects.
No. The prescribed dose is 4 sprays (1ml) once daily. Using more than directed is unlikely to improve results and may increase the risk of side effects.
Either is acceptable, but evening application is generally recommended because the solution takes around 20–30 minutes to absorb, making it convenient to apply before bed. The solution doesn’t leave a greasy residue like some foams. So, you can apply the medication in the morning if you prefer.
Yes. After spraying, gently massage the solution into the scalp using your fingertips to ensure even coverage and good contact with the skin. It is not essential, but is likely to increase the efficacy of the medication.
In most cases, topical hair loss medication should be avoided for at least 24 hours after PRP to allow the scalp to recover and reduce the risk of irritation. After that, you’re fine to start applying the topical hair loss spray onto your scalp.
Do not apply topical hair loss medication until your hair transplant surgeon advises it is safe to do so. At Harley Street Hair Transplant Clinics, we recommend applying topical hair loss medication 4 weeks after your procedure. This gives ample time for your scalp to recover after surgery.
