The everything spray
Four hair-loss actives, one spray
The FaroRx 4-in-1 hair spray combines topical finasteride (blocks DHT), minoxidil (stimulates growth), tretinoin (boosts absorption) and fluocinolone (calms the scalp) in one 60mL daily spray. Topical delivery means lower systemic exposure than oral tablets. It starts at $119 per month.
What is 4-in-1 Hair Spray?
This compounded spray puts four complementary actives in one bottle: finasteride to block DHT at the scalp, minoxidil to stimulate growth, tretinoin to increase penetration and follicle response, and fluocinolone, a mild anti-inflammatory that keeps the scalp calm and reduces topical irritation.
Dosing
Apply the prescribed number of sprays to the affected scalp areas once daily, on dry or towel-dried hair. One bottle lasts a month.

How 4-in-1 Hair Spray works
Finasteride, topically
Blocks DHT right at the follicle with significantly lower blood levels than the oral tablet.
Minoxidil growth signal
Extends the growth phase and improves follicle blood supply.
Tretinoin multiplier
Increases skin penetration and has its own evidence for boosting minoxidil response.
Fluocinolone comfort
A mild steroid that calms scalp inflammation and reduces irritation from the other actives.
Side effects, honestly
Every medication has tradeoffs. Here's what to know before you start — your provider reviews your full history before prescribing.
- Mild scalp dryness or flaking at first
- Because it is topical, systemic side effects are far less likely than with oral tablets
- Initial temporary shedding is normal

4-in-1 Hair Spray questions
What is in the 4-in-1 hair spray?
Topical finasteride (blocks DHT), minoxidil (stimulates growth), tretinoin (boosts absorption and response) and fluocinolone (calms the scalp). Four mechanisms, one daily spray.
Is topical finasteride safer than oral?
Topical application produces significantly lower blood levels of finasteride, so systemic side effects are less likely — which is why many men concerned about oral side effects choose the spray. Efficacy for scalp DHT reduction is comparable in studies.
Is the spray as effective as oral tablets?
For most men, the combination of four actives topically is at least comparable to oral finasteride plus topical minoxidil — with better adherence because it is one step.
How long until I see results?
Shedding slows within 2-3 months; visible density improvement typically takes 6-12 months of daily use.
Can I use the spray with oral treatments?
Usually one finasteride source is enough — most patients use the spray alone or combine it with oral minoxidil. Your provider will design the regimen.
How much does it cost?
$119 per month for the 60mL spray, including provider review and free shipping.
