Description
What is Finasteride 0.2% Topical Spray?
Finasteride 0.2% spray is a compounded topical formulation off-label for male pattern hair loss. Unlike the oral tablet, it acts locally at the scalp, reducing DHT in the follicles with lower systemic absorption. It is an unlicensed medicine where clinically appropriate by a UK-registered specialist.
How does it work?
Finasteride inhibits 5-alpha reductase, reducing the conversion of testosterone into DHT. Applied to the scalp, it acts locally at the hair follicle, promoting follicle recovery and healthier hair growth, with less impact on DHT levels throughout the rest of the body than oral Finasteride.
Topical vs Oral Finasteride — Key Differences
- Acts locally on the scalp with lower systemic DHT suppression
- May offer a reduced systemic side effect profile
- Applied directly to affected scalp areas once daily
- Suited to men with concerns about systemic side effects
How to use
Apply to dry scalp in affected areas once daily, usually in the evening. Part the hair, apply evenly, allow to dry before styling. Wash hands after use.
How long does it take to work?
Stabilisation of hair loss is typically noticed within 3–6 months of continuous daily use, with peak benefit at 2 years. Treatment must be maintained every day — stopping will lead to reversal of benefits within 9–12 months.
Who should not use this?
- Women
- Anyone under 18
- People with liver problems
- People with urinary retention issues or prostate issues
- Anyone allergic to Finasteride or its components
Pregnancy warning
If your partner is pregnant, they must not handle the spray or contact treated areas until dry. Use condoms during treatment as traces of Finasteride may be present in semen.
