Hair Treatment Powder Finasteride CAS 98319-26-7
Finasteride is a well-established 5α-reductase inhibitor widely used in pharmaceutical and dermatological research. It works by blocking the conversion of testosterone into dihydrotestosterone (DHT)—the key androgen responsible for androgenetic alopecia (male pattern hair loss) and benign prostatic hyperplasia (BPH).

Finasteride CAS 98319-26-7 Raw Powder | 5α-Reductase Inhibitor for Hair Loss & Prostate Health
Finasteride is a well-established 5α-reductase inhibitor widely used in pharmaceutical and dermatological research. It works by blocking the conversion of testosterone into dihydrotestosterone (DHT)-the key androgen responsible for androgenetic alopecia (male pattern hair loss) and benign prostatic hyperplasia (BPH).
Due to its proven efficacy, clear mechanism of action, and strong clinical background, Finasteride remains one of the most important active ingredients in hair loss treatment and prostate health formulations worldwide.

What is Finasteride?
Finasteride is a synthetic 4-azasteroid compound that selectively inhibits Type II 5α-reductase, the enzyme responsible for converting testosterone into DHT.
Since DHT plays a central role in:
- Hair follicle miniaturization
- Scalp hair thinning
- Prostate enlargement
Finasteride effectively addresses the root hormonal cause of these conditions rather than only treating symptoms.
Finasteride Mechanism of Action
DHT Suppression
Finasteride inhibits 5α-reductase, leading to:
- Reduced DHT levels in scalp and prostate tissue
- Decreased androgen-driven follicle miniaturization
Hair Follicle Protection
Lower DHT levels help:
- Preserve existing hair follicles
- Slow or stop hair loss progression
- Support long-term hair density maintenance
Prostate Volume Reduction
In prostate research, Finasteride:
- Reduces prostate size
- Improves urinary flow parameters
Finasteride Benefits
- Clinically proven DHT reduction
- Slows progression of androgenetic alopecia
- Preserves and stabilizes existing hair follicles
- Supports prostate health research
- Oral and topical formulation compatibility
- Well-documented safety and efficacy profile
FAQ
Q1: Is Finasteride suitable for topical research?
Yes. Low-dose topical formulations are widely researched to reduce systemic exposure.
Q2: How is Finasteride different from RU58841?
Finasteride reduces DHT production, while RU58841 blocks DHT binding at the receptor level.
Q3: Can Finasteride be combined with Minoxidil?
Yes. Combination research shows synergistic effects for hair preservation.
Q4: Does Finasteride affect testosterone levels?
It does not significantly reduce testosterone; it mainly lowers DHT.
