Clascoterone, sold as Winlevi, is a topical anti-androgen cream approved for treating acne. It blocks androgen receptors in the skin to reduce oil production and inflammation. It is not yet an approved treatment for hair loss, though researchers are studying it for androgenetic alopecia.

# Clascoterone (Winlevi) Explained: Acne Treatment and Hair Loss Research

## What Is Clascoterone and What Is It Approved For?
Clascoterone is a topical anti-androgen medication that blocks androgen receptors in the skin. The approved product is Winlevi, a 1% prescription cream used to treat acne. It works locally rather than throughout the body, which sets it apart from oral anti-androgens. This local action is also why researchers are studying it for other androgen-related concerns, including oily scalp and pattern hair loss.

## How Does Winlevi Work on Acne?
Acne develops from a mix of clogged pores, bacteria, inflammation, and excess sebum. Androgens increase sebum production, which can worsen breakouts. Winlevi blocks androgen receptors in the pilosebaceous unit, reducing oiliness and inflammation over time. Most patients use it alongside a cleanser, moisturizer, sunscreen, and other prescribed topicals as needed.

## Is Clascoterone a Steroid Cream?
Clascoterone is a steroidal molecule chemically, but it does not function as a corticosteroid. Corticosteroids such as hydrocortisone and betamethasone calm immune-driven inflammation in conditions like eczema. Clascoterone instead blocks androgen receptors. It is not a substitute for corticosteroid therapy and is not prescribed for that purpose.

## What Are the Side Effects of Clascoterone?
Most reported side effects are local and mild to moderate: redness, dryness, itching, burning, or peeling at the application site. These reactions are common with topical acne treatments in general, especially early in treatment. Systemic absorption stays low when the cream is used as directed. Patients applying it to large areas, using occlusive dressings, or combining it with other strong topicals should follow dosing instructions closely.

## Can Clascoterone Treat Hair Loss?
In androgenetic alopecia, dihydrotestosterone (DHT) gradually shrinks susceptible hair follicles. Blocking androgen receptors on the scalp is the theory behind clascoterone's hair loss research, and clinical studies are underway. Winlevi 1% is currently approved for acne only, not for hair regrowth. Patients with thinning hair should get a clinical diagnosis before choosing a treatment plan.

## What Hair Loss Treatments Are Proven Instead?
Topical minoxidil is an established first-line option for androgenetic hair loss. For appropriate patients, finasteride or dutasteride are oral prescription options that reduce DHT systemically. Clascoterone has no hair loss approval yet, so its use for that purpose stays investigational. A clinician can help decide which option, or combination, fits a specific diagnosis.

## How Does Diagnosis Affect Hair Loss Treatment Choice?
Pattern hair loss, telogen effluvium, traction alopecia, and inflammatory scalp conditions can look similar but need different treatment strategies. At Hair Center of Turkey, diagnosis comes before any treatment recommendation. If hair loss is androgen-driven, medical therapy may stabilize shedding and protect existing follicles, which matters even for patients who later choose a hair transplant.

## Frequently Asked Questions

### Is clascoterone a steroid?
Chemically, clascoterone is a steroidal molecule, but it is not a corticosteroid. It does not calm immune-driven inflammation like hydrocortisone or betamethasone. Its action is anti-androgenic, blocking androgen receptors in the skin.

### What does clascoterone do for skin?
It blocks androgen receptors in the pilosebaceous unit, reducing sebum production and inflammation. This is the mechanism behind its approved use for acne. Most patients see gradual improvement over weeks as part of a broader skincare routine.

### How is clascoterone different from finasteride?
Clascoterone is a topical cream approved for acne, acting mainly at the skin. Finasteride is an oral medication approved for androgenetic hair loss that lowers DHT systemically. Clascoterone has no approved hair loss indication, while finasteride does.

### Will clascoterone regrow hair?
There is no approved indication for hair regrowth yet. Research is exploring whether blocking scalp androgen receptors can help androgenetic alopecia, but results are not established enough for approval. Winlevi remains approved only for acne.

### Is clascoterone better than minoxidil?
This comparison cannot be answered yet since clascoterone has no hair loss approval. Minoxidil has decades of clinical use and established results for androgenetic hair loss. Clascoterone for hair loss remains investigational.
