Rx Hair: Prescription Hair Loss Treatment in Irvine, Orange County, CA

Rx Hair is a physician-supervised treatment plan for patients experiencing hair thinning, hairline recession, or pattern baldness. At Spectrum Skin Clinic in Irvine, we offer clinical-strength prescription medications like oral finasterideand topical minoxidil to help slow hair loss, stimulate regrowth, and maintain long-term hair health. These medical therapies can be used alone or as part of a comprehensive hair restoration strategy.

What is Rx Hair and how does it work?

Rx Hair refers to prescription-based treatments for hair loss—designed to correct hormonal or vascular imbalances that contribute to hair shedding. The two most common FDA-approved options are:

Finasteride (Propecia) – A daily oral medication that blocks DHT, a hormone linked to male pattern baldness. It helps slow or stop hair loss and can stimulate regrowth, especially at the crown and mid-scalp.

Topical Minoxidil – A vasodilator that improves blood flow to the scalp and lengthens the growth phase of hair follicles. Applied directly to thinning areas, it supports healthier, thicker hair over time.


We provide clinical-grade versions with higher potency or custom compounding when appropriate.

What can I expect during treatment?

After a detailed consultation and scalp evaluation, we prescribe a tailored medication plan based on the type and severity of your hair loss. Most patients use a daily oral or topical medication at home, with regular follow-up to monitor progress and adjust treatment as needed.


We also offer combination therapy—adding growth factors, exosomes, or PRFM for patients who need more aggressive results.

When will I see results, and how long do they last?

Most patients begin seeing reduced shedding within 6–8 weeks, with noticeable regrowth around 3–6 months. Optimal results may take up to 12 months. Continued use is necessary to maintain results, as discontinuation may lead to resumed hair loss.

Are there any side effects or risks?

Finasteride may rarely cause sexual side effects in men, which are usually reversible upon stopping the medication.

Minoxidil may cause scalp irritation or shedding when first starting treatment (a normal part of the cycle).


We monitor your response closely and adjust treatment as needed.
