Finasteride has long been one of the most widely prescribed treatments for hair loss – orally for men and as a topical for women and men. It plays a valuable role in slowing or stopping further hair loss and hair thinning. By targeting the hormone responsible for follicle miniaturization, finasteride (also known as Propecia) helps preserve existing hair and stabilize progression.
But finasteride alone doesn’t do everything.
To support stronger regrowth, healthier follicles, and better long-term outcomes, many patients benefit from pairing finasteride with red light therapy—especially when using a clinically designed, FDA-cleared device like the GroWell Red Light Therapy Hair Regrowth Cap.
Red light therapy—also known as low-level light therapy (LLLT)—has been clinically studied as a safe, non-invasive way to stimulate hair follicles and improve scalp health.
When red and near-infrared light reach the scalp, they help:
Unlike medications that focus on hormonal pathways, red light therapy works at the cellular level, supporting the follicle’s natural ability to grow thicker, stronger hair over time.
Because of this complementary mechanism, red light therapy pairs exceptionally well with finasteride.
Finasteride and red light therapy address different—but equally important—parts of the hair loss process.
Finasteride works by reducing levels of DHT, the hormone linked to follicle shrinkage in androgenetic alopecia. This helps slow or stop hair loss—but it does not directly stimulate new growth.
Red light therapy fills that gap by:
Together, they create a more complete approach: finasteride helps preserve what you have, while red light therapy helps improve what grows back.
Hair loss treatment is a long-term commitment. While finasteride is taken daily, red light therapy provides a drug-free way to support follicle health over months and years—without adding systemic medications.
This combination often leads to:
Not all red light therapy devices are created equal—especially when used alongside a daily medication like finasteride. Comfort, consistency, and scalp coverage matter.
The GroWell cap delivers even light distribution across the scalp, ensuring consistent follicle stimulation—not spot treatment.
GroWell is FDA-cleared and completely non-invasive, making it a safe and effective complement to prescription treatments like finasteride.
Finasteride works best when patients stick with their regimen. GroWell’s lightweight, soft, wearable design makes red light therapy easy to incorporate into daily life—helping users stay consistent without discomfort.
GroWell’s removable light panel allows users to place the technology into most other hats, enabling discreet use and making long-term adherence far more realistic than bulky helmet-style devices.
“Finasteride helps slow hair loss by addressing DHT, but it doesn’t directly stimulate follicles to grow stronger hair,” said Dr. Samer Muala, a board-certified physician and founder of HimAndHair.com. “Red light therapy supports circulation, cellular energy, and follicle activity. When patients combine the two consistently, we often see improved density and better overall hair quality compared to medication alone.”
Dr. Muala also notes that red light therapy has been shown to improve results for other hair loss treatments, including minoxidil, PRP and even hair transplants – both pre- and post-procedure.
Finasteride plays an important role in many hair loss treatment plans—but pairing it with red light therapy helps address the full lifecycle of the hair follicle.
Together, finasteride and the GroWell Cap offer:
For individuals serious about long-term results, this combination provides a balanced, science-backed approach—without adding unnecessary complexity.
Yes. Red light therapy is non-invasive and works through a different mechanism than finasteride, making them highly compatible.
No. Red light therapy complements finasteride but does not replace its hormonal effects. Together, they provide a more comprehensive strategy.
Red light therapy can be started at any time and is often added to improve regrowth and hair quality.
Most users benefit from consistent use several times per week or every other day, depending on provider guidance.
Yes. FDA-cleared devices like GroWell are designed for ongoing, long-term use without drugs or downtime.
Red light therapy may help stimulate follicles and improve hair thickness, especially when consistency is maintained over time.
