Red Light Therapy for Hair Regeneration.

Red light therapy uses low-level laser or LED light to stimulate hair follicles at the cellular level. Also known as Low-Level Laser Therapy (LLLT) or photobiomodulation, it applies specific wavelengths of red and near-infrared light that support the follicle's natural growth cycle — helping strengthen and thicken hair over time, without pain or downtime.

Red light therapy for hair at PROGEN

The science

What is red light therapy?

Red light therapy — also known as Low-Level Laser Therapy (LLLT) or photobiomodulation — uses specific wavelengths of red and near-infrared light to stimulate hair follicles at the cellular level. The light energy supports the follicle's natural growth cycle, helping to strengthen and thicken hair over time.

It's non-invasive, painless, and has an excellent safety profile, with no downtime. Red light therapy works best as part of a combined protocol — frequently paired with microfocused ultrasound or PRP therapy — and with consistent treatment.

MFU vs. PRP vs. red light — which is right for you?

Three non-surgical paths to healthier hair — often combined in one regenerative plan.

✦ Flagship

Microfocused Ultrasound

How it worksFocused ultrasound energy reaches the scalp layers where follicles live, stimulating dormant follicles to regenerate.
Needles or surgeryNone — non-invasive, no needles for the core treatment.
Typical course3–6 sessions, about 60 minutes each.
DowntimeNone.
Role in your planThe flagship PROGEN™ treatment for waking dormant follicles.
Microfocused ultrasound hair restoration
Often combined

PRP Therapy

How it worksGrowth factors concentrated from your own blood are delivered to the scalp to stimulate regeneration.
Needles or surgeryA small blood sample; platelets are then delivered to the scalp.
Typical courseA series of sessions, followed by periodic maintenance.
DowntimeReviewed at your consultation.
Role in your planOften combined with MFU for enhanced results.

Red Light Therapy

How it worksLow-level laser or LED light (photobiomodulation) stimulates follicle cells at the cellular level.
Needles or surgeryNone — non-invasive and painless.
Typical courseConsistent treatment as part of a combined protocol.
DowntimeNone — no recovery period.
Role in your planSupports the healing rhythm between MFU sessions.
