From the Guidelines
Red light therapy is best suited for patients with alopecia areata, as evidenced by studies showing significant hair regrowth in treated patches compared to untreated ones 1.
Patient Selection
The ideal candidates for red light therapy include those with:
- Androgenetic alopecia (male or female pattern baldness)
- Alopecia areata
- Chemotherapy-induced hair loss
- Thinning hair due to aging, hormonal changes, or stress
Mechanism of Action
Red light therapy works by stimulating cellular energy production in hair follicles using low-level light wavelengths (typically 630-670 nanometers), increasing blood circulation to the scalp, and reducing inflammation.
Treatment Protocol
For optimal results, patients should undergo treatments:
- 3-5 times weekly
- For 10-20 minutes per session
- Continuing for at least 3-6 months
Devices and Administration
Most devices for home use include LED panels, helmets, or combs, with professional treatments available at dermatology clinics.
Safety and Contraindications
Red light therapy is non-invasive with minimal side effects, making it suitable for most people, though pregnant women and those with photosensitivity conditions should consult a healthcare provider first.
Combination Therapy
This therapy can be used alone or as a complementary treatment alongside minoxidil, finasteride, or other hair loss interventions for enhanced results.
From the Research
Patient Types Suitable for Red Light Therapy
- Androgenetic alopecia patients: Red light therapy has been shown to be a promising treatment option for patients with androgenetic alopecia, with significant increases in hair density observed after treatment 2, 3.
- Telogen effluvium patients: While there is limited data on the use of red light therapy for telogen effluvium, some studies suggest that it may be a viable treatment option, particularly when combined with other treatments such as oral minoxidil or topical trichological treatments 4, 5.
- Alopecia areata patients: There is limited data on the use of red light therapy for alopecia areata, but some studies suggest that it may be a potential treatment option, particularly when combined with other treatments 2, 6.
Hair Concerns Suitable for Red Light Therapy
- Hair thinning: Red light therapy has been shown to increase hair density and thickness, making it a potential treatment option for patients with hair thinning 2, 3.
- Hair loss: Red light therapy has been shown to promote hair growth and reduce hair loss, making it a potential treatment option for patients with hair loss 2, 3.
- Scalp health: Red light therapy has been shown to improve scalp health, reducing inflammation and promoting a healthy environment for hair growth 3.
