Hair light therapy: role, effectiveness and limitations

What is hair light therapy?

Hair light therapy is a non-invasive medical technique that uses cold light, typically light-emitting diodes (LEDs), to stimulate the scalp and promote healthy hair. Recognized in the field of hair medicine, it is part of a gentle and complementary approach to treatments against hair loss.

This process is based on the principle of photobiomodulation: light energy penetrates into the tissues of the scalp and acts at the cellular level. It helps to improve blood microcirculation, stimulate hair follicles and reduce local inflammation.

The mechanisms of action of light therapy

The light emitted by LEDs acts at a specific wavelength, generally between 630 and 680 nm for red light, and around 800 to 900 nm for near infrared. These frequencies are capable of stimulating the mitochondrial activity of cells, which increases the production of ATP, a source of cellular energy.

Applied to the scalp, this stimulation results in several beneficial effects:

• Improvement of vascularization : the blood supply is strengthened, which favors the nutrition of the follicles.
• Stimulation of hair growth : the hair bulbs are reactivated, thus delaying the miniaturization of the hair.
• Anti-inflammatory effect : light reduces scalp irritation and helps to reduce certain sensitivities.
• Regulatory action : it helps to stabilize the hair cycle, reducing reactive or progressive hair loss.

Main indications

Hair light therapy is aimed at different patient profiles. It can be proposed:

- For prevention, in people who observe a slight to moderate loss of hair density.
- In addition to medical treatments such as minoxidil or hair mesotherapy.
- After a hair transplant, in order to accelerate healing and stimulate regrowth.
- In patients suffering from beginning androgenetic alopecia or telogenic effluvium.

Course and pace of the sessions

A hair light therapy session generally lasts between 15 and 30 minutes. The patient is seated comfortably, and a helmet or LED device is positioned on the scalp. The treatment is painless and does not require anesthesia.

To achieve visible results, consistency is essential. The recommended protocols are based on several weekly sessions at the beginning, often 2 to 3 per week for three months, then an interview with 1 session every 2 to 4 weeks. Personalized medical follow-up is crucial to adapt the pace according to individual needs and response.

Expected results

The effects of hair light therapy occur gradually. Patients generally notice:

• A decrease in hair loss after a few weeks.
• A healthier, less irritated scalp.
• An improvement in the density and quality of the hair after several months.

It is important to note that the results vary according to the type of alopecia, age, medical history, and combination with other treatments.

Limits and contraindications

Although hair light therapy is a promising approach, it has some limitations:

- It does not allow hair to grow back on a scalp completely devoid of follicles.
- Its effectiveness is lower in advanced stages of baldness.
- It requires patience and good adherence to the protocol, because the results appear over several months.

Moreover, it is not recommended for patients suffering from certain photosensitive pathologies or following drug treatments that make the skin sensitive to light.
