The technology

Light that the skin uses

Photobiomodulation relies on precise wavelengths, studied in clinical research. No UV, no heat, no recovery period — 10 minutes a day, at home.

Growth begins at the cell.

Red and infrared light. 10 minutes a day. No pills.

Protect your hair

What does the light do

Activates hair follicles

660 nm penetrates directly into the root and activates the mitochondria.

Improves circulation

More oxygen and nutrients to the scalp.

Extends growth

Hair grows longer before falling out. Thicker and healthier.

Works deep

850 nm reaches the dermal papilla—where the hair begins.

Without hormonal intervention

A light-based routine without added medication. Follow the manual and contraindications.

10 minutes a day

At home. Whenever you want. No visits, no rituals.

Frequently Asked Questions

The LED cap uses a combination of 660 nm red light and 850 nm infrared light, directed straight to the scalp. This type of light therapy is used as a non-invasive approach to support the scalp and hair cycle with regular use.

With consistent use, this type of light therapy is most often associated with improved density, healthier-looking hair, and support for the natural growth cycle.

This type of therapy does not yield immediate results. Typically, regular use over several months is required to assess any real change.

Yes, the LED cap is suitable for both men and women who are looking for complementary care for thinning hair and reduced density.

Yes, this is one of the most common cases in which this type of light therapy is used. It is applied as a supplementary, non-invasive approach to hereditary hair thinning.

Yes, the cap is designed for targeted scalp care for hair with reduced density, thinning, and gradual hair loss.

No, the therapy is non-invasive and painless. When used correctly, it should not cause pain, and is most often perceived as a gentle and comfortable procedure

When used correctly, these types of devices are generally well tolerated. If your scalp is severely irritated, inflamed, or you have a specific dermatological condition, it is advisable to consult a specialist first.

The best approach is regular and consistent use according to the chosen regimen and timer setting. Consistency is one of the most important factors in this type of therapy.

Yes, LED therapy is often considered a supportive treatment for the scalp and hair, and there is evidence that this type of light therapy can support hair growth and density with regular use.

After a transplant, however, it is important to wait for the scalp to fully recover and to start using it only after consulting with the specialist who performed the procedure. This ensures that the approach is consistent with the individual's healing stage and the post-operative plan.
