Hair loss is a common concern for both men and women, often caused by genetics, stress, hormonal changes, or aging. While there are many treatment options, Terapia com luz vermelha (Rlt) has emerged as a safe, não invasivo, and clinically proven method to support hair regrowth.
This guide explains how red light therapy works for hair loss, its benefits, how to use it, and what results you can expect.
O que é terapia com luz vermelha?
Red light therapy uses low-level wavelengths of red and near-infrared light (typically 630–850nm) to stimulate natural healing processes in the body. Unlike UV light, it does not damage DNA or cause burns. Em vez de, it penetrates into the skin and scalp to energize cells and promote regeneration.
How Red Light Therapy Helps with Hair Loss
- Estimula os folículos capilares
- Red light penetrates into the scalp and triggers dormant follicles to re-enter the anagen (growth) phase.
- Aumenta a circulação sanguínea
- Enhances delivery of oxygen and nutrients to the scalp, improving follicle health.
- Boosts Cellular Energy (ATP)
- Light energy stimulates mitochondria in hair follicle cells, improving function and growth capacity.
- Reduces Scalp Inflammation
- Calms irritation, which is often linked to thinning hair or shedding.
Benefits of Red Light Therapy for Hair
- Encourages new hair growth in thinning areas
- Strengthens existing hair shafts
- Improves scalp health and circulation
