Photobiomodulation to prevent hair loss
Hair loss is a universal concern that affects men and women at different stages of their lives. It can be due to genetic, hormonal, environmental or stress-related factors.
Fortunately, photobiomodulation (PBM) offers an effective, non-invasive preventative solution to slow hair loss and maintain a healthy scalp. This technology uses light wavelengths to act directly on the hair follicles, stabilising their activity and strengthening their structure.
Understanding the causes of hair loss
Before diving into the benefits of PBM, it is essential to understand the main causes of hair loss:
1. Androgenetic alopecia: Linked to genetic and hormonal factors, this condition is responsible for the majority of cases of hair loss.
2. Stress and fatigue: These factors disrupt the hair cycle, leading to temporary but often significant hair loss.
3. Nutritional deficiencies: A lack of essential nutrients such as iron, zinc or B vitamins can weaken the follicles.
4. Environmental factors: Pollution, UV rays and aggressive chemicals can make hair more fragile.
PBM acts as a protective barrier, preventing these factors from worsening while stimulating natural regeneration processes.
Stabilisation of hair follicles
PBM plays a central role in preventing hair loss by strengthening the health of hair follicles. When exposed to red or infrared light, the follicles produce more ATP, improving their metabolic activity. This stimulation helps to prolong the anagen phase, when hair actively grows, while delaying the telogen phase, when hair falls out.
In addition, PBM reduces inflammation around the follicles, a condition often linked to weakening and hair loss. By re-establishing a healthy environment, this technology prepares the ground for eventual regrowth while limiting existing loss.
Anti-inflammatory role and protection against oxidative stress
Chronic inflammation and oxidative stress are two of the main enemies of hair health. PBM acts as a powerful inflammatory modulator, calming excessive scalp reactions. It also stimulates the production of natural antioxidants that neutralise the free radicals responsible for premature ageing of the follicles.
By combining these effects, PBM preserves the structure of hair follicles and improves their resilience in the face of external aggression. This action is particularly important for people living in polluted urban environments or under constant stress.
Optimising the capillary cycle
PBM acts directly on the hair cycle, promoting a harmonious transition between its different phases. By prolonging the anagen phase and shortening the catagen (resting) phase, it maximises the time during which hair is actively growing. This regulation helps to maintain optimum hair density and prevent episodes of excessive hair loss.
This balancing role is particularly useful for people suffering from seasonal or temporary hair loss linked to hormonal disturbances or lifestyle changes.
Integration with complementary strategies
For optimum results, PBM can be combined with other preventive solutions, such as :
Appropriate hair care: The use of nutrient-enriched shampoos and serums supports the action of PBM.
Balanced nutrition: A diet rich in proteins, vitamins and minerals boosts the effects of the treatment.
Stress management: Incorporating activities such as yoga or meditation can reduce the impact of stress on hair loss.
This holistic approach maximises the chances of preserving a healthy, full head of hair.
Conclusion: an effective preventive barrier
Photobiomodulation offers a powerful preventative solution to hair loss. By stabilising follicles, reducing inflammation and protecting the scalp from oxidative stress, it plays a key role in preserving hair density. Combined with complementary treatments, it not only helps prevent hair loss, but also improves the overall health of the hair. This technology represents a major advance for all those who want to act upstream and keep their hair shiny and healthy.
