Photobiomodulation and hair regrowth in men and women

Hair loss affects men and women differently, both in its causes and its psychological impact. Photobiomodulation (PBM), thanks to its natural and non-invasive mechanisms, adapts to these differences to offer a personalized solution. This page explores how PBM acts on male and female hair problems, while presenting its benefits in stimulating hair regrowth.

Differences between men and women in hair loss

2149541819

In men:

Hair loss is often linked to androgenetic alopecia, caused by the sensitivity of hair follicles to dihydrotestosterone (DHT). This type of hair loss manifests itself by a receding hairline and progressive baldness.

In women:

Hair loss is generally diffuse and linked to hormonal changes, such as pregnancy, menopause or thyroid disorders. The follicles are not irreversibly damaged, but their growth cycle is disrupted.

These differences influence how treatments must be adapted to be effective.

The benefits of photobiomodulation for men

In men, PBM acts directly on the follicles sensitized by DHT by stimulating their cellular activity. By improving blood microcirculation, it promotes the supply of essential nutrients and oxygen to weakened follicles.

Reduction of follicular inflammation: PBM limits the inflammatory reactions caused by DHT, creating a more favorable environment for hair growth.

Prolongation of the anagen phase: By stimulating the mitochondria of follicular cells, PBM extends the active growth phase, allowing hair to become thicker and stronger.

Prevention of the progression of baldness: Although PBM cannot regenerate completely inactive follicles, it slows down hair loss and preserves the areas still covered.

    The benefits of photobiomodulation for women

    In women, PBM offers an ideal solution to stabilize hair cycles disrupted by hormonal variations. By improving the biological conditions of the scalp, it promotes harmonious hair growth.

    Regulation of growth cycles: PBM helps restore a balanced hair cycle by stimulating follicles in the resting phase to enter the growth phase.

    Strengthening existing hair: Fine or fragile hair benefits from better cellular nutrition, improving its thickness and resistance.

    Prevention of diffuse hair loss: PBM acts as a protective barrier against the effects of environmental or stress factors, often responsible for diffuse hair loss.

      A gender-specific approach

      Although the mechanisms of action of PBM are the same, its application can be modulated to meet the specific needs of men and women:

      For men: A more targeted use on areas prone to baldness, such as the crown of the head and the hairline.

      For women: A more generalized application to treat the entire scalp, with an emphasis on thinning areas.

      This customization guarantees maximum effectiveness while respecting biological and hormonal differences.

      Combination with other treatments

      PBM can be combined with other approaches for optimal results:

      In men: In addition to treatments such as minoxidil or finasteride to slow the progression of alopecia.

      In women: In combination with nutrient-enriched hair care or hormonal treatments tailored to individual needs.

      This combined approach enhances the benefits of each treatment while providing a comprehensive and sustainable solution.

      Influence of hair care habits on results

      Hair care habits play a crucial role in the effectiveness of photobiomodulation treatments. Inadequate practices can limit the benefits of PBM, while an optimized routine can enhance them. Here are some things to consider:

      Choice of hair products: Choose shampoos and treatments without sulfates, parabens or silicones, which respect the natural balance of the scalp.

      Washing frequency: Adapt the frequency of washing to avoid drying out or weighing down the hair, depending on its nature.

      Scalp massage: Incorporate gentle massages to stimulate blood circulation and complement the effect of PBM.

      Protection against external aggressions: Limit exposure to UV rays, excessive heat (hair dryers, irons) and pollution, which weaken the follicles.

      By optimizing these habits, men and women can create an environment conducive to hair growth, while maximizing the benefits of photobiomodulation.
