What Happens to Hair Treated with Laser Therapy?

Laser therapy for hair growth, also known as photobiomodulation, low-level laser therapy (LLLT) or red light therapy, is a non-invasive treatment approach used to stimulate hair follicles and promote hair regrowth in individuals experiencing hair loss or thinning. When hair is treated with laser therapy, several physiological effects occur.

Timeline of Miniaturized Hair Treated with Laser Therapy

  1. Increased Blood Flow to the Scalp: Laser therapy may stimulate blood circulation in the scalp. This improved blood flow brings essential nutrients, oxygen, and growth factors to the hair follicles, promoting their health and function.

  2. Activation of Cellular Metabolism: The light energy from lasers penetrates the scalp and is absorbed by the mitochondria within the cells of the hair follicles. This absorption of light energy can enhance cellular metabolism, leading to increased energy production and improved cellular function.

  3. Stimulation of Hair Follicles: Laser therapy can activate dormant or weakened hair follicles, prompting them to enter the anagen (growth) phase of the hair cycle. This stimulation can lead to the production of thicker, healthier hair strands over time.

  4. Reduction of Inflammation: Laser therapy has been shown to have anti-inflammatory effects, which can be beneficial for individuals with inflammatory conditions affecting the scalp, such as alopecia areata or certain types of scalp dermatitis. By reducing inflammation, laser therapy may create a more favorable environment for hair growth.

  5. Prolongation of Anagen Phase: Laser therapy may prolong the duration of the anagen phase of the hair growth cycle. This can result in longer periods of active hair growth and contribute to increased hair density and coverage on the scalp.

  6. Reduction of Hair Loss: Laser therapy has been reported to reduce excessive shedding or hair loss by strengthening existing hair follicles and promoting the growth of new hair. This effect can help individuals maintain their current hair density and prevent further hair thinning.

Overall, laser therapy for hair growth can have beneficial effects on the health and appearance of the hair by stimulating hair follicles, improving scalp health, and promoting hair regrowth. Individual responses to laser therapy may vary, and consistent use over an extended period is often necessary to achieve noticeable results.
