How LLLT Lasers Work to Treat Hair Loss

Hair loss can be a common issue among both men and women, and it can be a frustrating experience. There are many different treatments available for hair loss, including laser therapy. In this blog post, we will explore the use of a 650nm laser for hair loss and its effectiveness.

What is a 650nm laser?

A 650nm laser is a low-level laser therapy (LLLT) device that emits red light at a wavelength of 650nm. This wavelength is within the visible light spectrum and is often referred to as "cold" laser therapy, as it does not produce heat or damage the skin. The red light is absorbed by the hair follicles, which then stimulates cell activity and promotes hair growth.

How does laser therapy work for hair loss?

Laser therapy works by stimulating blood flow to the hair follicles, which provides more nutrients to the hair and encourages new growth. The red light from the laser also increases the production of ATP (adenosine triphosphate), which is essential for cell growth and repair. By increasing the amount of ATP in the hair follicles, the laser helps to accelerate the growth cycle of the hair.

The laser also helps to reduce inflammation and oxidative stress in the scalp, which can contribute to hair loss. By reducing inflammation, the laser promotes a healthy environment for hair growth, and by reducing oxidative stress, it helps to prevent damage to the hair follicles.

How effective is a 650nm laser for hair loss?

Several studies have shown that laser therapy can be effective in promoting hair growth and reducing hair loss. A 2013 study published in the Journal of Clinical and Aesthetic Dermatology found that a 650nm laser was effective in promoting hair growth in both men and women with androgenetic alopecia, which is a common form of hair loss.

Another study published in the Journal of Cosmetic and Laser Therapy in 2014 found that a 650nm laser was effective in increasing hair density and thickness in men with male pattern baldness.

While laser therapy is not a cure for hair loss, it can be an effective treatment option when used in conjunction with other therapies, such as topical medications or hair transplant surgery.

Conclusion

A 650nm laser can be an effective treatment option for hair loss, particularly for individuals with androgenetic alopecia or male pattern baldness. The laser works by stimulating blood flow to the hair follicles and increasing the production of ATP, which promotes hair growth and reduces inflammation and oxidative stress in the scalp. While laser therapy is not a cure for hair loss, it can be a useful tool in the treatment of this condition. If you are experiencing hair loss, speak with a healthcare professional to determine the best treatment options for your individual needs.
