LOW LEVEL LASER TREATMENT

WEB 4 MAR 1

Recently, I’ve noticed several friends on social media complaining about hair loss and the onset of baldness. Many have started using hair growth hats, sparking curiosity about the differences between various brands and models, including those with LLLT (Low Level Laser Therapy) and LED technologies. Questions arise about the effectiveness of these hair growth hats, which are used for just a few minutes each day. Do they really work? Can they also help with hair loss? Today, I will explain this in detail.

LLLT, standing for Low Level Laser Therapy, is a laser with low-frequency waves, having a wavelength range between 650-680 nm. This produces red light that is visible to the naked eye. When this low-frequency laser is projected onto the scalp, it leads to the absorption of energy and stimulates various cells to function more effectively.

LLLT (Low Level Laser Therapy) enhances the health of hair follicle cells and improves blood circulation in the scalp. This leads to an increase in nutrient supply to the hair, promoting the growth of new hair, reducing hair fall, and resulting in thicker and healthier hair.

In addition to benefiting hair growth, LLLT (Low Level Laser Therapy) also aids in wound healing on the scalp and reduces various inflammatory conditions. This makes it particularly beneficial for patients who have recently undergone hair transplantation. LLLT can improve the healing process, result in faster recovery of surgical sites, and promote the growth of stronger new hair while decreasing the risk of hair loss.

LED stands for Light-Emitting Diode, which is essentially a standard diode that emits light. The principle behind LED is to provide illumination. The light produced by LEDs is cool or has very minimal heat, allowing it to be touched with bare hands. Although LEDs do emit light waves, these waves are not capable of stimulating hair follicles.

The clear difference between LLLT (Low Level Laser Therapy) and LED is basically about efficacy (with a bit of humor: ‘usable’ vs. ‘not really usable’). As previously mentioned, LLLT emits low-frequency, continuous waves that stimulate hair follicles. In contrast, while LED might emit similar frequencies, these are intermittent and do not continuously stimulate the hair roots and thus have no effect on hair stimulation. However, one advantage of LED over LLLT is its significantly lower cost.

Benefits of LLLT (Low Level Laser Therapy) Laser Treatment

  1. Safe and Side-effect Free: LLLT is known for its safety, posing no significant side effects.
  2. Improves Hair Follicle Health: The therapy enhances the functioning of hair follicles, leading to the growth of higher quality new hair.
  3. Thickens and Darkens Hair: It contributes to thicker hair and improves its overall appearance, making it look denser and darker.
  4. Reduces Hair Loss: LLLT effectively reduces hair breakage and shedding.
  5. Decreases Scalp Inflammation: The therapy helps in reducing scalp inflammation.
  6. Aids in Scalp Wound Healing: Particularly beneficial for individuals who have recently undergone hair transplantation, as it facilitates the healing process on the scalp.

Limitations of LLLT (Low Level Laser Therapy) Laser Treatment

  1. LLLT is not suitable for individuals who are completely bald or have no remaining hair follicles.
  2. Although LLLT can be performed frequently, overuse may lead to a dry scalp.
  3. The treatment results from LLLT are slower compared to other methods, requiring patient discipline, patience, and consistency.

Summary

LLLT (Low Level Laser Therapy) operates by emitting low-frequency, continuous waves that stimulate hair follicles, enhancing their efficiency. This results in new hair growth that is of higher quality, thicker, and darker. Additionally, LLLT aids in healing scalp wounds and effectively reduces hair loss. On the other hand, LED is merely a light-emitting diode that provides illumination without playing any role in stimulating hair follicles. LLLT is safe and side-effect free, but its results are slower compared to other hair restoration methods and it is not suitable for individuals without any remaining hair follicles.
