What Is A Laser Cap?

Low-level laser therapy (LLLT) also known as cold laser therapy or red light therapy illuminates photons into the scalp tissues. These photons get absorbed by the weak cells to promote hair growth. low-level laser therapy is a popular less invasive procedure that is safe and widely accepted. The red light from Laser hair growth devices can rejuvenate the thinning hair follicles and prolong the growth cycle called anagen by increasing the blood circulation and it can further stimulate hair growth factors.

The red light energy increases ATP production, this leads to release in nitric oxide and energy in the hair follicles. This process improves oxygen and nutrient delivery and stimulates the metabolic process. All of this counters the negative effects of Dihydrotestosterone[3] (DHT), the main cause of hair loss.

The wavelength of lasers and the photon density may vary depending on the laser hair growth device. However, the diodes in low-level laser therapy emit infrared radiation or red light that ranges between 630-670 nm. This low-level laser therapy generates light and heat that stimulates the activity of hair follicles. This process is done via mitochondria with photochemical and photosynthesis-type reactions. 

Does Laser Therapy Really Work?

Low-level Laser therapy functions with medical-grade lasers that deliver safe and low-levels of red light to the scalp. Think of it like watering plants. Similar to watering plants the hair follicles absorb light energy. As the light is absorbed, microcirculation increases the blood circulation and nutrients to the hair follicle. low-level laser therapy stimulates cellular activity to the follicles to reduce hair loss and stimulate hair regeneration and helps hair regrowth.

A 2013 study[4] in 41 males of age between 18- 48 with androgenetic alopecia reported that laser hair growth treatment at 655 nm improved the hair counts. It also showed an improvement of a 39 percent increase in hair growth in androgenetic alopecia.

Along with new hair growth, laser growth devices can prolong the growth phase (anagen) in the hair cycle. Furthermore, they also stimulate the shedding (catagen phase) and resting (telogen phase) to speed up the process resulting in the shift of these cycles into the growth phase producing anagen hair. The increased blood flow due to the light from laser hair growth devices can make your hair healthier and appear vibrant. 

Coming to the safety of red light, a 2014 study reported[5] it to be safe and effective in both men and women for hair growth. The main mechanism observed was in the bulge of hair follicles where stimulation of epidermal stem cells took place to make a shift in follicles to anagen phase. 

Laser hair growth devices are clinically proven to stimulate hair regrowth, reducing thinning hair, increasing hair density and strength of existing hair. It is non-invasive and painless, with zero side effects. It can be used by both men and women for all kinds of hair lengths. And can be used in the comfort of your home with the laser hair growth device that best suits your usage.

How Does LLLT Therapy Work For Hair Loss?

Low-level therapeutic laser light therapy improves blood supply to the scalp and hair roots to promote hair regrowth. Laser devices for hair growth are a widely accepted method of treatment for thinning hair. Laser light also decreases shedding. Laser devices further block the Dihydrotestosterone which is the main cause of hair loss. 

Laser light hair growth caps activate the keratin protein that further promotes stem cell growth. These laser light caps improve the thickness and make the hair follicles strong. This results in fuller, thicker and healthier hair.

Are Laser Hair Growth Devices Safe?

Low-level laser therapy is not only used for hair growth but is also used for various medical conditions like nerve regeneration, wound healing, joint pain, prevention of mucositis and in treating mucositis and stroke recovery.Low-level laser therapy has demonstrated very few adverse effects when used to treat diverse medical conditions for 50 years in different parts of the body. 

Coming to the adverse effects[5] caused due to low-level laser therapy for hair growth in humans is the temporary onset of telogen effluvium ( increased hair shedding) in the first 1-2 months after using lasers. However, it will disappear after continued usage. Some other effects are dysplastic or malignant lesions on the scalp which are possibly accelerated to grow by proliferative effects of low-level laser therapy. Overall, low-level laser therapy is safe and effective in both males and females.

How to Use Laser Cap to Get The Best Result?

LLLT is most effective when combined with other treatment options[7] such as minoxidil and finasteride. LLLT may have synergistic effects when combined with them to enhance hair growth. However, LLLT inhibits potential effects in treating both male and female pattern baldness either as monotherapy or when accompanied with other treatments. Laser hair growth caps can also be combined with exosomal injections or a blend of hair regrowth medications such as Platelet-rich plasma (PRP) injections. They can also be worn on hair transplants. 

Precautions

Your scalp is a sensitive area. So, when you undergo laser cap treatment, you must follow some precautions to make sure that everything goes well, while also ensuring that you obtain optimum results. So, here are a few things you need to keep in mind when taking laser cap treatment for hair growth.

  • Try to avoid taking hot showers. The extra heat generated from the hot water may act against or irritate the treated regions. Try taking normal showers for a few days after the treatment.
  • Also, try not to do extreme workouts. Because, when you do so, it raises your body temperature, which may again irritate your treated areas. 
  • Additionally, do not apply harsh skin or hair products for at least one week after the laser cap treatment. The chemicals may disrupt the scalp, which is a counterproductive action. 
  • Finally, try to spend less time out in the sky, especially in the afternoons. You may not be able to avoid the sun completely, but try to do it as much as you can. 

Frequently Asked Questions
