Do you know that an average person sheds between 50 to 100 hairs per day, and the lost hairs are often replaced with new growth? While this is completely normal, the hairs are not replaced in some people, thereby leading to a condition known as hair loss. Hair loss is exhausting, defeating, and can take a toll on your self-esteem. However, it doesn’t have to be a life sentence!
One of the possible treatments for hair loss is the use of a laser cap for hair growth. But do laser caps really work for hair growth and restoration? In this post, we uncover the technology behind this treatment option to help answer this question and determine if it might help to restore your hair.
What Is Laser Cap Therapy?
If you’re experiencing excessive hair loss, the chances are that you’ll be looking for a more serious treatment option after trying several over-the-counter treatments and found them lacking. Laser cap therapy is a hair loss treatment option that uses low-level laser light to stimulate the hair follicles and scalp to grow new hair. Studies have found this treatment option to be safe and effective in helping the scalp grow new hair and prevent hair thinning.
Laser Cap Therapy: The Science Behind It
The low-level laser light therapy (LLLT), also known as soft laser therapy, low-intensity light therapy, photobiomodulation, and cold laser therapy used in laser caps, was discovered by Dr. Endre Mester in the 1960s. This therapy applies light-emitting diodes (LEDs) or low-level lasers to the surface of the body.
While conducting a series of tests to detect if laser light causes cancer in animals, Dr. Mester applied LLLT technology on a shaved portion of the mice’s skin. Mester found that the therapy helped the mice to grow new hair instead of causing cancer. This test led to the creation of the safe and effective method used today to grow hair on humans.
The science behind LLLT used in Laser caps is that the light emitted from the caps penetrates the scalp and is absorbed by the cells to stimulate their protein synthesis and metabolism. The emitted light is in the infrared or red light range. As the light is absorbed, it invigorates cells by promoting blood circulation as well as nutrient and oxygen transport to the hair follicles. It can also increase adenosine triphosphate (ATP) production in hair follicle cells to promote metabolism and hair growth.
Do Laser Caps Really Work?
A 2018 study published in the Indian Journal Of Dermatology, Venereology, and Leprology associated LLLT with image satisfaction and improved outcomes in androgenetic alopecia patients. Similarly, a 2019 study in Lasers in Medical Science discovered that laser helmet therapy covered bald patches and increased hair thickness in patients with androgenetic alopecia.
Although the International Society of Hair Restoration Surgery highlights the need for more work in laser cap studies, indicating short duration and small cohort size as its limiting factors. Many doctors are now recommending the use of laser caps and seeing positive results in some patients.
Benefits of Laser Cap Therapy
The use of a laser cap for hair growth has been proven to be a safe and effective treatment option for age and genetic-induced hair loss. Moreover, it is very easy to use, has no known side effects, and is suitable for home use.
While you can use laser cap therapy as a standalone treatment for hair loss, you can combine it with other medical and surgical hair loss treatment procedures. Experts believe that combining it with other treatment options like platelet-rich plasma (PRP), micro-needling, exosomal injections, finasteride, Minoxidil, and hair transplant surgeries, can yield faster positive results.
The major benefits of wearing a laser cap for hair growth include:
- It is non-invasive and completely painless
- The therapy is not time-consuming. You can wear the cap for a few minutes, a few days a week.
- Its ability to stimulate the scalp and hair follicles to promote thicker hair growth has been clinically proven.
- It is FDA-approved.
- You can combine the therapy with other hair loss treatment options.
- It has no side effects.
- The cap is easy to use. It is suitable for home use and works for most patients.
- It can help reduce further hair loss.
- It increases hair density and strength.
What Other Ailments Can Low-Level Laser Therapy Treat?
According to Healthline, low-level laser therapy is used for decades to treat the following ailments safely:
- Side effects of cancer therapy
- Athletic performance
- Brain disorders
- Autoimmune diseases
- Tissues regeneration
- Promote wound healing
Therefore, you should not be afraid to use this technology for your hair loss treatment.
Who Is The Perfect Candidate for Laser For Laser Hair Therapy?
Does It Work for Everyone?
Generally, LLLT is meant for both men and women with all hair lengths that are experiencing or noticing hair thinning. That means that they’re probably in the early stages of hair loss. The outcome of laser cap therapy for baldness varies from a patient to another, depending on their hair cells’ health quality and hair loss type. However, the treatment is known to be efficient in people who are in the early stages of hair loss.
The therapy is effective for androgenetic alopecia patients. It can promote hair growth in females with frontal patterns of hair loss, Ludwig (Savin) I-4, II-1, II-2 classifications, or Fitzpatrick Skin Types I to IV, and males with Norwood Hamilton classifications of IIa to V, and Fitzpatrick Skin Types I to IV.
If you want to prevent hair loss or regrow your hair, you might consider using a laser cap for hair growth as a suitable treatment option. However, you should talk to your dermatologist to diagnose the type and level of hair loss you’re experiencing and recommend the best course of treatment for you.
Laser cap therapy is an effective treatment for hair loss. However, the results require consistency and patience as you need to wear the cap for several weeks before seeing a satisfactory result. Keep in mind that the earlier you begin your hair loss treatment, the higher your chances of avoiding irreversible damage.
