The hair loss market today is huge! How do you choose the right products? How do you know which companies to trust? It can be a lot to take in, but we’ve done the research and we’ll reveal the top five trustable effective laser caps for hair loss in 2021.

All About LLLT: What is a Laser Cap?

Laser caps are a medical device designed for men and women wanting to improve the overall health of their hair. Whether you’re looking to regrow your thin or balding scalp, or you’re just wanting to strengthen and thicken your existing hair follicles you have left. Lucky for you, laser caps do both!

These devices use low-level laser therapy (LLLT) to naturally stimulate your hair follicles and encourage new hair growth. This is done through increased blood flow to the hair follicles and by reducing inflammation on your scalp. This allows the hair follicles to be more easily stimulated and encourages stronger hair growth.

Low-level laser therapy (LLLT) is a popular technology that’s gaining approval from several medical professionals and scientists all over the world for its success at treating hair loss. Not only is low-level laser therapy convenient and safe, but it actually works to treat hair loss for both men and women!

Do Laser Caps for Hair Loss Work?

The answer is YES! Many doctors are prescribing laser caps and noticing encouraging results in patients. In the course of various studies, LLLT helped slow down and stop hair loss in 85% of patients undergoing the treatment. Patients also saw new hair growth in 55% of these cases.

When compared to hair transplants, laser caps are extremely cheaper and you don’t have to undergo the needle to get your hair back. Not to mention laser caps are non-invasive, pain-free, and don’t come with the health risks of a hair transplant. According to the National Library of Medicine, some doctors and dermatologists are prescribing laser caps for post-hair transplant surgery patients to help speed up the healing process and boost earlier growth of the hair grafts.

** LLLT does not work in cases where baldness has occurred for many years and hair follicles are unresponsive. LLLT only works on active hair follicles.

Laser Cap for Hair Loss

Laser caps have worked their way into hair loss devices designed for at-home use. One benefit of laser caps is that they can be combined with other hair treatments like DHT blocking vitamins, Minoxidil, etc. They can also be used alone with no other treatments.

Laser cap benefits:

  • Prevents further hair loss
  • Stimulates hair growth
  • Increases hair strength, thickness, and overall hair health
  • Convenient at-home use
  • Unisex
  • Non-invasive
  • FDA-Cleared

How We Chose the Top 4 Laser Caps for 2021

All products in the hair growth industry must have FDA clearance before they can be sold on the market. They are in charge of clearing products that have gone through vast testing and research to prove these products are efficient and safe for human use. This clearance is confirmation that these medical devices are both safe and effective to use. All companies providing laser caps should be FDA-cleared to ensure that their laser emission is safe to use.

Many laser cap and hair growth companies use both low-level lasers and light-emitting diodes (LEDs) in their hair growth caps. What many customers aren’t aware of, is that light-emitting diodes don’t produce the same stimulation of hair growth as medical-grade lasers. To create enhanced cell function, light energy needs to be below a specific energy threshold and within a specific wavelength. LEDs are typically less effective because they’re relatively low-powered and don’t fit among the specific threshold and wavelength it takes to create this stimulation.

The top five laser caps we recommend are all FDA-cleared. We also recommend purchasing a laser cap that uses medical-grade laser diodes vs. LED lights. We’re %100 confident in our top choices.
