How Laser Therapy Can Regrow Hair


While it might sound like it’s straight out of a sci-fi movie, low-level laser therapy is a clinically proven hair restoration treatment. If you are starting to notice hair thinning or have been balding for years, low-level laser therapy or LLLT can help you grow back your hair in just 4-6 months.

How does LLLT work?

The science behind laser therapy dates back to the ’60s. A research team tested how laser therapy affected cancer when they noticed the mice they had shaved for the testing were growing back their hair rapidly. This discovery leads to several more studies, and, eventually, low-level laser therapy hit the market as a hair loss solution.

LLLT works in five ways to restore hair loss at a cellular level:

  • Increases Blood Flow

LLLT supports hair growth through the process of photodissociation, which helps nitric oxide widen blood vessels which enhances blood flow circulation.

  • Increases Oxygen Delivery

LLLT separates nitric oxide and cytochrome c oxidase, which then bind together to move oxygen more efficiently, creating enhanced oxygen delivery to energize hair follicles.

  • Reduces the production of DHT

DHT is a well-known hair loss hormone caused by the conversion of testosterone into dihydrotestosterone (DHT). While LLLT does not directly block DHT, it does inhibit the conversion of testosterone into DHT.

  • Encourages Stem Cell Growth

LLLT activates shock proteins that boost stem cells in your hair follicles, supporting hair growth from your cells innermost layers.

  • Creates Beneficial Inflammation

Some inflammation is helpful for your body and, in smaller doses, can actually help encourage new hair growth without any harmful side effects.

Can You Use LLLT With Other Hair Loss Methods?

LLLT can be used in conjunction with other hair loss treatments like minoxidil, hair growth vitamins, and is even recommended after hair transplants. Since LLLT is safe and non-invasive, it works well with other hair growth remedies to increase results.

Can LLLT Be Used At Home?

LLLT can be used in a doctor’s office or in the comfort of your own home. The lasers are typically housed in a laser cap and then you simply wear the cap a few times per week to stimulate hair growth. Not all laser caps are created equal however, so it’s best to find a laser cap that has been FDA cleared for safety and effectiveness.

How Long Does It Take To See Results From Laser Therapy?

You can typically expect results in about 6 months, however sometimes it might take longer depending on your hair loss. You can also speed up your results by combining LLLT with other hair growth methods.

So, Does LLLT Really Grow Back Your Hair?

Yes, LLLT is an effective hair growth method that works for both men and women. Studies have found that LLLT significantly improves hair growth with a visible 39% improvement in just a few months of use.

At the end of the day, hair loss is hard to deal with and it can wreak havoc on your confidence. However, the good news is hair growth therapies like LLLT can help you improve your scalp health and regrow your hair in just a few months.
