Red light therapy, or low-level light therapy (LLLT), consists of visible red light and invisible near-infrared light (NIR). It works by penetrating the skin and reaches each of your cells, promoting cellular metabolism and accelerating blood circulation.

Can red light therapy reverse grey hair?

red light therapy reverses grey hair

Promotes melanin production & blood circulation

According to recent research, red light therapy can reverse the signs of aging, givin g us a younger look. So it's no surprise that red light therapy is gaining popularity among people who want to slow the greying process and maintain their natural hair colors.

Red light therapy can help rectify greying process by stimulating the body's production of melanin, thereby reversing or preventing further greying of the hair. It also  increases blood circulation and oxygen flow to the roots of your hair follicles. This is significant because it allows for better delivery of nutrients and oxygen to your scalp, allowing your body to naturally create more melanin.

Improves cellular metabolism & hair quality

Furthermore, red light penetrates deep into the cells, activating certain enzymes that accelerate cellular metabolism. Red light also reduces inflammation and mends damaged cells. This replenishes your hair follicles with the nutrients they require to regrow healthy strands. Red light therapy, through these mechanisms, can also prevent additional damage and promote healthy new hair growth in its stead. Additionally, red light treatment is effective for eliminating dandruff and increasing scalp health.

Relieve pressure

Over stress can cause the greying of the hair by messing up your hormones. Red light therapy helps reverse grey hair by relieving your pressure through the promotion of metabolism and blood circulation.

Powerful as red light therapy is, it doesn’t reverse grey hair caused by aging. In fact, there is not a single device that can reverse grey hair by aging. Hair dye may help, but it’s just a temporary solution.

Other than red light therapy, what can I do to reverse grey hair?

Indeed, red light therapy is an ideal treatment to reverse grey hair. That being said, there are some other tips for you to reverse grey hair.


You can use laser therapy to eliminate grey hair. It also  penetrates the scalp to produce its effects. However, compared with red light therapy, which is a safe, affordable, and non-invasive treatment, laser poses a bigger threat to our health and, in most cases, very expensive. 

Hair dye

It is a common treatment to combat gray hair using hair dye. Men and women travel monthly to salons to get the proper hair coloring to cover up these gray hair strands on the head. When deciding to dye your hair, look for products that are designed to specifically cover gray hair. Permanent dye will better cover the roots of your hair and will dye them for a longer period of time.

When dying your hair, it is important to keep in mind that excessive dying can cause damage to your hair, which could potentially make the hair weaker and more brittle. Dying your hair can also get expensive.

Stop plucking the grey hair
