It’s new technology, but can you benefit?
If you’re looking for ways to grow your hair, then you’ve likely seen some red light therapy products being promoted on social media. More red light therapy products are being reviewed and approved by the FDA every day, and thousands of studies have shown that red light therapy can indeed promote hair growth.
However, it’s still fairly new technology, and research is still being done on how exactly it all works. Let’s analyze how red light therapy targets your hair follicles to encourage hair growth and give you fuller-looking hair.
How Does Red Light Therapy Support Hair Growth?
Stimulates Hair Follicles
Red light therapy delivers specific wavelengths of light that are absorbed by mitochondria, also known as the “powerhouses” of your cells. This process helps increase the production of adenosine triphosphate (ATP), which is the molecule your cells use for energy. With this increase in cellular energy, hair follicles may function more efficiently to help slow hair loss and regrow thinning hair.
Increases Blood Circulation
Some research suggests that red light therapy may improve blood circulation in the scalp. Better circulation helps deliver oxygen and nutrients to hair follicles, creating an environment that supports healthier-looking hair.
Extends the Hair Growth Phase
One 2021 study showed that red light therapy can help delay hair shedding by keeping hair follicles in the growth (anagen) phase for longer. As a result, your follicles may spend more time actively producing hair before entering the shedding (exogen) phase. This can contribute to thicker, fuller-looking hair over time.
What Results Can You Expect?
It’s important to understand that hair growth of any kind takes time. Furthermore, not everyone will see the same results.
The results you see can vary based on the individual and the cause of their hair loss. According to a dermatologist and Mohs surgeon at Shafer Clinic NYC, red light therapy is recommended for anyone experiencing mild to moderate hair thinning.
Most users see gradual improvements after several weeks or months of consistent use. Over 3-6 months, you may notice reduced hair shedding and increased hair thickness in some spots.
Factors such as genetics, aging, hormonal changes, stress, and certain medical conditions can affect what results you see. However, with a regular red light therapy schedule, you’re more likely to see a difference in your hair.
Who Can Benefit?
People experiencing mild to moderate hair thinning are more likely to see some hair growth success with red light therapy. Men and women with hereditary pattern hair loss can also benefit from it.
Of course, anyone with sudden or severe hair loss should consult with their doctor before using red light therapy. If you’re unsure of which products to use or how long to use them for, then your doctor will help you make the healthiest decision for your hair.
Tips for Getting the Best Results
Keep in mind that not every red light therapy on the market will be effective for promoting hair growth. According to the American Hair Loss Association®, there are certain criteria to consider when choosing a red light therapy product for your hair. Having FDA clearance and a proven LLLT (low-level light therapy) technology rating is key.
Perhaps the most crucial tip to keep in mind is to use red light therapy consistently, as the effects stop if you stop using it. Follow the manufacturer’s recommendations on how long and how often you should use your red light therapy device to maximize your hair growth potential.
Red light therapy works best when your scalp is clean and free of excess oil, dirt, or product buildup. Maintaining a proper haircare routine will ensure that the light reaches your scalp and hair follicles more effectively, thus leading to more consistent growth. A healthy, protein-packed diet with key nutrients (like Vitamin D and Vitamin C) can help too.
Although red light therapy isn’t an overnight solution for hair loss, growing research suggests that it can be a valuable addition to your haircare routine. With regular use and realistic expectations, it may just give you a healthier and fuller-looking head of hair.
