You don’t need to be a beauty expert to know that at-home LED light therapy devices are having a moment. The term “red LED light therapy” has more than 70 million views on TikTok, and according to Grand View Research, it’s a market valued at more than $238 million. But whereas treating the skin on your face has been the primary focus of at-home LED light therapy devices in the past, brands like Laduora are bringing those same cell-stimulating and inflammation-fighting benefits to your scalp. The brand’s DUO device combines red LED light therapy with a targeted serum to help stimulate hair growth while also optimizing the health of the scalp for overall healthier hair. And though it’s a bit of an investment, the handheld device is currently on sale for 30% off when you use the code ‘MAMA’ at checkout, saving you nearly $100. Because the discount was created for Mother’s Day, you can shop the sale from April 26 through May 13, and keep reading for all of the details behind the patented at-home treatment.

The science behind the device

For a little bit of background on red LED light therapy, it’s a technology that was first developed by NASA to help plants grow in outer space as a food source for astronauts. That quickly led to studying LED light therapy’s effectiveness in the medical community (particularly, as it pertains to wound healing). And eventually, it began being used in dermatology to treat skin conditions before finally making its way to at-home devices.

About the Laduora DUO

Laduora’s DUO device offers a unique take on red LED light therapy, as it combines several different technologies with a topical product. First and foremost, you’re getting the red LED light therapy at a wavelength of 660nm, which has been shown to increase hair growth by prolonging the anagen phase (aka the growth phase). The thought behind red LED light therapy’s success for a fuller head of hair is that, much in the same way it works for the skin on your face, the light helps to stimulate hair follicles and reduce inflammation. Further assisting with increasing blood flow to the hair follicles is the addition of microcurrent technology, a scalp-massaging vibration, and therapeutic warmth. The DUO’s vibration and therapeutic warmth components also help to create a more relaxing treatment, while the latter can allow for deeper penetration of the skin care products you use immediately following your red LED light therapy session.


That therapeutic warmth feature also serves to amplify the results of the DUO Pod attachment, which holds a targeted serum of your choice that’s evenly distributed to your scalp as you comb the device through your hair. There are three different serums based on different scalp needs, but each one is silicone-free, cruelty-free, and vegan. If hair growth is your primary goal, the Boost Pod is a lightweight serum that’s formulated with caffeine, niacinamide, peptides, and green tea leaf extract. Caffeine is believed to help stimulate hair growth, while the brand notes that the copper peptide in the serum has been shown to give similar hair growth results as the topical treatment minoxidil. Meanwhile, the niacinamide and green tea leaf extract help to calm the inflammation that can contribute to hair loss, and they work with hydrating ingredients like panthenol, aloe vera, and hyaluronic acid to moisturize the scalp. For something more moisturizing, the Balance Pod combines argan oil with castor seed oil and red raspberry seed oil for a more nourishing serum that’s also rich in antioxidants to help shield your hair from environmental and heat damage. And finally, if you’re looking for something to soothe scalp irritation, there’s the Awaken Pod that’s formulated with tea tree oil, an ingredient that’s naturally antifungal and antibacterial. You’ll get two pods with your purchase of the DUO device, but you can also purchase the pods separately.
