Laduora Duo 4-in-1 Red Light Therapy Scalp and Hair Care Device Review: Custom Goals

This device looks exactly like a high-tech brush. It plugs in via a USB cable and takes about four hours to fully charge, then lasts for 60 minutes (about 12 five-minute sessions) on a single charge. There’s only one button to turn the brush on and off, and with the button, you also toggle through three modes: Gentle, Balance, and Boost. There’s not much information about the different settings, but each increases the overall intensity of the vibrations, which are felt through small, circular metal nib bristles that vibrate the scalp in short, resonating intervals. These hairs are short, stiff and do not move, so be careful as they can get caught in matted hair (more on that below). After a five-minute session, the device automatically turns off.

For best results make sure your hair is (mostly) clean; You can use the device on dry or wet hair. Make sure all the teeth of the brush are touching your scalp, then you will brush from front to back and side to side or in a circular motion to cover the entire area of ​​your scalp. The brush has a center hole where you insert the serum pod, which comes out through the brush tips to enhance the desired results. The Boost Serum (which came with my test unit) aims to tackle thinning and flaking; Balancing restores the scalp’s natural pH with rosehip, raspberry seed, argan and castor oils; And Awaken provides soothing, cooling relief to irritation with a blend of peppermint, tea tree oil and aloe extracts.

Whichever formula you choose, each two-pack of pods costs $30 and lasts about nine sessions, which means you’ll have to repurchase them every two to three weeks if you use the pods daily. You can purchase replacement pods only through Laduora’s website. The device is usable without the pods, but treatments will no longer have serum benefits. My hair looked quite shiny with less frizz while using the serum, but it left my hair looking a little greasy afterward (despite Laduora’s claims that this wouldn’t happen).

When on, the brush device heats up to 108 degrees Fahrenheit to increase blood flow and allow the pod contents to be absorbed deeply into the scalp, follicle and hair shaft. However, the effect I felt most physically was the vibration. Moving teeth is similar to a semi-scalp massage, which helps reduce stress and promote blood flow. The tingle you feel when someone plays with your hair or lightly scratches your scalp with their fingers, I felt it. Microcurrents work with heat to promote blood circulation and hair growth by stimulating the follicles. It was hard for me to differentiate between microcurrent and vibration, because microcurrent also produced low vibrations that felt similar.
