How do they work?


The lasers radiate low light treatment to the skin’s tissue on the scalp. Thus, the blood starts stimulating the scalp. The blood circulation will provide oxygen to the air follicles that help in regrowth. When the light goes in the scalp the cells absorb the light and start protein synthesis. When the damaged cells get healthy again, they again start the regrowth process.


Revian uses LEDs to cover the whole scalp. They use lights of 2 different wavelengths, 1 of 620 nm and the other is 660nm which is safe and approved by FDA. Both of these waves provide nitric oxide to your hair and enhance the hair cells to grow again naturally and due to this natural procedure, these hairs are thicker and stronger. Furthermore, to increase the period of this procedure they also use DHT.

Duration of Therapy

Kiierr therapy sessions consist of 30 minutes and you need to use it once in 2 days to work effectively. 30minutes are significant and recommended for diodes to work effectively.

Because Revian uses LEDs that is why you can use it every day for just 10mins and their mobile app will also remind you daily and track your progress as well.
