About the Procedure

Last Updated: 07.27.2021

Hair loss can occur due to hereditary predispositions, stress, medications, or certain skin conditions. While the cause may vary, treatment options are relatively the same with hair restoration being most effective when an intervention is made early on in the hair loss stages. Medications, topical products, and hair transplant surgery can all be used to treat thinning hair but can include unwanted side effects and a high cost. At home, low level laser therapy (LLLT) has been touted as an alternative to its riskier and more invasive counterparts. The Kiierr laser hair cap system offers patients discreet, affordable hair loss treatment in the comfort of their own home. The Kiierr laser hair cap system looks like a baseball cap but underneath, houses between 148-272 laser diodes depending on the model. These diodes emit laser energy which stimulates dormant hair follicles by encouraging blood flow to the scalp area. The hair growth phase is extended resulting in healthier thicker hair. No special measures need to be taken prior to using the Kiierr laser hair cap. The user will wear the Kiierr cap for a period of 25 minutes, during which the wearer is able to read, watch TV, or do other activities as the system is portable. Once the treatment session is done the cap is removed and no downtime is needed. Treatments should be repeated every other day.

The goal of Kiierr laser hair cap system is to reduce hair miniaturization while also increasing hair growth and thickness.
