The iGrow® Hair Growth System — a helmet-like, at-home, low-level light laser therapy (LLLT) device, previously approved for men — has now been approved for women with androgenetic alopecia (pattern hair loss).

Apira Science, which manufactures the device, states that the iGrow system “energizes cellular activity within the hair follicle,” increasing its metabolic activity and leading to new hair growth.

iGrow, a low level light laser hair growth system, previously approved for men, has now been approved for women.

Two studies using the device, published in the journal Lasers in Surgery and Medicine, found that the iGrow increased hair growth in men and women with androgenic alopecia by an average of 35%1 and 37%2 respectively.

Apira recommends using the iGrow Hair Growth System for 25 minutes every other day for 4 to 6 months before expecting to see results.

The iGrow incorporates a proprietary dual light Laser and LED design and comes equipped with headphones and an iPod/MP3 interface that connects to most audio devices.

The iGrow is not recommended for those with alopecia areata or those who have severe hair loss.
