Low-level Laser Therapy (LLLT) for Hair Loss Prevention

Low-Level Laser Therapy (LLLT) is a non-surgical hair loss treatment that uses laser light to help slow the rate of hair loss and stimulate cell growth. Using LLLT helps to combat hair loss and can potentially improve the volume and appearance of hair. And the great news is that therapy is painless and takes as little as 6 minutes per day.


LLLT has been used in medicine for 60+ years to accelerate healing and to reduce pain in many different disciplines in medicine. For hair loss specifically, LLLT was first written about academically almost 30 years ago in 1992. We’ve come a long way in research since then to the point where, in 2007, the FDA cleared low-level lasers for the treatment of androgenetic hair loss.


LLLT can also be used to treat other forms of alopecia and hair loss that happen because of chemotherapy, pre- and post-pregnancy hair loss, and hair loss brought on by menopause.


At Anderson Center for Hair our surgeons also use LLLT alongside other hair loss treatments including PRP and hair transplant procedures.

Frequently Asked Questions

How does Low-level laser therapy work?

LLLT uses laser energy in the red and near-infrared spectrum which can be absorbed by the molecules of your skin and hair follicles. The energy helps hair follicles grow in multiple ways:

  • When laser energy penetrates the scalp it stimulates the stem cells responsible for the regeneration of the hair follicles, encouraging hair regrowth.
  • LLLT works to increase the production of ATP and speed up the metabolic process of the cells with the goal of faster hair growth.
  • The light increases blood flow in the targeted region of the scalp which in turn increases the delivery of nutrients and oxygen to the hair follicles, allowing them to grow thicker and longer.
