Q: How does laser therapy work?
A: The actual mechanism by which Low Level Laser Therapy (LLLT) stimulates hair growth (i.e., increases the anagen phase of the hair cycle) is still unknown. Possible mechanisms include the following:
Q: I have been trying to find some evaluation of which laser combs work best for “hair restoration”. I have seen some dermatologists speak about the Hair Max laser comb and its effectiveness (considering patient compliance, the amount of time the patient has been losing hair, the amount of total hair loss at time of treatment, etc.). I have also seen reference to the Sunetic laser comb which claims to have a superior technology to the Hair Max and offers a changeable head to allow treatment of the skin for healing, wrinkles, etc. A company in Michigan also offers a laser comb called the Hair Rejuvenator which it claims is superior to either of the other combs but I have not heard of any dermatologist who recommends this comb. A firm in Australia also offers a laser comb (Aculas) which it claims is the most effective; however, the makers of the Hair Rejuvenator comb say it is too powerful and dangerous and could cause blindness. Amidst all these claims, the consumer (patient) is left wondering which best option is and which is merely hype or fraud. What do you suggest?
A: There are no comparative studies thus far. For a hand-held device, I would stick with the Laser comb for now since it is the only one that has cleared the FDA.
Some others may work as well (and are less expensive) but we just don’t know at this time – and how useful any of them are long-term is also still not known.
