There’s been a lot of buzz recently about Low-Level Laser Therapy (LLLT) for hair loss. There are plenty of claims that it can produce results. You may have noticed an increasing number of LLLT hair loss devices for sale like laser combs and caps and you might wonder if it’s too good to be true. It’s not always easy to sort the hype from the reality.
Here are the facts you need to know about LLLT for hair loss and whether it could work for you:
What is LLLT?
It is a low-energy laser to stimulate the hair follicles all over the scalp.
LLLT is a non-surgical hair loss treatment that uses laser light to stimulate
cell growth and boosting hair follicles. It may help to defend hair loss
and improve the volume of hair. There is no pain and no side effects.
FDA approved it as a hair loss treatment for both men and women. Because the main cause of hair loss is androgenetic alopecia it is used mostly to help with this condition, but LLLT can help for other causes of hair loss such as shock loss after surgery or pregnancy or hair loss after chemotherapy or sometimes alopecia due to some skin conditions. It also can be combined with hair restoration procedures, medication therapies or platelet rich plasma. But the truth is that although we can expect some results with LLLT, but the effects is different from one person to another person and there is no guaranty in getting results by LLLT.
What is the mechanism of LLLT?
The exact mechanism by which LLLT stimulates hair growth is not fully understood, some research claims the effect is like minoxidil and can increase blood flow. Others believe mitochondria of hair follicle cells are target for LLLT and cytochrome C oxidase has been suggested as key molecule that absorbs energy of LLLT devices.
How many sessions do I need for LLLT?
Patients need a course of treatments usually between 5-10 sessions every two weeks.
