When the words “laser” and “hair” are paired together, they’re usually followed by “removal.” But quite a bit of evidence actually shows that lasers can be used to promote hair regrowth in patients suffering from hair loss. This laser hair growth stimulation, often referred to as LLLT or low level laser therapy, is a fairly new technique, and you probably don’t know much about it even if you’ve been investigating hair loss solutions for a while. So here are your top three questions about laser treatment, answered:
- How Does Laser Hair Growth Stimulation Work?
LLLT is thought to catalyze a chemical reaction in cells that causes them to produce more or thicker hair. A specific wavelength of light in the red spectrum is used to achieve this effect. It’s not fully understood how LLLT works to promote hair growth, but because it is completely painless, it is a very low-risk treatment. It is often delivered via over-the-counter devices (such as caps) so that it can be used at home without physician supervision.
- How Effective Is Laser Hair Restoration?
All hair loss treatments vary in success among patients. However, it’s important to know that LLLT may not work for all patients, and you shouldn’t expect dramatic, overnight results. Most medical experts believe that LLLT can be an effective part of a hair loss treatment regimen (either alone or combined with other methods), but full results shouldn’t be expected until about six months after treatment begins. LLLT must be used on an ongoing basis in order to maintain its hair regrowth benefits.
- Who Is a Good Candidate for Laser Treatment?
LLLT is generally used to treat hair loss as a result of androgenetic alopecia (genetically predisposed hair loss, commonly known as male pattern baldness/female pattern baldness). It is generally most effective when started in the early stages of hair loss, and is often recommended by doctors if go-to medications such as Propecia and Rogaine have been ineffective.
