How Does Pain Free Laser Hair Removal Work?

Before we get into how pain free laser hair removal works lets us first start with the Hair Growth Cycle. There are 3 stages of hair growth Anagen, Catagen, Telogen. A great way to remember the stages of growth is the acronym ACT The Anagen phase is when the hair is actively growing. The Catagen phase is when the hair is in the root but not attached to the bulb and is no longer growing. The Telogen phase is when the hair falls out of the root and rests to grow a new hair. All the follicles on the body go through the 3 stages of hair growth in about 6 months to 2 years.


The key phase in which the laser works is the Anagen phase. The laser is attracted to hair with color (does not work on blonde, gray or white hair) When we go over the hair with the laser the pigment in the hair is attracting the heat to then travel down and singe the bulb and the vessel so that you no longer get nutrients to grow a hair. Once we have achieved this it takes 10 days to 2 weeks for the hairs to fall out. Then in about a month there are new hair follicles coming out that are in the Anagen phase so then it is time to laser again.

Our laser the Soprano XLI is the latest in laser technology. It is a diode laser meaning it is a single wavelength that targets the hair. Since it is a Diode laser it is safe for darker skin types as well as people when they are tan. The laser in an inmotion technology laser so we gradually heat the hair follicles which is what makes it PAIN FREE.

The most frequently asked question is: Is Laser Hair Removal Permanent? The answer is yes. The hair roots we have "killed" will not grow back. However, you have on your body "sleepy hair roots" that have never had a hair in your whole life or been active. Hormonal changes in the body can cause the "sleepy hair roots" to become active which is why people if they get new growth in an area sometimes feel it is not permanent. Hormonal changes that can cause the "sleepy hair roots" to become active are pregnancy, birth control, and menopause to name a few.
