Laser hair removal is so great we now wonder how we got by without it! But how does it work?
To help you understand laser hair removal, we'll first begin by describing what the laser does, and then we will give you some information about the way the body grows hair and what this means for laser hair removal.
Both types of lasers that we use have been approved by the FDA for safe and effective hair reduction. During treatment, the laser emits a pulse, which travels through the skin and is attracted to the darkness of the hair. The laser then heats up the hair's shaft and root, destroying it. Because the follicle is eliminated, it is unable to re-grow hair. The Dynamic Cooling Device™ of our Candela GentleLASE Plus® laser emits a highly focused spray of coolant on the skin just before each laser pulse, targeting the exact area. This process protects the epidermis from overheating, burning, and scaring while reducing any discomfort.
So, a damaged hair follicle means no more hair. Because the laser effectively targets many hairs at one time, lots of follicles are destroyed at once. This allows us to remove the hair of large areas in a very quick treatment session.
Below is some additional information that will help you to better understand laser hair removal, and the factors that affect hair growth. The human body has a mixture of hairs with varying amounts of melanin, also known as dark pigment, and a combination of activated hairs that are cycling through the growth cycle and hairs that have not yet become active. Most importantly, many factors such as hormones, age, ethnicity, weight, metabolism, and medication all influence the body’s hair growth.
Laser hair removal can only occur during this active growth stage.
Hair follicle shrinks and detaches from the dermal papilla.
The dermal papilla completely separates from the hair follicle.
Part of the resting phase where the old hair sheds and a new hair begins to form.
There can be as many as 2,500 hair follicles per square inch, however less than 100 hairs are actually actively growing. The hairs that are inactive are “waiting” to be activated by hormones. This is why many people experience heightened amounts of hair during puberty, and less amounts of hair in some areas as we grow older, such as the head, and more in other areas, such as the ears or back. Our genetic makeup tells our body when to produce more or less hormones, thus affecting our hair growth. Hair must be in the active anagen phase to be treated by laser; this is why treating a young child before puberty will not prevent future hair growth during puberty, it will only kill the hair they have actively growing at that time.
Your certified laser technician will determine the correct spot size and laser fluence based on your body area and skin type. Hello Laser has the fastest, newest lasers available so we'll get your treatment done lickety split!
The treated hairs will begin to shed in about 10 to 14 days. These can be left alone or buffed out with a body scrub, loofah or exfoliating gloves.
After your hair has fallen out, you will notice smooth skin for a week or two. Then hair will begin to grow again, as new follicles start to enter the anagen growth stage. You will want to schedule your next treatment some time between 4-6 weeks from the first appointment, depending on the body area.
After 4-6 weeks, you should have new hair growth. Now it's time to zap that next set of follicles! This schedule will be repeated about 8-14 times until you've achieved smooth hairless skin.
After Treatments are Finished
The average customer is satisfied with their hair removal after 6-8 treatments (8-12 treatments with the YAG Laser). It is important to remember that each individual’s age, ethnicity, weight, metabolism, medication and hormones have a direct result on hair growth and can affect their laser hair removal process. At Hello Laser, we think that everyone should have an affordable way to achieve satisfaction, so for those customers that may need more than 10 full treatments on any body area, we offer HALF OFF of our price for that body area! Swell!
