The Science Behind Laser Hair Removal

Laser hair removal is the safest and most efficient solution for permanently ridding yourself of unwanted hair. It’s popularity as one of the most sought after non-invasive cosmetic procedures is not surprising, as so many people can now enjoy the lifestyle of lasting smooth skin and the convenience of no longer having to shave.

Hair Growth

Lasers treat hair follicles best when they are in their active state of growth. Because hair has three phases of development; Anagen (the growing phase), Catagen (the resting phase) and Telegen (the shedding phase) not all hairs are simultaneously growing. As a result, multiple treatments are needed to achieve the highest levels of permanent hair removal.

How Laser Hair Removal Works

The pigment in the hair follicle absorbs the energy produced by the laser, resulting in its destruction and preventing the hair from ever regenerating. To achieve this result, the hair follicle must contain the needed pigment to absorb the laser’s energy. As such, white and grey hair is non-responsive. Light brown and red hair may be treated, but not as effectively as darker hair. As a general rule, hair must be darker than the surrounding skin in order to be effectively treated. In our office, all skin tones can be treated effectively thanks to our dual Alexandrite & Yag lasers.


Safe and effective treatment is achieved by destroying hair follicles without causing damage to the epidermis (the tissue making up the skin composition surrounding the hair shaft). In selecting optimal treatment settings, the clinician must balance many variables, which is why the right laser platform combined with a highly experienced clinicians is essential.

At New Life Laser, we take pride in our highly trained and experienced clinicians. Over the years, we have performed tens of thousands of treatments and have perfected a system that allows us to offer the best guarantee in the industry! With our microscopic laser result analysis, We are able to highly customize laser settings to skin tone, hair coarseness and hair color, etc. Using our laser results system, we are able to precisely select optimal levels of energy to destroy the hair follicle while maintaining FDA approved safety parameters that are designed to prevent injury to the epidermis. 

Our certified laser professionals coupled with our unparalleled laser technology, ensures that you receive the highest value, safety, and quality of treatment in today’s laser hair removal market. This is what we like to refer to as “The New Life Laser Difference!” Is Lasting smooth skin: once we destroy the hair follicle, it will never produce hair again. Any remaining hair follicles will produce hairs that are lighter and thinner, requiring much less attention than before. Again, we offer clearance of roughly 85 - 95% with some variation from person to person. New hair follicles may form over time as a result of aging, hormonal changes, dormant hair follicles, and individual genetics. For these reasons, some clients elect to schedule touchup treatments to maintain their results.
