Laser hair removal is one of, if not, the newest permanent hair
removal methods available today. This method of hair removal
has steadily increased in popularity and is steadily improving.
Laser hair removal offers fast treatment time and minimal discomfort
when compared to another method for permanent hair loss hair electrolysis.
Permanent removal of hair may
be achieved through several treatments of laser hair removal. Results
reported by individuals who have undergone treatments have been
very positive, with some people achieving between 60% to 80% hair
removal after a maximum of three treatments. Majority of people
who have undergone laser hair removal experience results of up to
50% less hair in the first four months after the first session.
The hair that grows back tends to be finer, smoother and sparser.
Repeated treatments ranging from six to twelve months may be needed
to get rid of all the hair permanently.
Laser hair removal is based on the principle of selective photothermolysis. The laser is turned on for a fraction of a second, emitting a beam of light onto the skin. With the use of a hand piece, lasers emit wavelengths of light that are designed to be absorbed by melanin, the pigment in hair. The energy of the laser is concentrated on the hair strand, destroying it.
Although based on the same principle, all laser
hair removal equipment work in varying ways. One of the first
equipment to be approved is produced by San Diegos ThermoLase Corporation
the Nd:YAG laser. This laser requires that the skin be pretreated
using wax to remove the hair strands and open the hair follicles.
This needs to be done to allow the laser light to reach the follicles
effectively. A light-absorbing lotion is then massaged onto the
skin before the laser is passed over the skin. Newer lasers use
alexandrite lasers or long-pulse ruby lasers and do not require
waxing or the use of carbon-based lotions.
One treatment session generally lasts between one to three hours. Laser hair removal sessions involve the cleansing of the skin and the trimming of all unwanted hair. A dermatologist or certified nurse will then scan the skin area using the laser. The treated area will then be covered to prevent infection after treatment. The area is to be kept covered using a moist solution for a set period of time to promote healing.
The cost of laser hair removal treatments may vary depending on the number of sessions; however, the typical cost for laser hair removal for areas such as the face ranges between $800 to $1,200 USD. Removal of hair for other areas such as men’s backs can cost up to $3,000. To determine the exact cost of a procedure, a personal consultation with a laser hair treatment facility will need to be done.
There are several advantages to laser hair removal. One of the most prominent
is the permanent reduction of hair. Another advantage is the safety
of the procedure when performed properly and by licensed professionals,
and the area of effect lasers can be used on backs and legs. Similar
to other types of hair removal methods, laser hair removal also has
its disadvantages. Most of the disadvantages relate to the lack of
data on safety and effectiveness of this type of hair removal. Another
disadvantage is the cost of the treatment.
