Are The Results Permanent?
Laser hair removal causes permanent hair reduction and delayed re-growth of the treated hair follicles. Also, re-growing hair is often smaller in caliber and lighter in color than previously.
Many things influence hair growth. Your age, ethnicity, weight, metabolism, hormones, medication, etc. Each play a role in your hair’s resilience, thickness and areas of growth. Part of the challenge in eradicating unwanted hair lies in the fact that the follicle has regenerative capabilities and that these recuperative powers are highly variable from individual to individual and from one anatomic site to another.
You may need an average of 3-6 treatments because only hairs in the active growth phase, anagen, can be successfully treated. More than one treatment is required to disable hair follicles that subsequently enter this growth phase. The treatments are 6-8 weeks apart for the body and 4-6 weeks apart for the face.
What Happens To The Skin After The Treatment?
Within several minutes of the treatment, the treated area may become slightly red (erythema) and bumpy (perifollicular edema) in some cases. This is a good clinical end point that the treatment was effective. This will resolve within 20 minutes to two hours after treatment. No significant discomfort should be felt after the treatment. You are able to reapply your make-up, return to work, and continue with your daily activities.
Hair should appear to grow for several days post treatment as the hair is extruded. Hair should spontaneously fall out between days 4-14.
Hair Growth Phases
Anagen: The phase of the hair cycle during which synthesis of hair takes places. This is the active growing phase in which the hair bulb is intact. The hair grows in both direction, upward and downward. Early anagen is when the bulb is closest to the surface of the skin allowing for the most efficacious treatment.
The time span for this phase is measured in months/years.
Catagen: Brief intermediate phase between anagen and telogen. During this phase, the body absorbs the lower third of the follicle. The time span for this phase is measured in weeks.
Telogen: This is the resting phase. The hair bulb is no longer present. It is now a bulb of hair, which will fall out of be pushed out by the follicle by a new anagen growing hair. The time span for this phase is measured in weeks/months.
