"Permanent" Laser Hair Removal

{{ voteCount >= 0 ? '+' + (voteCount + 1) : (voteCount + 1) }}

I feel that laser hair removal is overpromised as being "permanent" and that "you will never have to shave, wax, tweeze, etc." ever again - it's just not possible. Single hairs may be permanently removed if the follicle is destroyed. That single follicle will not regrow. However, the best you can expect from laser hair removal treatments is 70% of the hairs to be totally removed. The remaining hairs should be more fine, thin, and lighter in color. Additionally, over time, your body will develop new hair follicles, so new hair growth will occur. This is why it's recommended that after the initial 6 treatments, you undergo maintenance treatments every 4-6 months so that new hairs are targeted. So to answer your question briefly - yes, SINGLE hairs are permanently removed. 100% total removal of all hairs is impossible.

Laser hair removal can be permanent

Lasers create a beam of highly concentrated light that penetrates deep into the skin where it delivers a controlled amount of therapeutic heat. This light energy is absorbed by the pigment located in the hair follicles. The laser pulses for a fraction of a second, just long enough to destroy numerous follicles at a time and leaves the surrounding skin unaffected. Permanent hair removal depends on hair color, skin color, and the strength of the laser treatment as tolerated by the patient. Up to 15-30% permanent hair loss may be observed with each treatment when optimal parameters are used.

Permanent Reduction

Laser hair removal is designed for the permanent reduction of unwanted hair. Therefore, it is permanent but because hair in a single area grows at different rates the technology is only designed to target actively growing hair, you'll need more than one session to achieve desired results.

Laser hair removal is considered more permanent reduction than permanent removal. Laser hair removal is very effective for the treatment of dark hair and we can treat all skin types . You can expect about 70 % hair reduction once you complete a series of treatments (usually 6-8) .
Follow up visits are needed to treat regrowth and to maintain the results. Factors like heredity, hormone imbalances and reactions to medications can also determine the results, however, my patients are very pleased with their results

Laser Hair Removal vs. Laser Hair Reduction

{{ voteCount >= 0 ? '+' + (voteCount + 1) : (voteCount + 1) }}

There is a big difference between claiming permanent hair reduction and permanent hair removal.  Permanent hair removal implies that there will be no regrowth, whereas with permanent hair reduction you may seem some regrowth of fine, thin hairs.  Patients should expect that after a full course (usually 6 treatments) they will need a single booster treatment roughly annually to maintain their results.  Certainly, the characteristics of your hair have a major impact on how effective the treatment is.  Generally, the darker and thicker the hair the more effective any kind of laser hair removal is.  Another variable is the pigment in your skin.  All of these issues should be discussed in detail during your initial consultation.

Laser Hair Removal and Permanent Reduction

{{ voteCount >= 0 ? '+' + (voteCount + 1) : (voteCount + 1) }}

Laser hair removal is amazing and permanently reduces hair growth.  At times, if there is a hormonal influence it may not be permanent.  However, in general, laser hair removal is a permanent way to remove hairs.  Many of my patients have called laser hair removal "life changing" because they no longer have to worry about waxing or shaving or ingrown hairs.  Please consult an expert in laser hair removal for the best cosmetic results.  Best, Dr. Green

Laser hair removal uses and intense, pulsating beam of light to remove unwanted hair. The intense heat of the laser damages the hair follicle, which inhibits future hair growth. Laser hair removal is most effective for people who have light skin and dark hair. Laser hair removal is considered more permanent reduction than permanent removal. It takes 6-9 sessions to see 70%-90% reduction in hair growth.

LASER hair removal is best described as permanent hair reduction.  In some individuals, certain areas such as a women's legs or underarm area can have permanent reduction in hair.  Other areas, such as female facial hair or male back's may require multiple sessions on an ongoing basis to keep hair from regrowing.  Even though for those individuals laser hair is not "permanent', it still maintains a high satisfaction rate as the type of hair is often changed to a finer hair and the overall amount of hair is dramatically reduced with a full series of treatments.

Laser hair removal results in a permanent reduction in the number of hairs. It can only address existing hairs. The laser cannot prevent new hair from growing. Hair growth cycles are different, depending on individual factors such as: heredity, hormone imbalances, resistance to insulin, pregnancy, thyroid issues, reactions to medications and aging.
