4 Things That Can Impact the Success of Laser Hair Removal


Women love the feeling of smooth, silky legs that catch the sunshine and accentuate their stride. We all dream of not needing to prepare to go to the beach, and wear a bikini or short shorts on a whim.

What we don’t think of as fondly is razors, bimonthly waxing appointments, or always deciding which hair removal creams will irritate our skin least.

With laser hair removal, all these stressors can be a thing of the past. If you’re considering this procedure, you obviously want the best results possible. At Etre Cosmetic Dermatology & Laser Center, we can offer you crucial advice on making sure you get the best out of your laser hair removal, and that unwanted hair truly becomes a thing of the past.

First, let’s take a glance at how laser hair removal works by understanding how hair grows.

How Does Hair Grow?

There are two parts to human hair: the hair follicle and the hair shaft. The follicle is what attaches the hair to the skin, and is responsible for new hair growth as the follicle receives nourishment from the blood supply. 

The shaft is the part of the hair visible to the naked eye and grows outward away from the follicle as new keratin proteins are synthesized.

The shaft grows in three different stages.

  • Anagen, or growth stage: The blood supply nurtures the hair follicle, which brings nutrients, allowing the growth of new hair.
  • Catagen, or transitional stage: The hair follicle detaches from the body’s blood supply, and stops growing due to the lack of nutrition.
  • Telogen, or resting stage: During this stage, the detached shaft of the hair rests above the hair follicle, while new hair begins to grow. The old hair will eventually fall out and get replaced by the new hair, thus perpetuating the growth cycle.

How Does Laser Hair Removal Work?

Laser hair removal works by focusing light energy onto the hair shaft. The laser super-heats the hair follicle, thus damaging it so it can no longer produce new hair cells.

It’s essential to remember that each strand of hair on our bodies is in a different stage of growth. Because of this, you’ll need multiple laser sessions to completely synchronize the growth cycles of each individual hair follicle in the treatment area.

With this knowledge, we can now apply four best practices to ensure we get the best out of our laser hair removal therapy.

1. Don’t Miss an Appointment

Now that you understand the growth cycle of your hair, it becomes clear why cosmetic doctors schedule a series of laser hair removal appointments.

We strategically time these appointments to provide the best overall results. When the lasers are focusing on the hair shafts, some hairs may only be at the anagen growth stage, and thus will not receive the energy from the laser. A few weeks after the initial procedure, these hair shafts will have grown and be ready for lasering.

As such, missing an appointment is detrimental to your laser hair removal results, as it risks desynchronizing the growth stages of your hair.

2. Use Your Razor

We know you’re opting for laser hair removal so you no longer need a razor. While you’re receiving your treatment regimen, however, you’ll need to use a razor to keep your hair short. Waxing and plucking remove the follicle, which gives the laser device nothing left to target. 

Switch from waxing and creams to a razor three weeks before beginning your laser hair removal treatment for best results, as this gives your hair the best chance to synchronize growth stages.

3. Choose the Right Skincare Routine

Some skin care products can influence the way the lasers interact with your skin pigments and hair, primarily increasing your skin’s photosensitivity and creating a risk of hyperpigmentation. Be sure to follow the advice of an experienced cosmetic practitioner when deciding on a skincare regimen before and after your laser hair removal.

4. Choose the Right Dermatologist

Inexperienced doctors would have you believe that laser hair removal is straightforward and risk-free. That’s because they don’t appreciate the complexities involved in understanding your body’s natural hair growth cycle, and the interactions between specific products, treatments, and skin types.

The best way to ensure you get the most out of your laser hair removal treatment is by choosing an experienced, certified, and qualified cosmetic surgeon and board-certified dermatologists such as Lisa Donofrio, MD, or a rising star in the field such as Kyle Coleman, MD.
