Laser Hair Removal… All Questions Answered

There’s something about 7 women in a closet sized room, lasering each other’s hair off (Brazilian being one) that brings a sense of closeness.

After a fun-filled week with these amazing women, I feel compelled to write all I have learned about laser hair removal.

First and foremost, What does “LASER” mean?

Did you know the word “LASER” is an acronym which means…
Light
Amplification by
Stimulated
Emission of
Radiation

The term “radiation” is often misinterpreted because the term is also used to describe radioactive materials or ionizing radiation. The use of the word in this context, however, refers to an energy transfer. Energy moves from one location to another by conduction, convection, and radiation and cannot alter DNA structure.

How does it work?

Basically, lasers cause localized damage to the hair by selectively heating dark target matter, melanin, in the area that causes hair growth, the follicle, while not heating the rest of the skin.

 

Is every laser created equal?

No.  Different companies have different names for their lasers, but the two main lasers out there today are: Alexandrite (755) or the “Alex” & YAG (1064).  This one in particular is what I was trained on and is the latest.    It actually has both Alex and Yag in one machine!  Don’t quote me on this, but I don’t think there’s another two-in-one out there right now.  Very convenient since both are significantly different from each other.  Why?…

 Alex vs YAG… What’s the difference?

Alex (755)-

  • Attracted to melanin (treats hair and pigmented lesions)
  • Great on fair skin (skin types I – III).
  • Not recommended for skin types IV – VI.
  • No sun exposure for at least 4 weeks prior to treatment.
  • Better on thin hair.
  • Most report less discomfort than “YAG”.
  • More effective laser (usually less treatments are needed).

Here’s a perfect example of a skin type II ideal for the “Alex” laser…

YAG (1064) – 

  • Attracted to melanin and hemoglobin (treats hair, pigmented lesions, loose skin, veins, wrinkles, enlarged pores, tattoos, pseudofolliculitis barbae commonly called “ingrown hairs” or “shaving bumps”, and toe nail fungus… Yes. Fungus!)
  • Safe for every skin type (I – VI).
  • Can be used on sun exposed skin (3-4 days post).
  • Effective on thick, coarse hair.
  • Not ideal for thin textured hair.
  • Many report more discomfort during treatment than “Alex”

Definitely a “YAG” candidate in the pic below…

How many treatments are needed? 

Hair grows in several phases (anagen, telogen, catagen) and a laser can only affect the currently active growing hair follicles (anagen). This is why several sessions are needed to kill hair in all phases of growth.

The actual number of sessions depends on various parameters, including the area of the body being treated, skin color, coarseness of hair, reason for hirsutism, and gender.

Average number of treatments:
Face: 6-10 treatments every 4-6 weeks.
Body: 4-6 treatments every 8-12 weeks.

Can all hair colors be treated?

No.  Laser does not work well on light-colored hair, red hair (sorry Carrot Top), grey hair, white hair, as well as fine hair of any color, such as vellus.
Coarse dark hair on light skin is easiest to treat (ideal candidate: Snow White… or the guy below will do).

What are the most common side-effects and risks?

During treatment: discomfort.

Post treatment (most common): itching, redness, and swelling (perifollicular edema) around the treatment area. These side effects rarely last more than three days.

Unwanted side effects and risks:  hypo- or hyper-pigmentation, blistering, scarring, skin texture changes, flare of acne, swelling around the hair follicle, scab formation, purpura, infection and burning of the skin.

What areas can be treated?
If it grows hair.. Then, yes it can be treated (as long as there isn’t any underlying contraindications).

What are the contraindications?

In other words, if you have any of these conditions or are taking any of the meds listed, you CANNOT be treated?

  • Pregnant
  • Gold Therapy (If you don’t know what this is, then you have never had it)
  • Light induced seizures
  • Anyone taking photo-sensitive meds (if you are, then you need to wait 3 weeks)
  • Accutane (need to be off for 6 months)
  • Anticoagulants
  • History of skin cancer
  • Suspicious pigmented lesions
  • Lupus
  • Herpes (pre-treat with an antiviral drug such as Valtrex… But, if active, cannot be treated until dormant again)

How do I prepare for laser hair removal?

  • No waxing, tweezing, or electrolysis for 4 weeks prior.
  • If you have fair skin (skin types I -III), no sun exposure for at least 4 weeks.
  • If you have darker skin (types IV – VI), no sun for 3-5 days.
  • No threading for 10 days
  • No self-tanner for 14 days
  • Shave the area being treated the same day or the night before
  • No make-up, lotion or deodorant should be worn on the day of your treatment
  • No topical Retin-A for 3-5 days
  • No oral Retin-A for 3 weeks
  • No Accutane for 6 months

How much does it cost?

Clearly, prices are going to vary from country to state to city to town…
Prices can range anywhere from $100 per area per treatment to $900 per area per treatment (all depends on the size of the area and amount of hair).  Yes, it can be costly, but let’s take into consideration the amount of money we all spend on razors, waxing, threading, plucking.

Are there any post-treatment instructions?

Yes!.. And please follow strictly.

  • No sun exposure for 1 week (if blistered or burned, then stay out of the sun until healed… unless you want to scar)
  • Apply cool compresses to red or swollen area.
  • No Retin A for 24 hours
  • No direct heat for 24 hours (ie: hot showers.. This is a tough one for me, since I truly love mine… but I do follow this religiously as I have learned the hard way.. hehehe)
  • It will look and feel like a sunburn… treat it like one!
  • Lastly, enjoy being HAIR-FREE!

Hugs,

  1. I really liked how you answered all the questions about laser hair removal. I haven’t tried it yet but since I knew some of the important pointers, I could now. You can also check out the story about no no device and if it is equally effective.

  2. Lasers are useful for removing unwanted hair from the face, leg, arm, underarm, bikini line. So a concentrated beam of light is aimed at hair. But result might we differ from patient to patient.

  3. I love the fact you have called it ‘laser hair removal’ and what your talking about is ‘laser hair removal’, the general term for IPL hair removal is also termed as laser hair removal and it is very confusing. Along with your great blog i have read another which talks about yag lasers and ipl machine for hair removal
