Lifecycle Of A Hair Follicle

​Anagen (the growth stage) The hair is thickest and darkest, so laser treatments are most effective.

Catagen (the transitional stage) The hair begins to loosen from its follicle.

Telogen (the resting stage) The hair is resting and remains in its follicle but is not actively growing.  

Exogen (the shedding stage) The hair is released from its follicle and falls out.


The hairs on your body are not always at the same stage, so you will need to set up a customized treatment plan designed for you.

How Do I Prepare For A Gentle Hair Removal Treatment?

  • On the day of your treatment, skin should be clean-shaven and thoroughly cleansed of any makeup, creams, oils, topical anesthetics or self-tanning products.

  • Do not expose the treatment area to sunlight or tanning booth light prior to or immediately after treatment.

Pre Treatment Instructions

  • No tanning and/or fake tans from spray on, creams or products that tan.

  • No waxing, tweezing, threading, creams or depilatories. Trimming or shaving is fine.

  • Shave the whole area to be treated, the evening or am before your appt. get close but do not cut your skin. Heat up the new shaver for a minute under hot water, this helps to soften the razor.

  • On the day of treatment no lotion, makeup, perfume and deodorant should be used on the areas to be treated and be clean.

  • If you are taking Accutane, or have taken it in the last 6 months please discuss with practitioner before your appointment day

  • No vigorous exercising for the rest of the day after treatment.

  • No lotion, makeup, perfume and deodorant should be used on the areas treated for 24 hours.

  • No very hot shower but a warm shower is recommended to remove hair debris and cooling spray.

  • No swimming in chlorine water for 24 hours

  • After treatment, you may experience redness, swelling or irritation which subsides within a few hours or longer.

  • First week after the treatment avoid exfoliating the treated area.

  • One to four weeks after the treatment, you should experience shedding of hair in the treated areas. At first, it will feel like the hairs are growing back in or little black hair dots stuck under the skin, but these are the treated hairs coming through the skin and will shed off.
