Chapter 4: Hair Removal Flashcards
How does selective photothermolysis work (basic principles of hair removal)?
- light is absorbed and heats the selected target
- when the temperature reachers 70C the follicle is destroyed
- the specificity of this process enables us to selectively destroy a lesion without damaging the skin
In what stage does a hair follicle have to be in in order to reach the necessary 62-70C?
Only follicles in Anagen stage can reach follicle necrosis temperature 62-70C

Describe Hair follicle distribution:
- our entire body is covered with follicles-apart from the palms and feet
- however not all follicles actively grow hair
How many types of hair follicles are there?
Two
- Active follicles
- grow hair in cycles at a rate of about 0.33mm per day - Dormant follicles
- do not grow hair, but may become active due to hormonal changes and other reasons
Name the Hair Reduction hand pieces:
- HR 580: skin type I-IV
- HR 635: skin type ?
- HR 730: skin type ?
How to operate Application Screen (user friendly DPC screens)
- simply select the skin type & hair type
- the appropriate pre-programmed DPC treatment will automatically set
- The default safety values will be loaded automatically/ 100,000 pulses per HP

Treatment Protocol:
What to remember before performing a treatment:
Do NOT treat patients with contraindicated medical conditions without permission from a physician
- Absolute contraindications
- Relative Contraindications
- Please refer to Chapter 3
- Refer to your User Manual
When seeking approval:
If unsure, the physicians permission should be in writing and include:
- the patients specific medical condition
- details of the intended treatment
- permission to perform the treatment, taking into account the patients medical condition
*the permission should be documented in the patients records
Immediate tissue response may include the following:
-stinging sensation while pulse is emitted
-smell of burnt hair
-an expected late (10-15) reaction may include
—follicular and or perifollicular reaction
Post treatment instructions for hair removal:
- immediate cooling
- sun protection (30 SPF at least)
- avoidance of sun exposure, artificial tanning and dirt/ debris
- cleaning and moistening during following days
*remember: tanning after treatment may enhance melanin regeneration which may result in hyper pigmentation
Treatment of Adverse Effects:
- treatment should be discontinued until site has healed. Patient should return for examination after 3 weeks
- If, after site has healed, results can be observed, select a darker skin type (or longer pulse duration and smooth pulse mode) and/ or lower fluence for the following treatment
- If adverse effects are observed and results cannot be observed, the patient should wait another 2-4 weeks and return an additional examination
- if no results can be observed during second examination, it should be determined whether the adverse effects were due to the fact that the patients skin was tanned
- if the adverse effects were not due to tanning, the treatment should be ceased until any medical condition is further investigated
