Q

what does the hair papilla do

A
  • necessary for hair growth and nourishment of follicle

Q

how does hair grow

A
  • cell division of matrix occurs and hair grows longer

-keratinization completes by time cells approach skin surface

  • hair matrix divide to form 3 layers

Q

sebaceous gland

A
  • secretes waxy substance called sedum

-lubricates skin and hair

-keeps skin supple and waterproof to protects against external factors

22
Q

arrestor pili muscle

A
  • contract when affected by cold or other stimuli
  • pulls on follicle and forces hair to stand erect, causing goosebumps
23
Q

what are the types of hair

A
  • lanugo
    -vellus
    -terminal
24
Q

lanugo hair

A
  • soft downy hair
    -found on fetus
  • sheds after birth, replaced with vellus or terminal
25
Q

vellus hair

A
  • found in areas not covered by coarse terminal hair
  • peach fuzz
  • removing vellus hair can result in follicles producing terminal hair
  • not recommended to tweeze, shave or wax
26
Q

Terminal Hair

A
  • longer coarse hair found on the head, brows, lashes, genitals, arms and legs
  • hormone changes during puberty causes follicles to switch from vellus to terminal
27
Q

what are the stages of hair growth

A
  1. anagen phase - new hair produced
  2. catagen phase - transition phase
  3. telogen phase - final/resting stage
28
Q

Anagen stage

A
  • new cells from hair and root sheaths and used upward
  • can remain in anagen for weeks to years , depends on location
  • scalp hair remains in anagen in years
  • best phase for aestheticians
29
Q

what hair phase is best for aestheticians

A

anagen phase- most effective

30
Q

catagen stage

A
  • mitosis ceases, hair detaches itself from papilla
  • follicle degenerates and collapses
  • hair loses inner sheath and becomes dryer
  • mature hair referred to as club hair
  • shortest phase of the cycle
31
Q

telogen phase

A
  • club hair moves up follicle ready to shed
  • hair at full size and length

-erect in follicle, showing above surface

  • hairbulb is not active
  • hair released and only attached by epidermal cells

-may sit in follicle until pushed out by new anagen or falls out

32
Q

what is hypertrichosis

A

-excessive hair growth in areas hair normally doesn’t grow vellus hair

  • can be waxed, may not cure
33
Q

why does hypertrichosis occur

A

-genetics
-inherited
- ethnicity
- puberty
- pregnancy
- menopause
- medical procedures/treatments
- reaction to medications

34
Q

Androgens

A

-hormone in male when they go through puberty

  • women with high androgens have disorder that can cause growth of beard, or air in unusual places
  • harder to wax
35
Q

what is hirsutism

A
  • excessive hair growth on face, chest, underarms and groin
  • particularly in women
  • removed by removing class
36
Q

causes of hirsutism

A
  • stimulation of male androgens at puberty
  • medications
  • illness
    -stress
  • male androgens in blood
37
Q

hirsutism in women causes

A
  • hormonal imbalances
  • excessive androgen production secreted from ovaries/adrenal glands
  • menopause
  • may dissipate with time/treatment
38
Q

disease definition

A

pathological like conditions caused by viruses/bacteria with a series of signs and symptoms

39
Q

disorder

A

abnormally of function

40
Q

syndrome

A

group of symptoms that when combined characterize a disease or disorder

41
Q

disease affecting hair growth

A

acromegaly and Cushing syndrome - medical conditions related to excessive androgen production affecting hair growth

42
Q

disorders affecting hair growth

A

adrenogenital syndrome- malfunction of adrenal cortex causing over production of androgens

43
Q

syndromes affecting hair growth

A
  • polycystic ovarian syndrome (PCOS) - individual present with hirsutism, irregular menses, ovarian cysts, and obesity
  • Achard-Thiers Syndrome- combination of Cushing and adrenogenital syndrome
44
Q

types of soft wax

A
  • rosins
  • honey
45
Q

application to removal steps (8)

A
  1. pretreatment: cleanse and prep skin
  2. test: make sure wax is at safe temp and consistency
  3. apply: using spatula apply thin layer in direction of hair growth
  4. strip: quickly place strip over wax is temp and consistency
  5. rub: rub firmly over strip in direction of growth
  6. place: place on hand firmly over pulling end
  7. pull: swiftly pull against hair growth
  8. pressure: immediately apply pressure to waxed area
46
