Study Notes
Hair Growth Phases
- Anagen Phase: The initial stage where new hair is actively produced.
- Catagen Phase: The transitional stage where hair detaches from the bulb and becomes club hair due to loss of the inner root sheath.
- Telogen Phase: The resting stage where fully grown hair remains until shed.
Hair Growth Conditions
- Hypertrichosis: Abnormal hair growth in areas where hair typically does not grow, like the forehead or nose.
- Hirsutism: Excessive hair growth on women's face, arms, and legs, often linked to hormonal imbalances.
Hair Characteristics
- Gray Hair: Results from hormonal changes, characterized by coarseness and a deep root system.
- Red Hair: Tends to be coarse and more challenging to remove, often associated with sensitive, fair skin.
- Olive Skin Tones: Can experience significant pigmentation issues related to hair removal practices.
Hair Removal Techniques
- Permanent Hair Removal: Involves destroying the hair papilla, preventing regrowth.
- Galvanic Electrolysis: Uses direct current for chemical decomposition of the hair follicle.
- Thermolysis Electrolysis: High-frequency current generates heat to coagulate and destroy hair follicles.
- Photoepilation: Destroys hair bulb growth cells through intense light application.
Other Considerations
- Impact of Climate: Excessive cold can lead to dry hair and diminished luster.
- Hair Growth Cycle: Most effective hair removal occurs during the anagen phase due to active hair bulb activity.
- Hair Follicle Distribution: Approximately one-fifth of the body's hair follicles are located on the scalp.
