Study Notes

Skin and Hair Structure

  • Epidermis is the top layer of the skin, serving as a barrier.
  • Medulla of the hair strand has no known function.
  • Cortex holds the pigment and moisture of the hair.
  • Cuticle is the outermost layer of hair, made up of overlapping keratin "tiles" that protect the hair strand.

Hair and Scalp Care

  • Sebum produced by sebaceous glands moisturizes and waterproofs both hair and skin, preventing dryness and brittleness.
  • Normal scalp appears healthy, clear, and free from oil, flakes, irritations, or redness.
  • Signs of dry hair include lack of moisture, a weathered cuticle, and difficulty styling.

Shampoo Selection

  • Herbal shampoo is suitable for normal hair.
  • Coconut shampoo is recommended for dry hair.
  • Medicated shampoo is ideal for treating psoriasis and dandruff.
  • For oily hair, use lemon and lime shampoos or those containing citric acid.
  • Argan shampoo is best for color or chemically treated hair.

Hair Properties

  • Alfa keratin refers to hair in its natural state; beta keratin describes styled hair.
  • The cuticle's purpose is to protect the hair, while its condition can indicate overall health.
  • Signs of damaged hair include rough texture, dull appearance, and breakage.

Scalp Conditions

  • Dry scalp results from a lack of sebum, leading to tightness, irritation, and flakes.
  • Flaky/dandruff conditions are caused by a yeast on the skin that feeds on natural oils, causing itchiness and skin clumping.
  • Psoriasis on the scalp can range from mild scaling to severe crusting, potentially covering the entire scalp and causing discomfort.

Massage Techniques

  • Petrissage involves deep kneading movements to condition hair and promote relaxation.
  • Rotary technique consists of small circular movements stimulating the scalp during shampooing.
  • Friction technique incorporates fast rubbing motions combined with light, gentle plucking actions.

Hair Porosity

  • A porosity test determines which areas of hair are more porous; this is crucial for dyeing, as porous areas absorb color more quickly than less porous sections.
