Study Notes
Nail Anatomy and Conditions
- Eponychium is a fold of skin that overlaps both sides of the nail, extending to the first knuckle.
- Nail plate or nail body refers to the area from the nail root to the free edge, containing no blood vessels or nerves.
- Onychophagy is the technical term for bitten nails.
- Improper trimming of toenails can lead to onychocryptosis, commonly known as ingrown toenails.
- Hyponychium is the tissue found between the free edge of the nail and the fingertip.
- Pterygium refers to the forward growth of the cuticle.
- If a fingernail is lost, it typically takes 3-6 months for regrowth.
- The root and matrix of the nail are located in the mantle; once the matrix is destroyed, it won't regrow.
Hair Cutting Techniques and Styles
- In the shears over comb method, holding the comb flat against the head results in longer hair.
- The most commonly used haircutting elevations are 45 degrees and 90 degrees.
- Angles below 90 degrees are typically used to build weight, while angles above 90 degrees are used to remove weight.
- A blunt cut, also known as zero elevation, solid form, or one length, is ideal for fine hair.
- Using double notched thinning shears removes less hair than single notched shears.
- A uniform layered cut is cut at a 90-degree angle, while a haircut using a 0-degree angle is referred to as a blunt cut or BOB.
- For longer layers in a graduated cut, a combination of 45 degrees and 90 degrees is recommended.
- The longest possible layers are achieved at 180 degrees, which also provides the most movement.
- Stationary guidelines are used in blunt cutting and to create gradual increases in length.
Hair Care and Treatment Recommendations
- It’s recommended to cut extremely curly hair when dry.
- Kinky curly hair should be cut dry before straightening.
- When cutting extreme curls, razors should be avoided to maintain control.
- When dealing with a cowlick, no tension should be applied during cutting.
Massage and Ergonomics
- Effleurage is a light, stroking movement applied with the hand or fingertip to relax the client during a session.
Regulatory Agencies
- The FDA mandates a patch test (P.D. Test) before the use of aniline hair tints and regulates cosmetics in the U.S.
- The EPA approves efficacy for products related to infection control, while OSHA enforces health and safety standards in the workplace.
Hair Structure and Composition
