Question

1. dry hair with average elasticity will stretch up to 50 percent of its length and return to its original length without breaking. wet hair stretches about 20 percent of its length. t f
2. the strength of the side bonds in the cortex is directly related to hairs elasticity. t f
3. hair with low elasticity may require a solution with a lower ph to minimize frizz; additionally, it might not maintain a strong curl pattern when chemical services are performed. t f
4. if hair feels brittle and breaks easily, you should take precautions to account for its low elasticity. t f

short answer
how should you analyze the elasticity of a clients hair? how will you determine if the hair has low, average, or high elasticity?
when hair grows at a perpendicular or 90 - degree angle to the head (straight out in direction from the head), what are three possible hair patterns that can occur?

Explanation:

Dry hair with average elasticity stretches up to 50 percent of its length without breaking and wet hair about 20 percent. The strength of side - bonds in the cortex is related to hair's elasticity. Low - elasticity hair may need a lower pH solution and may not hold curls well. Brittle, easily - breaking hair needs precautions for elasticity. To analyze hair elasticity, gently stretch a strand and observe how much it stretches and returns. Hair growing at a 90 - degree angle can have various patterns like straight, wavy, or curly depending on other factors.

Answer:

1. T
2. T
3. T
4. T

For the short - answer question: Gently stretch a strand of the client's hair. If it stretches a small amount and breaks easily, it has low elasticity. If it stretches up to 50 percent (dry) or about 20 percent (wet) and returns to its original length, it has average elasticity. If it stretches more and returns well, it has high elasticity.
For the other short - answer question: Three possible hair patterns when hair grows at a perpendicular angle to the head are straight, wavy, and curly.
