Question

1. the ______ end of a surfactant molecule is water attracting.
2. the ______ end of a surfactant molecule is oil-attracting.
3. what needs to take place before the draping service?
4. the more alkaline the shampoo, the ______ it is.
5. list the 9 areas that need to be analyzed before providing a shampoo service?

Explanation:

1. Surfactant molecules have a dual structure; the hydrophilic (water-attracting) end is the polar head.
2. The non-polar tail of a surfactant is lipophilic (oil-attracting).
3. Before draping, a client consultation and hair/skin analysis must occur to ensure safety and suitability.
4. Alkaline shampoos have a higher pH, which opens the hair cuticle more, increasing cuticle swelling.
5. The 9 key areas are: hair texture, hair density, hair porosity, hair elasticity, scalp condition, hair moisture level, hair growth pattern, presence of chemical treatments, and client's hair care goals.

1. hydrophilic (polar head)
