Chemical compounds that absorb and promote the retention of moisture in the hair are called?
Emollients
Proteins
Humectants
Lipids
The correct answer is: Humectants
Chemical compounds that absorb moisture in the hair are called humectants. While emollients and lipids can also help moisturize hair, they do not specifically promote moisture retention. Proteins, on the other hand, have a strengthening effect on hair but do not absorb moisture. Therefore, the most accurate and specific answer is humectants.
