Which ingredients are included in scalp preparations for dry hair and scalp?

Cleansing agents
Moisturizing and emollient agents
Protein agents
Astringent agents

The correct answer is: Moisturizing and emollient agents

Scalp preparations for dry hair and scalp are formulated to add moisture to the scalp and help prevent flakiness, itchiness, and dryness. Moisturizing and emollient agents, such as oils, butters, and humectants, are included in these preparations to nourish and hydrate the scalp. Cleansing agents, such as shampoos, may be too harsh for dry scalps and can actually strip away natural oils, exacerbating the dryness. Protein agents, which are often found in hair products for damaged hair, are not typically included in scalp preparations for dry hair and scalp as they are not necessary for addressing dryness. Astringent agents, which are used to tighten and constrict the skin, are also not needed for dry scalps and may even cause further irritation. Thus, the best choice for ingredients in scalp preparations for dry hair and scalp is B Moisturizing and emollient agents.
