Final answer:
The scalp evaluation indicating brittle hair and red papules at the hair follicle openings suggests the condition could be folliculitis, which can be prevented by avoiding tight clothing and skin irritation and treated with topical antibiotics.
Step-by-step explanation:
During a scalp evaluation of a client who has brittle hair and red papules at the openings of the hair follicles, the condition that could be determined is likely folliculitis. Folliculitis generally presents as itchy, red bumps and pimples, which may be pus-filled, often resulting from the inflammation of hair follicles. Tight clothing, skin irritation, sweating, and injuries to the skin can contribute to this condition. To prevent folliculitis, avoiding tight clothing and skin irritation can be beneficial, while treatment for existing infections might include topical antibiotics. Unlike conditions such as psoriasis, dandruff, and alopecia, folliculitis is characterized by the red papules or spots specifically at the hair follicle openings.
